AT&T Tab with AT&T Data Connect plan with 3rd party ROM/modem?

Anyone out there using a 3rd party ROM/modem on an AT&T Galaxy Tab with an AT&T Data Connect plan (i.e. not one of the voice plans)?
I've been seeing an odd problem when on 3rd party ROMs where data would work at times, and then randomly stop working. Most of my experience came with various versions of Overcome (tried all sorts of modems) and JPE. I manually added the APN to be Broadband.
In order to get it working again, I'd have to do one of: (1) reselect the APN (2) toggle airplane mode or (3) reboot. It didn't always seem consistent which one of those was necessary.
I recently have tried returning to stock to see if that would solve the issue, and have managed to get it to mostly stock other than the bootscreens, and the issue seems to have disappeared. However, the problem was so random it's hard to know if it's gone for sure.
Can anyone who has an AT&T Tab and data-only plan talk about their experiences with it?

Wow, am I really the only one with an AT&T Tab and an AT&T data plan on this forum?
In that case, this thread should probably serve as a warning to anyone who ever gets an AT&T Tab and happens upon it, that:
1) AT&T Tabs must be running the AT&T stock ROM in order to reliably connect to AT&T data plans
2) If you flash any type of 3rd party ROM onto your AT&T Tab, you can never ever return 100% to stock. The AT&T Tab seems to have an incompatible bootloader with everything else, and even after restocking with my Roto Backup, I have permanently lost the boot animation and ability to boot recovery.

I am running Overcome, and the KM2 modem.
I get H,3G, Edge. super happy with it.

I recently upgraded to Overcome Jupiter (flashing a custom ROM for the first time), and bought another month of prepaid AT&T data to be sure everything still works okay. I've had no issues so far, no dropouts, errors, or anything. Can even stream Netflix over H/3G just fine! (only to test, it eats the data up quick!)

Hmm that's pretty interesting. You're both on AT&T Tabs right? With the AT&T Data Connect plan (I'm on the 14.99/month for 250MB variant)?
Did your Data Connect plan come pre-activated on your Tabs? If not, did you have any trouble when you first signed up?
I picked up my Data Connect plan (with a new sim) after using my Tab with no plan for a while, and when I went to activate the plan in Overcome, it was extremely fritzy. Even after setting the right APN info, it took a bunch of reboots and changing settings back and forth before it mysteriously started working after a reboot with settings I had already used. And my data has been fussy ever since, with multiple modems tried, and also trying the JPE ROM.
After reflashing to AT&T (minus all the messed up parts I noted) things seem to be well-behaved on the data front now.

Yep AT&T Tab with AT&T plan. I didn't have the data plan pre activated, did it myself on the internet a few months ago with the SIM that was in the Tab when I bought it slightly used on EBay. Bought the 2GB plan for a month on the stock ROM, then this month, got the 25MB plan on Overcome Jupiter to test it out after the upgrade. No issues signing up, or getting data after the upgrade.
BTW, forgot to mention, when I flashed Overcome, I went with the modem recommended in the Guide (JK3). No issues with that at all.

any of you guys have this all work with VOICE? ie, Overcome on AT&T tab, with 3G and modem that supports voice?

I don't and don't think I can test either. If I remember my research right, you need a different SIM for that that supports data and voice, the SIM that comes with the tab is a data only SIM.

Complete false statement.
I tested many EU/Asia tab modem worked well with at&t 2G/3G.
you always can 100% return to at&t stock firmware (if you get right one, or well backup one)

Regarding the first statement, that the connection to the AT&T Broadband APN requires stock, I now believe that I was wrong, and I may just have a hardware problem based on feedback from others.
However, there really is no way to go back to AT&T stock firmware, because the "right one" was never released. The other Galaxy Tabs can go back to stock, because their stock firmwares could be just pulled from Kies, but the AT&T Tab's firmware was never on Kies.
Like I said, I have a Roto Backup of my stock AT&T Tab. It still displays corrupted boot animations/recovery after restoring. If you search through the forums, there are other people that have run into this issue, and no one has ever reported being able to solve it.

Get one from Samfirmware.com, check P1000 section to look in at&t one (under provider), it pretty much compete restock to att stock firmware with original boot-loader.

I'm not seeing anything labeled AT&T in the provider section, are you saying one of those is the AT&T stock firmware?

I have a stock galaxy to the that I ordered with a data plan, and the connection disappears all the way if I open the android market. Once I kill the market the modem pops back up. This is very annoying to say the least. I wonder if you are opening the market when this connection issue occurs?

Mine did exactly the same thing when I opened the Market. I took it to an ATT store and they switched out the SIM card and it still did it. I flashed Overcome and have not had a drop out since and my speeds are great.

Nope, my problem seems quite random, isn't correlated to opening the market.

I've got exactly the same problem with my Samsung Galaxy Tab SGH-i987 with stock firmware, and this only happens on 3G, not Wi-Fi. Also, sometimes the Market works for a while if I reset the APN to the default (ATT Broadband).
I've gone through the whole SIM Card swap out process, and was about to start a warranty exchange. Seeing that others have been having the same problem and that there is a possible solution gives me hope.

Possible phone use on Verizon 7.7

Let me note: I am not a dev nor programmer.
With the similiarities of the P6800 and the Verizon 7.7, I threw together a rom w/ stock SCH-I815 samsung/verizon kernel using the P6800 frameworks and apps into the Verizon 7.7 and removed most bloat. The LTE/Verizon antennas aren't recognized by the device at all but everything else was working.
Now, you can't swap the phone.apk's around without the framework's else you'll experience FCs. So obviously I'll need to use the base stock apps and frameworks and go through the 2 framework files hunting about.
Has anyone else with the Verizon 7.7 taken a look into this?

I'm curious if you've made any progress on this?

Not yet, probably be a week before I even look through the files again. But I believe it's fully possible to get phone use

i think you will need to find samsung modem for verzon networks, does verizon have a galaxy note or sgs2?
although your modem firmware probably has voice disabled, may have to find modem manufacturer and try to flash custom firmware.
good luck, wish you the best.

I'm happy enough using GrooveIP for google voice calling. What I'd really like is if we could activate the phone profile in bluetooth (or will that just come with enabling the proper phone part in the 7.7?).
As of now i can use GrooveIP and bluetooth to listen and speak, but it won't let the bluetooth device answer/hang up/transfer address book/show caller ID (on the Verizon LTE 7.7)

Doesn't verizon require some sort of signed telephony to work properly on their network

I got no idea but with the other packs it didn't detect the radio at all. This is keeping the vzw radio partition stock. I like the ideas and really wish the note was verizon as that'd help figure things out.

It does for LTE but cdma service doesn't use sim
Sent from my GT-N7000 using XDA

Seeing as your data account won't have any provisioning for voice usage, even if you DID get a working modem and a modified framework to allow for phone functionality on the device, I doubt that you'd actually be able to made or receive a phone call due to Verizon's limitations at the account and provisioning level anyway.
Point is, it's a CDMA device, and thus your service is attached to the device itself, not the SIM card (except for LTE data). Basically, you can't just provision service to the SIM card alone, and then simply swap it into a different device. So if you got the modem and the framework working, and you called in to Verizon customer service and asked to provision your line for voice, they'll just be like "Umm, no... We never INTENDED for you to use that device as a phone, so no... You want a phone? Buy a phone. You want a tablet? Buy a tablet. You want to do both in one device? We won't allow that because that loses us money that we would be getting by having you either subscribe to two lines, or charge you extra to tether..."
There is a much simpler solution however.
Ditch ANY CDMA carrier in favour of a GSM carrier instead, preferably one that uses the same compatible frequencies adopted by the rest of the world, like AT&T (and MVNO's based off of AT&T's network), and buy the P6800.
The moral of this story is this: if you want the latest devices, with the best features, you're NOT going to find them in the north American market, EVER, at all, period; you're just going to find watered-down, gimped, bloated, and locked-down versions of the international models. You HAVE to import. If you're going to import, you HAVE to use a GSM service provider... That's just the way it is. It sucks, I know, but it is what it is.

I would have to agree, the GSM version would be best. It would be near impossible to make this happen. Of course if I was stick with one, I would try everything I could as well. I'd probably fail miserably and go for something like GrooveIP.

I move my SIM between devices all the time and have never needed to call VZ to provision the new device. Voice and data just work.

I can CONFIRM the following:
I have a VZ tab 7.7 with 5GB data plan and I have a VZ Razr with voice/unlimited data plan.
Both are LTE devices and hence use (micro) SIM cards. In "My Verizon" even the tab has a phone number assigned to it's "line". A call to that number just rings but obviously nothing on the tab.
BUT...
Put the tab sim in the phone and YES it will ring if you call that number! Even TXT in/out works! I assume they will just charge me per txt and per min phone use BUT IT WORKS in a PHONE.
And the kicker is, the unlimited PHONE SIM also works in the TAB! I immediately get LTE data and can surf with the tab. Of course at that point calls and texts to that phone number are "ignored" by the tab's neutered modem.
Lesson learned:
IF there was a way to flash a modem, say for example from the Samsung Galaxy Nexus to the VZ 7.7 TAB, we would have a full supersized phone in our hand. Only downside, no earpiece. So only speakerphone or BT calls I guess.
Anyway, after a little more research I also found this very interesting article:
http://www.phonenews.com/verizon-affirms-unlimited-smartphone-sim-card-usage-in-hotspots-tablets-lte-ipad-20053/
Hope this helps bring a little light into the messy CDMA/LTE darkness

I have swapped my Galaxy Nexus SIM in my VZW LTE 7.7 numerous times. It works. I'd love to have voice on the VZW LTE 7.7, then I could possibly do it all on my tab. I'm no developer tho ;p

The Ntelos S5

I have an ntelos S5 (G900R7). There is no development for this phone anywhere on the internet. Perhaps I can find support here?
---------
So far (you may skip this part):
I have managed to successfully install Spirit Rom with full functionality, by copying my old build.prop into the system directory, and restoring my previous apn settings using the apnsbu. I forget why I left this rom, but I did. Everything I try has some problem! I then proceeded to try just CM11, by itself, and had 3g difficulties. Then, using Kushman's sprint MIUI, (Ntelos shares sprint towers) things seemed to work right, but it remapped my recent app key to menu... (perhaps I can map it back?) and the volume was not controlled by my physical volume buttons.
-----------
Now my favorite rom so far: Mokee Rom It's fast and visually pleasing, but I have wi-fi and phone difficulties.
After imposing my APN settings, I can reproduce these effects:
(1) Before replacing build.prop, the wi-fi works and can be enabled or disabled as I need. Also, 3g works very well at nice speeds, but it says "Verizon Wireless" underneath the 3g indicator bars. However, I cannot make calls. If I attempt to do so, the 3g data stops working, turns orange, and no longer says "3g". If I do this, then no data can be transmitted or received.
(2) After Replacing build.prop with the "good original" copy (which sometimes fixes similar problems in other custom roms) the wi-fi becomes stuck in a constant state of "turning wi-fi on..." but never turns on. 3g still works, but, as in part (1), it will break if I try to make a call.'' Also, in this case it says "Sprint" instead of "Verizon Wireless"
Does any one have advice, or perhaps some build.prop settings to modify? Or maybe there's a different file that would help. Again, my phone is the SM G900R7. Has someone else with this phone had luck customizing it?
Thank you

nTelos S5
Likewise have a nTelos S5, have not found any custom roms that can successfully be installed without data or phone issues.
Also trying to install any ASOP roms resulted with all phone efs data getting cleared.
Upon searched relentlessly the only rom I found that functions is located at
http://teamcspire.com/index.php?/topic/112-gs5-g900r7-r2-teamcspire-nd8stock-deodexed-101814/
its very stock but functions flawlessly for me.
Advise if you have any luck, I will reciprocate.

My advice is to you, is that if you install Mokee rom, do not update it with OTA update. This is what I think broke the network for me. Even after restoring my phone to factory conditions and using Kies, I still had no network. I ended up going to the nTelos store, where they had to reset the network service for my phone on their end... strange.
Anyway, I have made a few roms work, and I suspect I could make more. If you maintain your apn settings, and build.prop, you should be able to make Spirit rom work. The same thing is true for Miui. However, if I remember from my experience correctly, if you do install Miui, then I THINK you should not restore your original build.prop; it may work without it... just restore the apn settings. When you do this, you may have to change the preferred network mode... I am a little freaked out, after my previous experience with Mokee rom, to mess with this any longer, though. I do have a problem with Spirit rom: if I use the Timely alarm clock, the time panel is miscolored, but I believe that could possibly? be fixed by flashing a different kernel. I plan on flashing Spirit tonight.... stock uses up my battery too fast, and Spirit just feels more responsive.
EDIT: I just re-flashed Spirit Rom, and they fixed the discoloration in the most recent version! Also, as before, my 3g and WiFi work fine.

Took me days...
The CSpire shares the model number and ROM. The US Cellular CM11 is the closest. Somewhere in that I lost my ability to send texts (not sure if it's the SMSC or...) and didn't get it back when I ODIN'd to stock. I would LOVE to have CM support for this model.

I also am in the same boat as you guys. I would love to get another reliable ROM on this phone. I just have bad memories of purchasing my last one (Sprint GS3) from ebay, and having one hell of a time making the MMS work after flashing it for nTelos. However, I never did have to mess with any of the APNs or build.prop settings on that one. I would think the Sprint ROMs should be the closest compatible ROM, being that nTelos and Sprint do share towers in WVa and Va (Sprint actually has zero towers in these states, and leases nTelos towers instead).
Is using EFS Backup by Wanam a good method to insure the EFS does not get screwed up?

You might try saving out your wpa_supplicant file from the stock ROM and replacing it on the flashed ROM. This has worked for me before on my GS3. That might take care of the wifi anyway.

I'm also on ntelos with the s5 now. But it is a us cellular unlocked by them phone. Stuck in a ntelos sim card that I bought from store and everything works. Except 4g. I can live w/o it but it's kinda like a puzzle now. How could I enable this to work on ntelos?

Depending on where you are, ntelos does not have 4G in many places yet. It's still very spotty in West Virginia.

Has anyone taken the OTA Lollipop update? If so, how is it working and does it lock or put in a new bootloader?

I have. It's a little laggy at times, gets really hot when using it while charging and battery drains a little faster. Not sure about the bootloader

I think I will hold off for a while. My stock NK1 is laggy enough as is. Damn, I wish there was a compatible ASOP ROM available for this phone.
Honestly, this Samsung G5 is the absolute worst phone I have ever owned! I would like to get a S6, but my experience has been so bad with this S5, I am almost afraid to stick with Samsung. However, my S3 was awesome!

Just found out that the heart rate sensor is active when the phone is on no matter if S Health is open or not.

I am in the Richmond area on Ntelos. They have stated they have sold their bandwidth to T-Mobile and we are to find another carrier. My phone is not even a year old and no other carrier will activate it. Being I own mine outright and paid close to $600, I am about to lose my mind knowing that I will have a shiny expensive very small tablet in a few months. Has anyone a clue how to change this phone over to GSM or something useful. Verizon refused to even try, though I know when I tried Straight Talk's Verizon Sim it did dial to Verizon's customer service. But Straight Talk nor Verizon would activate it.
Ideas and suggestions welcome.

page plus,i am an ntelos dealer and pageplus dealer i flash phones to and from both companies everyday i am in ruckersville va 12 mile north of charlottesville lemme know if you need help you right its the enitre eastern side of the companyh is gone now to tmobile but you can still activate on frawg..ive done many for customers

Thanks for the info. I am on the frawg side of things now. Their plans were too much when mine ended and I didn't need a phone at the time. Then a few years later, yeah I made my S1 last almost 4 years, I bought the S5 late last year outright. Loved the S1. Made that do everything it just did everything slow at the end.
Anyway, am glad there are options of some sort. Have been reading the reviews of pageplus. What kind of speeds are you getting on it with 4G? Their map shows coverage everywhere which makes me a bit uneasy, as in too good to be true. Is it a simple flash or require editing?
If I can't do something else with the phone, I may try the band opening options. According to the phone specs, it should already have all the Verizon bands but they refuse to activate it due to the meid it seems. I have a feeling this topic may get more viewers as the Ntelos off switch day comes closer.

Google Fit was the culprit for the heart rate sensor staying on. Un-installed it and fixed it

After all this time, has anybody found a ROM that works well on this phone?

AT&T WiFi Calling on SM-G935F

I have been trying to get wifi calling with AT&T is working on my International S7 edge. I have made headway.
1. First of all I told AT&T I had their branded S7 edge and gave them an IMEI that will show up that phone. So I can activate my phone.
2. I have narrowed down the required apks to the following, but some are obviously for the Wifi Calling, and other's I am not sure. If people know what some of these apks do, please let me know.
3. I have used the Note 7 Port and flashed TTKG CSC selection and chosen the ATT CSC, we are still working on getting it working in the S7 and Edge CSC.
4. The following APK's I feel are related to Wifi Calling are.... If you can help me eliminate some that aren't. They are deodexed, and I have uploaded them, you will need to change the permissions to match the ones in the system folder.
atfwd
ATTVoWifiSPG
com.quicinc.wbcserviceapp
NSDSWebApp
VolteSettings
vsimservice
WAPPushManager
Wispr_ATT
AppSelect_ATT
5. I am unsure if I need to make Buildprop changes or I am missing other system files. I was able to activate wifi calling and turn it on, but it doesn't work.

1. First of all I told AT&T I had their branded S7 edge and gave them an IMEI that will show up that phone. So I can activate my phone.
2. I have narrowed down the required apks to the following, but some are obviously for the Wifi Calling, and other's I am not sure. If people know what some of these apks do, please let me know.
3. I have used the Note 7 Port and flashed TTKG CSC selection and chosen the ATT CSC, we are still working on getting it working in the S7 and Edge CSC.
4. The following APK's I feel are related to Wifi Calling are.... If you can help me eliminate some that aren't. They are deodexed, and I have uploaded them, you will need to change the permissions to match the ones in the system folder.
atfwd
ATTVoWifiSPG
com.quicinc.wbcserviceapp
NSDSWebApp
VolteSettings
vsimservice
WAPPushManager
Wispr_ATT
AppSelect_ATT
5. I am unsure if I need to make Buildprop changes or I am missing other system files. I was able to activate wifi calling and turn it on, but it doesn't work.

Did you ever get this resolved? So far I can not for the life of me, get WiFi Calling working on my S7 Edge exynos. Basically throws an error stating the activation failed, and never brings up the screen to enter in my emergency contact address like AT&T is supossed to re-direct you to.

The activation fails because AT&T doesn't have an AT&T wifi capable phone on your account which then allows you to activate the wifi. I have two imei's that are linked to AT&T s6 and s7. I can give you the imei. Go to att tech support give them the imei and tell them to update your account to be able to get visual voice mail and wifi calling. After you do this, they will alow you to activate it. However I gave up after a while. If you flash the custom csc, you must do it before your phone boots up after a factory reset and flash a custom rom. I am waiting as I am on Nougat now, so until ATT updates it's apps again.

Thanks, although I'm a bit confused on the steps your outlining here. I assume you're stating that I'll need to somehow modify a ROM (in this case SAC's N7 ROM for S7 Edge Exynos), and inject an IMEI? I'm not entirely sure how to do that to change the IMEI (this would be my first time attempting to do that). Then I would reflash that image, and then re flash the CSC update to AT&T? Maybe I'm not understanding, but my iPhone 6 is on my account and fully capable of wifi calling. In fact we have 2 iPhone 6s on the account. What exactly did you give up on?
Hate to sound like a newb here (although in a way... I am), but can you step me through the process so I can follow your line of thought? Appreciate the help!

So first of all an Android WiFi Calling and IPhone Android WiFi calling are different you will need to tell at&t you have an AT&T branded Android phone that has WiFi calling. This will lead at&t to add the ability to add wifi calling on your account.
Have you rooted your phone and installed a custom rom? If so then you would flash ttkg84's csc package and choose att. Which will flash most if not all the files. I got all the way to confirm my address and enable wifi calling, but it never worked.
Do not insert another phones imei into your phone, you will brick it and will have a expensive paper weight.
I have given up for now and am waiting for a full release of Nougat.
PM my I can give you am imei to give AT&T to enable video calling, visual voice mail and give the ability to activate WiFi Calling, but it's not likely to work. Some things are still missing.

You may never get wifi calling working because at&t uses a slightly different method then everyone else. I think they will standardize with Nougat.

That's what I thought.... So what about the King of Nougat ROM that's lingering out there currently? I realize Nougat is still beta, but have you tried the beta?

I haven't tried King of Nougat. I am currently using Nougat? Are you on telegram?

So... Interestingly enough. I just got WiFi Calling to work this morning...
Basically, I did the following steps:
1. No SIM Inserted into Galaxy S7 Exynos - SD Card only
2. Reboot to Recovery
3. Wipe
4. Download and Install SAC23's Full n7 ROM located here: http://forum.xda-developers.com/s7-edge/development/rom-n7-rom-port-romcontrol-t3430358 - I did the V8 Debloated version
5. When prompted - Wipe Dalik
6. Insert SIM Card from AT&T iPhone (ensured WiFi Calling was turned OFF on the iPhone prior to removing from iPhone)
7. Reboot first time into N7 ROM
8. Go through the setup and connect to a WiFi location that you know WiFi calling works at.
9. Download a browser (Chrome or whatever) at a minimum
10. Eat a Bacon, Lettuce, and Tomato Sandwich :good:
11. Reboot to Recovery
12. Flash CSC for the N7 located here --> http://forum.xda-developers.com/note-7/development/utility-flashable-csc-selection-v1-0-t3450911 - Grab the CSC snapdragon the Exynos zip
13. Reboot
14. Status bar will indicate VoLTE enabled up at top eventually.
15. Try going to the pull down from the top, and clicking WiFi Calling option a couple times.... no dice.
16. Try going to the phone app --> Click Settings --> Note WiFi Calling is off --> Try clicking it on a few times.... you'll get an adroid app stopped working.
17. After sitting on this sceen for a few minutes, note the VoLTE dissapears, and the icons on the phone app screen (The Call Start Button and the Call End button) switch to WiFi magically.... Try making a call with 0 zero cell reception, and indeed, the call is being made through WiFI on AT&T's network.
Now.... I have absolutely zero idea what's going on with the VoLTE icon disappearing.... and the WiFI calling suddenly working. If you reboot the phone, the same thing occurs. It starts in VoLTE.... and then eventually disappears, and eventually after a couple of minutes being connected to a WIFI connection, switches auto-magically to WifFi calling.
I'll take some screenshots.

Followed the method above using Superman 1.16 and CSC selector 1.86.
Haven't been able to test wifi calling since I haven't found an area with wifi and no cell reception, but so far everything looks like it's working.
Important to note that the AT&T account probably does need to be provisioned for a G935A rather than G935F, which is done by reporting a G935A IMEI to AT&T (and not changing it on the device itself) as mentioned previously.

Hmmm, gotcha.... but if you report a G935A they typically want you to power off and power on the phone to check the provisioning while on the phone with them. And what happens if someone calls in and then tries to re-provision the same IMEI on another account? What happens to my SIM in my G935FD? Thanks!

Far as I can tell they don't check IMEIs against different accounts.
I can't say for sure, but I haven't had an issue as my phone has a different IMEI (or IMEIs--G935FD) than the one listed on my account (which reads as a G935A).
In short, asking AT&T to change the IMEI on the account hasn't affected or changed the IMEIs on my phone, or caused any problems.
As far as provisioning, I told them I was on the phone, so they called me back a few minutes later and didn't report any issues or discrepancies to me.
It'd be just as easy to tell the rep the phone isn't available though, so just ask them to change the IMEI and you can call them back later if there are issues if that's a concern.

Looks like great news. I was happy I was able to activate my 935F via AT&T (I gave them the actual IMEI and they activated it). I'm on Superman ROM and flashed ATT CSC. I get visual voicemail and the WiFi calling button, but it doesn't actually work. I'll see if I can get a valid 935A IMEI and ask them to activate again. Hopefully that will do the trick. I get a horrible signal at home, and the 4G/LTE icon is constantly flickering on and off... AT&T Video call option shows up in settings, but won't turn on... no wifi calling setting in the settings menu, just the quick settings button.
Any guidance appreciated!

Note 8 hotspot hack - grandfathered unlimited Verizon

I found a trick that works to enable the hotspot if you have an unlimited plan with no hotspot included. It works on my Verizon Note 8.
You follow everything in the video, except you only disable the red "mobile hotspot and tethering " app. Not the others.
It helps if you have Wi-Fi and mobile hotspot in the quick swipe down menu of your phone. Once you set up the wrong passworded Wi-Fi all you have to do is toggle them in the drop down. It's easy and fast.
Let me know if the link doesn't work.
https://www.google.com/url?sa=t&sou...CC4wAw&usg=AFQjCNGLD66UrxdFo9tyLyXax3CAc0inCg

No go. I just get this error message no matter what when the hotspot is disabled - "All apps associated with this action have been turned off, blocked, or are not installed."

On mine I have Wi-Fi sharing enabled in the hotspot settings and also make sure you only disable the one app, not all 3 like the video. Hope that helps. Not sure if it'll make a difference.

Attached a picture of the package disabler.

I thought I had wifi sharing on already, but I guess not. That did it, thank you!!

not sure if this will work for Verizon but I found this method on galaxy s8+ and works on sprint note 8.
Hotspot hack works here as well. Seems easier than the other method.
1. Download Shortcut Master Lite
2. Search for LTEfunctionality
3. Click on com.test.LTEfunctionality
4. Launch
5. Scroll down to LTE APN Setting
6. Add " ,dun " to APN2 LTE and EHRPD internet under APN type. That line should read default, mms, dun when you finish.
7. Native Hotspot should work. You may have to do this hack again if you update Profile.

I have a VZW N8 and nothing happens when I try to launch com.test.LTEfunctionality. I tried to modify the APN settings through ADB already, and that didn't seem to take either, so I think Verizon just has the APN settings locked up pretty tight.

Do you guys have carrier locked or unlock? I still have unlimited from 2009 and the hot spot works just fine without any of this on an unlocked version....

I'm on the locked VZW, but also still have the grandfathered unlimited.
If I knew that workarounds would be available for all the network specific features, I would have definitely preferred unlocked.
Though I would not have gotten anywhere near the deal I got for the locked VZW...
So in an effort to make this as convenient as possible, I made a Bixby quick command to perform the necessary actions.
First off, I had to install the app WIFI Prioritizer and set the wrong-passworded network as #1 priority, with auto switch on. My other wifi networks all have auto switch off.
Quick command as follows:
1- Turn off wifi
2- Turn on wifi
3- Turn on hotspot
4- Turn off wifi
The timing of Bixby's execution seems perfect, however, there's a big caveat...
It seems wifi-sharing is turned off every time after disconnecting from a wifi network (including just turning wifi off when connected to a network).
I have not figured out any way to have Bixby turn wifi sharing back on.
So basically, unless you never connect to wifi, the quick command won't work without also manually turning on wifi sharing.
If anybody has any suggestions to deal with the wifi sharing issue, please let me know!

I have the Verizon version of the phone. Which is technically unlocked but with the Verizon firmware. If it's like the vzw s8 then we should be able to flash the unlocked firmware to it and the hotspot will just work. But the Verizon firmware locks down the hotspot unless you pay, or find a hack around it.

Dr, so just to confirm you have the carrier specific locked version. That would explain why you need to do this work around.
I have a non carrier specific unlocked phone on VZW network which activates the hot spot just fine without any of this.
Only reason I'm posting is to help pin down who needs this mod.
Im also used to flashing the hotspot apps when I root a new phone, which is over of the main reasons I root however I don't need it with note 8.

Does an unlocked phone on Verizon still get throttled after 15GB of Hotspot Data? I had been using an S3 with Foxfi and never got a message about using Hotspot Data till yesterday. Was looking at possibly getting another unlocked Note8 to serve as a Hotspot if I wouldn't get hit after 15GB on Verizon's new unlimited plan.

Once I dl'd PDP from their page I could disable, but then I cannot select Mobile hotspot.

The best solution for Verizon phones is to flash the unlocked firmware onto your phone. Super easy and problem solved. The one downside is you will lose vvm and wifi calling, but I don't use those anyway. And you get rid of the Verizon bloat.

It is quite simple. Flash the Unlocked firmware on the phone using Odin/Prince Comsy's Odin, check the link below:
https://forum.xda-developers.com/ga...m-n950u-u1-t3685884/post74087340#post74087340
Optional: Set up the Video Calling (VoLTE) by following the steps from that Youtube video:

@Proweedsmoker: thanks for your post. i relied on it when i ordered my unlocked note 8. i have an unlimited data plan from 2004. the phone arrived yesterday; it "only" took 2 weeks to arrive. i went to verizon to get a micro sim card (since the sim in my note 3 is the larger version). they activated it and first thing i did was turn on the hotspot to see if i could get wifi on my note 3. it worked perfectly. huge relief; no rooting, flashing or potential brick-making procedures. i'm loving this note 8 so far.

It's a great phone but I keep going back to the V20 because of my 3 main reasons: Hi-Fi sound, Interactive 2nd Screen and the ability of picking up a call by bringing the phone to your hear.
