Do you have LTE menu option on your One? (not EE customers)

I am on Three UK, and although LTE is not rolled out yet, I was surprised that the LTE menu options do not appear at all. For example, why wouldn't I have this option in case I roamed to a foreign country that provides LTE to roamers.
In the network options I only have
WCDMA only
GSM/WCDMA auto
I know those on EE have another option for LTE.
Supposedly LTE and 3G SIMs are the same. In fact Three will provide free LTE access later this year automatically and without any administrative changes.
Could others confirm, if they are not on an LTE network, whether they see the LTE option on the phones network settings?

I think the phone only shows the option to turn LTE on or off if it detects LTE on your network so it should appear automatically once Three launch LTE

I agree! I decompiled Settings.apk of the HTC One and the network selection option uses RadioInfo class to determine what should be shown on the menu. In fact I can even see CDMA & EV-DO there.

Excellent. Perfect answers. Thank you. For some reason I had it stuck in my head that it was based on the SIM provisioning. I should have realised that it is based on the capabilities of the network you are currently connected to rather than a provisioning option.

I have LTE option on mine, got it on vodafone contract from p4u though the phone is sim free/unlocked.

Well done for finding that as it is buried in the P4U thread! Hopefully this thread will help others who wonder why they do, or do not, see LTE options in their menu!

Hi! Could you try remove the sim card and reboot your phone and see if the LTE option is still there?

Does this mean that it will work with AT&T LTE here in the US?

No. LTE bands in the US are way different compared to the LTE bands all around the world. I'm not sure about LTE Cat 3 though.

Can't select anything. Menu is gray...sounds logical to me without a SimCard

In reviews I keep seeing HSPA and LTE versions, which led me to believe there are models without the chip needed for 4G.
There is no answer on this though so I'm not going to rush to buy one until I know.

Do you have any other sim(Must not have LTE on it's network) you could try inserting?

GSM / WCDMA / LTE auto
SIM-free from p4u using Vodafone Italy SIM, in an area not LTE covered

Oh crap Now that looks like a sign that it should have LTE option nomatter what sim you insert.
By the way could you tell me what's your baseband version?

Baseband version:

I tested a T-Mobile Sim.

It´s not depend on the SIM/Provider i think

Custom ROIM's Texting broken

So how come no matter what Custom ROM I try I can't text or get LTE support what so ever? Maybe I'm spoiled but it seems pointless to me

Maybe.
Seems like you just wanted to vent. You didn't say what custom ROMs you have tried or any other useful details, which leaves me no choice but to assume that you either haven't tried many ROMs or are wildly exaggerating.
Most of the ROMs that I have used work fine for both SMS and LTE. If you post a better description of your situation, what ROMs you have tried, specific errors you had, etc, then we'd have a much better basis to help you.

On the 900P G5
phoenix ROM v2.0 & SpeedROM v4 DEODEXED. No error except APN settings are non existant, same with seeing the LTE feature on the network type at all, & when sending a text it times out and says try again with no error except did not send try again.

That implies that you have searched exhaustively without productive results. But you've only tried two ROMs. You are factually mistaken about the first ROM, and I'd wager about the second one too.
You said that there are no APN settings in Phoenix 2.0. I just reinstalled Phoenix and the APN settings are present in the expected place
Settings > Connections > More networks > Mobile networks > APN
SMS works fine as well.
For your LTE issues, you said that you are using a 900P model, but didn't say what carrier you use. You have a Sprint phone, so confirm that Sprint has LTE in your particular area and that your SIM /account is provisioned for LTE.
If you are using the handset on a different carrier then your LTE problems are due to using an incompatible phone, not ROM bugs. Sprint is a CDMA carrier, with limited LTE and even more limited compatibility with LTE on GSM carriers. This is not a ROM limitation, but caused because you have a CDMA version of the S5 that isn't configured for much more than the specific bands that Sprint uses.
Note that the specs for the 900P say that it can access LTE bands 25/26/41.
Now compare that to some GSM carriers
TMobile LTE bands 1/2/3/4/5/7/8/14/17
ATT LTE bands 1/2/3/4/5/7/17
Bell LTE bands 1/2/3/4/5/7/8/17
900F LTE bands 1/2/3/5/7/8/20
Or CDMA carriers
Verizon LTE bands 4/13
US Cellular LTE bands 2/4/5/12/17
You can see that most GSM carriers are largely compatible in the LTE bands that they use. The CDMA carriers in contrast have few bands in common with each other or GSM carriers.
In particular, your 900P doesn't appear to have any LTE bands in common with any of the other carriers. So the only way you will get LTE is if you are using Sprint in an area where Sprint has LTE service. Due to 900P restrictions, not the ROM.
.

Wrong LTE is available on sprint & in my area. And APN is non existent when using those ROMs. So its not my phone unless they don't support my phone

Good luck with your issues.

1. Did you used OLD SIM that you were using in your device before S5?
2. If yes than, Did that device had LTE?
3. If the the answer is Q 2 is NO, than simple solution, your SIM is not LTE activated. Just go to your service provider and tell them to change the SIM with LTE activated SIM... Hope it helps...

Unlock Verizon S7 edge

Hi Guys,
I have read lot of comments & QA's, still i have no clarity.Some one please clarify me.
If i buy S7edge Verizon (Sd820) can i use it in india.Verizon bands are 2'4&13. However i heard that verizon lte phomes are unlocked. Can i use in india lte network(Jio or Airtwl LTE network.
However locking is software thing(firmware), can i install international firmware (935U , not sure) to unlock all lte bands, to use any simin world....
Indian lte bands.
TD LTE 2300Mhz
FD LTE 1800Mhz
Please help

This appears to show that if you flash the U firmware, you should be fine (if the information from this website is correct).
https://www.frequencycheck.com/comp...5u-galaxy-s7-edge-td-lte-samsung-hero-2/india
It shows that the 935U is capable of Band 3 (FDD 1800) and Band 40 (TDD 2300) for LTE.

Sorry I am interested in this as well. May I know if you read somewhere that can confirm the unlock of bands by flashing U firmware? I am not sure if the U firmware contains the baseband that would unlock the LTE bands.

From what others say, the U firmware runs better since it doesn't have all of the Verizon bloatware. I guess it's up to you whether you want to or not, but I would recommend flashing the U firmware since you don't really lose anything except HD calling and visual voicemail. You'll be able to use your hotspot for free since it won't check to see if you're subscribed, and you will get updates from Samsung rather than from Verizon.

I have the S7 Edge Unlock on Verizon. I can confirm the hotspot works. However it sucks not having Wi-FI calling or Visual Voicemail. I wish there was a way to get both.

There is if you root your phone and flash on a different rom that's based on U's firmware but adds Verizon's extra tweaks and still no bloatware. But then you run into the problem of having horrible performance on your phone, some people don't mind, others flash back to stock. Pick your poison I guess.

I got a galaxy S7 edge SM-G935FD what do I need to do to make it work on verizon?

Verizon is a CDMA network and S7 Edge for Verizon was built only for CDMA networks (https://www.unlockunit.com/blog/cdma-networks/)
You can check your phone's frequencies, but I suggest that before placing any unlocking order, check with your local carriers if they support that phone.
Make sure you have all this info beforehand so you won't have to pay for a useless unlocking.

Verizon 3G on SM-G950U1

Just purchased the unlocked version of the S8. I'm able to get an LTE connection just fine, but I've yet to establish a 3G connection in places that I can on the Verizon version of the S8. Has anyone on Verizon, been able to get a 3G connection on the unlocked version? To be clear, SM-G950U1 is the unlocked Snapdragon US variant, that just started shipping on 5/27, not the unlocked international exynos variant.

Also, have you tried calling into Verizon to see if they can activate anything on their end? The phone should support their CDMA.

No, there is not. In fact, the locations of settings within the settings menus are laid out completely different. There is an advanced menu, and within that menu, the only thing phone related is an option to "identify spam," which is a replacement for Verizon's Caller ID service, only it's native to the S8 and doesn't cost anything. It appears that it's the "hiya" app, baked into the phone.
I have not had an opportunity to visit an LTE dead zone. However, in the past, when I have exited my parking garage or elevator (where I've dropped coverage) my phone's typically show a 3G connection first, and then moments later they will then show a 4G connection. With this phone, it takes longer to connect, and when it does, it connects to 4G, bypassing the 3G part of the process I described. That's what brought me here.
That said, I think I've answered my question:
According to Samsung's website the US variant of the unlocked S8 supports these bands/frequencies:
Network
Frequencies and Data Type
B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B12(700), B13(700), B17(700), B18(800), B19(800), B20(800), B25(1900), B26(800), B28(700), B29(700), B30(2300), B66(AWS-3)
According to Wikipedia, Verizon operates it's 2G/3G network over B0(850) and B1(1900). Of all the bands Samsung listed, I believe the Verizon ones are all LTE.
So, I guess the answer is that the unlocked S8 does not support Verizon's 2G/3G network, and I better hope that I don't end up in an area where Verizon only offers 3G. HTC's new U11 is the same way.

Direct from Samsung. I haven't, but my understanding is that you're on your own when it comes to unlocked devices. I don't think it does support CDMA, now that I've researched it more. See prior post explaining why.

I've seen your explanation, and it's very logical. The only problem is it directly contradicts what the back of a 955U1 box says - "Wireless voice, data, and messaging services compatible with most major U.S. GSM and CDMA networks." It also contradicts how Samsung did the S7/S7 Edge, being compatible with all four networks in the U.S.
Again, I'm not saying your wrong, but given that the G955U is the model used on all U.S. carriers and has full band compatibility, it just doesn't make sense that Samsung would do this. And yes, I know, Samsung doesn't have to make sense...

The band types you listed are only for LTE. Band numbers for GSM, And CDMA are different.
Try the dialer codes to see what RF bands are enabled. Dial *#2263# in the phone dialer to get the menu. Dialing *#0011# will give you current status of Cell radio.
I'm certain the phone has the required radios and antenna to support all Carrier network cell types but whether it's enabled is another story.

Do those dialer codes work for you? I can't get them to work on neither the Verizon SM-G950U nor the unlocked U1 that I have.
And yes, that's what my advanced calling menu on my Verizon S8 looks like as well. The unlocked version doesn't have that. Only an option to turn on VoLTE. No Video nor WiFi calling. Also, there's no visual voicemail, which sucks.

The codes do not work for me on my VZW phone., but works on my TMO phone.
I'm wondering if it's SIM dependent.

I was able to test another unlocked version today, and it had no problems connecting to Verizon 3G, so I guess I just have a bad device. If anyone else runs into this issue, exchange it.

Stumbled upon this thread while researching an unlocked S8 / SM-G950U1 for use on Verizon.
I found this web site, showing it is fully compatible with Big red.

Carrier compatibility.

Hello! My question I've nexus 6p 32gb Unlocked purchased from New Jersey.. But I'll be using it in India. So will it be compatible with all the carriers present here?
Thanks!

Okk..thanks...Got my Jio sim...Signal looks solid...for the first few minutes... but then it started fluctuating very much .. maybe changing bands every now and then coz jio operates on 3 bands 3,5and40. But as 40 is not present in American model, it switches between band 3(1800) and 5(850)very frequently...I got to know this from an app... So should I lock the band on 3/5 any of them(from network signal guru app) ? Will it stop fluctuating then?
