Hey Guys,
So, I bought a AT&T LG G2 phone (I had a gift card at Best Buy- they don't carry T-Mobile). I heard that AT&T had the same towers so it's easier to work with an unlocked phone through them, so I bought it there instead from T-Mobile itself.
However, now I realized I don't have some of the features I would have on a T-mobile LG G2, such as my wifi calling, etc. Now, since the phone is unlocked (and I just got it rooted), would installing a T-Mobile rom affect my phone in any way, good or bad? Should I only use AT&T roms? How would I use T-mobile app services?
I searched google for 2 days and couldn't find anything relevant to my question. I've used this site a lot in the past year-two for rooting and such. Thank you guys in advance for continuing to support open development for android.
Wondering the same, about to switch to tmobile.

Well, seems like no one has an answer to it...
Anyway, I went ahead and bought the phone. Since I do a lot of testing and rooting myself, this was the first time working on this type. I'm glad you posted, because I would have just forgotten about it now that I've solved the question I had... However, I figure it'd help in the future in case someone is also wondering the same.
Now, with that all stated... down to the answer.
If you bought an AT&T phone, and do an unlock code to use it on another carrier (such as T-mobile since they use the same towers), the rom you MUST use are the AT&T roms... NOT the T-mobile roms. The problem is, when you buy a AT&T phone, unlock it, and root your device to use another rom, it will not be compatible with T-Mobile roms because of the image files, etc. So yes- you will be losing all the features a T-Mobile rom would have such as wi-fi calling, etc...
However, a way to go about this (and it won't work with ALL the features that comes in a T-Mobile phone/rom), is to install a AT&T rom of your choice without all the crappy AT&T bloatware that you can't even use, and go to the T-Mobile section to look for an APK version of the files. Most of the time, T-Mobile roms will also remove the bloatware, however, some developers are kind enough to provide the bloatware APK files in case users would like to have certain one of them features, such as WiFi Calling.
So, that's how I did it, and it's working good.
PS- One last thing, you may have trouble going on the internet or playstore when you're unlocked to a different carrier. All you need to do is find the APN settings for your carrier. So in this case, I bought an AT&T phone, bought unlock code to use on my carrier T-Mobile, and got the T-Mobile APN settings set up, reboot, and I get all my 4G data, etc. You can get this by calling T-Mobile. Just say, you bought an unlocked phone and can't access data, internet, etc, and was told to set up a APN. Or, you can use google. :good:

So, would I be correct in stating that you will only get 4G in areas where it is offered @ 1900 MHz? What about 2100 MHz? Otherwise you will only get 3G HSPA+? As you can tell I'm a bit confused about compatibility between networks. According to wikipedia they will be doing away with 1900 MHz 4G by 2015. I'm trying to decide if it's worth buying an AT&T or Verizon phone to use on the T-Mobile pre-paid network because it seems the T-Mobile phones are not getting very much development.

Bought phone from ebay, it is an AT&T phone unlocked and want to use for T-mobile./ With T-mobile network I have to use wifi calling features in order to use in the house.
Could you please explain me how and how much it cost to get wifi calling feature in LG G2 ?

Hello,
I'm in the process of deciding between the HTC Arrive on Sprint, and this phone, purchased unlocked and running on at&t. I plan on using it as my main phone, and for development.
I have been looking around for people's experiences with the Optimus 7 on at&t but haven't found much. I have never used an unlocked phone before, so I am not sure how easy the setup will be. Does 3G and MMS work for you? How will updates get installed?
I have been reading the posts on this forum, but I haven't read much about at&t yet.... I have no idea what I'm doing, haha.
Thank you very much for your help!
It works pretty well for me. The signal is a bit worse than with "native" AT&T devices because the radio ROM isn't customized for AT&T's network, but overall 3G/HSPA works well. I've never actually tried MMS, but I'm assuming if it doesn't work, you can use the MFG app to fix up your settings.
If you have an unlocked device, updates will come from Microsoft without having to be approved by AT&T, but you'll still get the AT&T exclusive apps in Marketplace because that functionality relies on your SIM card.
I still don't have NoDo, but apparently a lot of other people with this unlocked phone don't either, so that would probably be the main reason to go with the Arrive, as it comes with NoDo preinstalled.
Thank you Arktronic! Man, this makes my decision even harder now, I was just about to walk out the door and go to sprint. I really like having a physical keyboard and getting the phone *now* rather than having to wait a week for it to ship in. Haha, I have no patience...
Ahh man...
I'm still a bit worried about those updates....but I do plan on doing a ton of globe-trotting this year and next, and I don't want to pay for another phone to work overseas. Decisions!
Thanks again!
Keep in mind, only the LG E900H is optimized for North American networks. If you have an LG E900H (different from the more widely available E900), then you can simply go to the MFG app on the device, and set the network profile to AT&T, (with a couple of other changes, such as automatic WCDMA and ADC Enable, all of which can be done without any modifications, and very simple to do), and suddenly your device works like a native AT&T device. I have tried this on my LG E900H Telus branded Sim unlocked phone, and I tend to travel across the border a lot. If you have an AT&T sim in the phone, and you do all the above, you even get the AT&T splash screen...so completely AT&T-fied.
Man, I'm having a really hard time finding the E900h (what I can find costs >500 USD). Is that the phone that was given away to devs?
When you say 'optimized' you just mean that the setup is a bit easier? From what I understand, it seems like I should just be able to throw in an at&t sim and I should be good to go. Am I missing something?
I just want to make sure I can get 3G/MMS! (and not EDGE haha)
Thank you for your help!
I have a non-H and 3G works just fine.
E900H is available through Telus in Canada and I think some other carrier that starts with T in Mexico. And both versions will have the AT&T profile, and will work fine on AT&T.
Thanks a lot guys! I bit the bullet and just put in an order for it.... at 3am, haha. As much as I like the Arrive (and my Sprint service), I really fell in love with the Optimus 7 when I held a demo unit (that wasn't even working) when I was in Hong Kong. I hope this process goes smoothly... (and that we can get NoDo soon! Oh and I hope at&t service/reception doesn't suck as much as I'm afraid it will.
I've already written a crappy app, I can't wait to see how it works in the real world!
Cool, good luck!
Yeah I got it!!! Reception seems about on par with other at&t phones, perhaps a bit worse. Just installed the MFG app, set it up with the at&t_410_310 setting like it was mentioned elsewhere in this form, and bam it worked! I usually get decent reception on the HSPA network. Download speeds around 440k, which seems a bit slow? Dunno. Who cares! It's LEAGUES better than the crappy Samsung upstage i came from.
Don't forget to set ADC on using either the Network app from LG store, or through the MFG app in the Engineer Menu>Other Settings...
I think I tried messing with ADC while I was testing things out at the at&t tore, and the phone stopped receiving data (?), so I just left it on automatic, is that what you meant?
I'll check it out again tomorrow, right now the phone's updating to nodo as I get ready for sleep. I love this forum.
E900 or E900H
Hey edee1337,
You mentioned having a hard time finding the E900H, but never said which model you ultimately ended up getting. I wonder because it looks like you can get an unlocked E900 off of Amazon for around $360 (Seller:Yellow Deals) and I'm considering it for use with AT&T.
Which did you end up getting?
Thanks!
I used my sim-unlocked E900 both with Orange-FR and Open-EU ROMs in Canada for 2 months with a Fido SIM without any problem. With the Open-EU ROM I've noticed a more stable signal and MMS, but it worked quite well even with Orange ROM, only the MMS was missing that time, so I assume you can save a few bucks and stick to the E900 and set the AT&T profile on MFG App.
PS.: I am currently running my E900 on Brazilian "Oi" network without any problem too, just with the ADC turned on as there's no profile for any Brazilian carrier on MFG App, the same for Fido.
PS.: MMS works here too.
Thanks GolfVR6,
So when you look through provisioning options on your E900 you do actually see an AT&T one as well? If that's the case then I'm sure it'll be just fine.
Used to have until I flashed with the Open-EU firmware, but now when I try to access the Network Profile tool on MFG, the app quit and send me back to the Start Screen.
But I don't need to use this anymore as my ADC is working properly now.
Hi,
I did an unlock for this phone that i found in these forums. I have a generic tmobile sim card and put that in after i got the unlock code. from there i typed in the info and tmobile showed up on the banner.
well, i took the phone to a guy to trade for another, and now he's telling me he isn't getting any data, just phone and texting. of course, he's telling me this long after we made the trade.
is there any reason he wouldn't be getting data? or does an unlocked lg g2 only get edge speeds or something?
any help would be great.
My first guess is that he doesn't have the correct APN settings put in for his carrier.
You should let everyone know if the device is a stock rom, or another rom. Since the stock AT&T rom should not have the APN settings for Tmobile, but something like CM's rom should.
Worst case he should just need to enter the APN settings by hand, which isn't too hard to do. Other then that he could be in an area where Tmobile uses different bands for data then the AT&T version supports... that part I don't know how much it effects the AT&T G2, but has effected older devices going between AT&T and Tmobile.

thanks, and it is a stock rom, non-rooted. is that info available online? he says he went to the store and they tried to tell him it wasn't unlocked, or it's only half unlocked...people...especially people who sell phones.

Google would be your friend in this case, or his actually.
And can't blame them too much, they aren't given all the training that they should be given. They are just sales people, not tech trained most of the time. Every time I go into the AT&T store that I like, I end up talking unlocking & rooting for Android devices since they aren't told anything about that stuff. And I do let them know if they are truly interested to look here for more help.
Hey guys. I have and Unlocked and rooted i9505 S4 (at&t branded), currently running the Goldeneye rom. I recently switched to T-mobile and wanted to make use of their wifi-calling feature but even after installing the t-mobile sim card, I dont see an option for wifi calling anywhere.
can anyone suggest a way I can get wifi-calling on my unlocked/rooted at&t branded s4? thanks!
I think you might need to take it to T-Mobile store. From my understanding, it is only for SGH-M919. AT&T phones are not compatible, even if you switch carriers. You may have to flash a T-Mobile Touchwiz rom, not sure. If anyone thinks I'm wrong, feel free to correct me. :cyclops:

Thx for the reply rootnerd! yea thats the problem i'm having... I read that some people got it working with a flashed a T-mobile rom while others said they couldn't. So I was trying to see if anyone could shed some light as to which T-mobile roms with the wifi calling feature could be flashed via safestrap on an at&t phone, because I don't really want to buy a new phone from t-mo just yet

Yeah this is where AT&T users would know the answer. I currently have a T-Mobile S4 but I really don't think it's worth keeping Touchwiz just for WiFi calling. But everyone has there own perspective.
I have been doing research and searching these forums for a few days now, I'm trying to not be one of those people who ask questions that have been answered. But at this point I'm at the end of the road.
I bought a Sprint Galaxy S4, model SPH-L720.
I unlocked it using this method Sprint Galaxy S IV SPH-L720 SIM Unlock Method
Reverted back to MDC baseband and all that good stuff, just as instructed. It seemed to have went well without a hitch.
My question now is:
I want to buy one of these Verizon 4G Sim Activation Kits from walmart
Is it possible that I can buy one of those, insert the SIM into my unlocked Sprint S4, and have a working phone? I ask because I don't want to drop $50 if it doesn't have a chance of working. The instructions for this say that it will work with a VERIZON S4, but since my SPRINT S4 is unlocked, should that be okay?
I don't know much, but in my reading I found that Sprint and Verizon both use CDMA, not GSM. So I figured I had a better chance of this phone working if I go with Verizon because of this.
I am in the United States.
If you need any other information or screen shots please let me know, thank you for taking the time to help me out!!
EDIT: would it be possible to test it out, if one of my friends has a verizon phone under contract, and I took their SIM and inserted it into my phone?
Try it.
Like the guy above me said. Try it. One way to find out. Personally I don't think it would work. As the whole point of unlocking the sprint Gs4 is to use it on GSM networks. From what I know you have to flash the sprint phone to Verizon. Plus you WONT get LTE on Verizon because the bands are not supported. So you'll only get 3g.

thank you for the info! i'm just learning about all of this, so i don't have a firm grip on everything yet.
in the tutorial i used and linked above, the file I used with Odin was actually titled "S4 Flasher", so I believe I unlocked it and flashed it with this? Again, Im sorry, Ive tried searching and am just looking for verification if Im correct.
I'm not worried about LTE, 3G is fine really. Also, I'm not set on Verizon, I just want my phone to work, doesn't matter what network I'm using. If it would be "safer" or a better bet to get into a GSM prepaid, I will do that instead. I was just under the assumption (incorrectly probably lol) that since sprint is CDMA, that going to another CDMA carrier would be easier.
Cricket, Net10, StraightTalk, and AT&T etc are all available at the store I think if I go GSM
Again thanks for taking the time to help everyone!

I unlocked my sprint GS4 and went to Cricket. And I've been happier than when i was with Sprint (service wise). I have signal in 98% of the places I go to. Which is a HUGE improvement over sprint. And even though this phone only connects to HSPA+ which is capped at 3.5 Mbps its plenty fast for all my daily activities. So I recommend a GSM prepaid.
Hi all,
I didn't see anything from reading through the forum on using a Sprint HTC 10 on Verizon. It sounds like there's been success with Tmobile and AT&T.
So far, this is what I've found:
-Sprint HTC 10 should have all the LTE bands necessary for Verizon
-Sprint HTC 10 needs to be sim unlocked before anything can be done
-S-Off + root are required for any potential workaround for Verizon, as the appropriate radio needs to be flashed
How far off base am I? I am intrigued because I am on Verizon and I'd like to take advantage of the sprint HTC 10 sale that's supposedly going on right now. Thanks in advance!
I have the same question. I'm trying to jump on that but for T-Mobile. I'm just worried I won't be able to get the device unlocked.
Historically, Verizon and Sprint don't activate each others' phones. They're the two big CDMA carriers that don't use SIM cards, but activate by ESN directly. But there are always those who get lucky.
? anythin
I've been working on that recently. I actually want to be able to switch between Sprint and Verizon.
Sprint has to activate both the phone and the SIM. Verizon has moved to just using SIM cards. I've been able to move a Verizon SIM between devices and have everything work, even on devices that aren't official Verizon devices and even some that only support part of the bands Verizon uses and work on the ones they support.
With the HTC 10, I've been able to get S-OFF and unlock the phone myself since Sprint wouldn't do it. When I put in my Verizon SIM, it recognizes it but for whatever reason is unable to connect to anything but 1X Roaming (probably on Sprint but it won't say). Poking around in CDMAtool hasn't helped much.
I'll update this if I ever figure it out.
Any updates? I'm curious myself. I have the Sprint HTC 10 and am working on finding an MVNO that I like, some of the Verizon ones are tempting.

By perfectly do you mean volte and Wi-Fi calling are working for you? If so please point to the guide you used. I can't find where anyone using a sprint 10 has gotten those things on T-Mobile.
I would be surprised if a sprint 10 used on Verizon would have that work too but haven't seen any mention of it.

I unlocked the bootloader and installed ViperRom, picking the US Unlocked version as my device. I have working VoLTE, but not wifi calling. (Note, this is on Mint Sim, which uses the T-Mobile network)
yeah it would be great if someone could give a for sure answer to this. I've found a lot of post giving conflicting information all over xda and r/htc10 about this. I would love to buy a used sprint htc 10 (seems to be the cheapest version by far) and use it on a verizon mvno, but until I know for sure it works I' not going to do it.
