[Q] your experience with at&t

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.

[Q] AT&T LG G2 unlocked to use on T-Mobile Carrier Rom/Root Questions

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.

[Q] Putting D801(tmous) variant on ATT?

So I was looking over the difference between D800 (ATT) and D801 (TMOUS) and it seems that the reception difference is D800 has an LTE band 5 and the D801 has an 3G band of 1700. Whats the practical difference in reception? Seems like att is starting to grow band 5, and 1700 is tmobile. I travel to some remote areas and I think tmobile works there and att struggles (not sure at least it did 2 years ago), but do like the idea of freely switching between the two without having a tradeoff. will probably start with straight talk for att but will switch to the tmous if i cant get service where i move.
Please share thoughts on the best strategy...
thank you

Hi.

From my own, uninformed research I think we will be fine taking the T-mobile LG G2 (d801) to AT&T.
Looking at the information below taken from Phone Arena, the LTE band 5 isn't in all AT&T LTE phones

Going off of this research I've ordered the D801 but It is possible I can turn out to be wrong.

This explains it more

I'm currently using the Tmobile version on ATT and haven't had any issues so far. The only problem I'm having is it appears there is substantially less support for the Tmobile version.

The D801 CM maintainer was out of county apparently and I'm guessing he held off on uploading everything since he's been gone for a couple weeks and didn't want to push something that would be broken for weeks by chance. We'll start seeing a good bit of roms in the coming weeks and by everything moving to KitKat we'll be in as good of shape as any other device since our devices are plenty similar to each other.

LG G2 d801 (t-mobile) with AT&T straight talk activation help...
I just tried to activate my factory unlocked lg g2 d801 with straight talk with at&t. I set my APN up for the at&t network and used the at&t sim card that came with the straight talk bundle. Now on the lock screen it says invalid SIM card.
What do I have to do to make my phone work? Thanks in advance!

I borked phone flashing a T Mobile based ROM on my canadian G2 (since they both are the D801; by personal research I've observed the D803 works as intended on my canadian D801). I will try later today to flash yet again another T Mo rom on it, but this time I'll flash back the stock kernel. I'll report back.
Just to play it safe, I'd reflash your stock kernel... that way it won't act funny all of a sudden along the way.

Thanks, but I haven't rooted my phone and don't really intend to unless I absolutely need to. It's factory unlocked right out of the box.

It turns out Verizon was holding things up. I'm so happy I'm leaving them.
I tried setting up my APN, but now I can't download or view any media or picture texts in messenger or hangouts. Any suggestions?

LTE on AT&T with D801?
I can't seem to find a clear answer on whether it's possible to get LTE indication and speed on a D801 (TMo) used on AT&T.
Tech Support is giving me the "we can't guarantee data speeds on non-AT&T-branded phones".
This thread seems to say a TMo-branded phone (LG G2 in my case) CAN be provisioned for LTE:
http://forum.xda-developers.com/showthread.php?t=2506590
Most other threads say no, or there's no conclusion in the thread.
Can anyone give me the straight answer and tell me how to go about it? A way to get past the stone-walling AT&T techs?

I have H2O which uses AT&T's network but only HSPA+ and not LTE but the phone sees AT&T's LTE network when searching for networks.
In this thread there is a screenshot of a T-Mobile phone getting LTE indication on the AT&T network.

Along with a lot of confusion about why his phone was working on LTE. As a relative newb to this stuff I couldn't make any sense of it.
Also in that thread was this comment:
T-Mobile devices support ALL AT&T and T-Mobile bands, except LTE Band 5 (used by AT&T in a few rural areas). What's wrong is AT&T turns off LTE for non-AT&T devices. You have to call them up and give them the IMEI # of an AT&T-branded device (even if it's not yours and even if your SIM isn't in it/you don't plan on using it). They don't check after that.

So it might be possible to "trick" the carrier into allowing LTE?

Guys, I'm not getting data and sms on my unlocked d801 on at&t. Can anybody share APN settings for at&t that work?

I got my unlock tmo g2 working on at&t with LTE, mms, and Microsoft exchange email after some effort. It's also connecting to my 3g microcell.

Sorry for hijacking but anyone moving from D801 to ATT can share their APN Settings. Cant get internet to work to save my life!

Lg v35 lm-v350awm at&t gsm

Hello!
I found this V35 bidding on ebay which according to the seller's title it is AT&T unlocked.
Before i buy it,i want to know if i can use it in Europe..will it work for 2g,3g and 4g networks?
Do i have to flash another rom for it to work on my network?
Thanks in advance!

I bought an AT&T branded phone on ebay. It was advertised as unlocked. It wasn't and did not work with a non AT&T sim card. If you end up in that situation, it is easy to buy a sim unlock code from a service like codes2unlock.com. The phone works great seemingly everywhere! It can be rooted too if you're into that.

Oh thank you very much for this info.
Basically i don't really have it with rooting,but i was thinking of just flashing a new stock rom that could remove all AT&T bloatware.
I've read somewhere that this is possible to do via a ULM version kdz rom.

Korean V35 user here. I'm also from Europe and the phone works just fine in my country. Though, Korean software is annoying because it thinks it's constantly in roaming and is very conservative when switching networks, but I know the hardware is good because a rescan always finds me a 4G network. Anyways, I'm sure that flashing ULM rom will fix that, I just don't have the time needed to mess around with that atm.
Enjoy your new phone

It is so nice to hear that you can use it in Europe.
It's a really wonderful and hardware strong device,and on the other hand so beautiful without all these ugly notches.
It is a real shame of LG that left European market out..they always find a way to shoot theirselves on feet.
And hey..i don't own it yet,i just watched it on a bid,but thanks anyway for the wish)).
And for sure i will keep looking for it until i find one i like and can afford the cost of course,because extra cost for tax and import charges is about 70 euros more than original price.
Thank you for the infos anyway!

4g calling on US996?

I'm currently using a US996 (the "real" factory unlocked version, not the US cellular one), and was hoping to do so for as long as possible. Unfortunately, my current carrier is AT&T and it seems that they will be dropping support for 3g calling early next year- which I am told will render my model unable to place or receive phone calls.
Anyways, I have *heard* that my device will be supported if I switch to T-mobile, but this comes from some googling a year or so ago and probably some less-than-reliable sources.
I was hoping to get a run-down on what my options are if I want to retain both my current device and ability to make phone calls come 2022. I currently have an unlocked bootloader + LineageOS installed on my phone as well, and would prefer to maintain that rather than having to use a locked-down carrier ROM

I have seen mixed reports from users who got VoLTE working on T-Mobile for their US996 while others did not (I'm still on a Sprint MVNO, so I won't be able to test this myself until T-Mobile completely takes over the network). But what's certain is that only the H910 can get VoLTE on AT&T (they keep a whitelist that determines which phones can get it), and LineageOS on pretty much any LG phone will likely never have it working.
So, at a minimum, you'll have to at least go back to a stock-based ROM if you plan on using a V20 next year on any carrier in the U.S.

I am not XDA savvy so forgive me if this is not what you are asking.
I have US996 factory unlocked ,I am on stock 8.0 and use Net10 which is ATT and do calling with LTE. which I assume is 4G.

What OP is saying is that the calls on AT&T and its MVNOs for a US996 are actually done through 3G/HSPA and not LTE, unlike cellular data. AT&T's own H910 is the only V20 model that can make calls through LTE (VoLTE) on their network. Once AT&T turns off the 3G networks early next year, calls will no longer work on the US996 and any phone that's not on AT&T's whitelist.
You should be able to see this on your phone: When making a call, the LTE icon will not stay up, indicating that VoLTE is not working.

Oh nifty this phone becomes more and more an issue. So now I ahve to add this to my plate. Seems like it will still be a year. OK but the US996 has LTE so why is this still a problem? Why wont it just use the LTE band?
Please be kind I do not know all the acronyms or how any of this all works.
Cant the US996 also run on Verizon?

Because of its whitelist I linked in the second post, AT&T actively blocks any phone not on the list from using LTE for calls (VoLTE = voice over LTE).
As for Verizon, they blocked direct activation of the US996 starting in 2018. You will see that entering your phone's IMEI number on Verizon's website will give you a message saying it's not compatible with their network even though it is perfectly capable. It may still work if you insert an already-active Verizon SIM card in there, but I don't use Verizon, so I can't say for sure if that still works.

Wow, talk about a way to force new contracts and phone sales. I never had a phone not be useable for PHONE CALLS. I guess I am grateful for the heads up as I was not aware and Net10 did not inform me of such things. I bought this phone because of specs and it was a removeable battery . But it seems this phone just was a pain from the start, with the screen issues, and the company claiming they would upgrade to Pie and never did.
T-mobile did not have useable coverage in my area when I tired it several years ago. So I really do not know what is going on since they now have Sprint.

Not sure if you're still looking at this thread but i have a v20 us996 factory unlocked and a G6 us997 factory unlocked and they BOTH get VoLTE on Red Pocket Mobile AT&T mvno. Calls DO NOT fall back to 3g or 2g and data stays active while in calls.
