I unlocked my LG G2 for Tmobile and am getting no data with AT&T sim card. I put APN in but its not working.
Can someone please tell me how they got theirs to work on LTE?
Thanks!
BUMP... Anyone??
I'm using my T-Mobile LG G2 on Straight Talk (on the AT&T Network) and got data after creating an APN with Straight Talk's settings. To get LTE I also changed System Settings -> Tethering & Networks -> Mobilie Networks -> Network Mode to GSM / WCDMA / LTE auto (I previously had it to WCDMA since my previous provider did not have LTE). For AT&T I found this:

Got this error message when using a TMo SIM in a Verizon G2. I've only seen one thread about this for the G2.
Verizon G2s are SIM unlocked, right? So it shouldn't be a problem? I can put the TMo SIM in a TMo branded S2 and get full bars. I even tried the same SIM in a Verizon Galaxy S3 and got full bars.
I'm on VS98012B
As a follow up, I went into available networks and this time, TMobile at AT&T show up. I tried setting it to WCDMA and GSM but it wont register on the TMobile network.
This is a location that I can normally get LTE.
The VERIZON model is GSM unlocked. Says your on 12B so you should be good. You should be able to just pop and go. I don't have much experience with it but you would have to select GSM in the Network Settings.
Hello all, i have a question regarding an Australian Telstra Galaxy S5 with att service. the phone works with voice and text but has no data or mms. i have added an apn from my sim card in a galaxy nexus that gets me edge service. i have found band selection in the service menu but non seem to make it any better. I'm sure LTE won't work but thats ok. as long as i can get 3g at least. do i need to flash say the att s5 modems? if so how? i have the modem file and another already extracted from the att firmware. thanks in advance.
Samsung Galaxy S5 SM-G900i branded telstra
i think firmware ANE1 4.4.2

Using a foreign handset on a system will never give you perfect coverage. That is by design, as both Samsung and carriers want to lock you in, not make it easy for you to change carriers. Or do so without buying a new phone.
The specs for your variant suggest that it has full coverage on ATT's 3G bands and partial coverage of their LTE allocations. You don't need an ATT modem, just make sure that your firmware is recent - which it will be by definition, as the S5 was only released a few months ago.
Unfortunately you didn't provide much detail, in particular whether you were roaming or a regular ATT customer. Things that you might check in general, that your phone doesn't blacklist any ATT MCCs (roaming restrictions). That you have the correct APN information and that your ATT SIM is properly provisioned for LTE.

Thanks for the reply. I figured it out. In service menu, I was picking compatible gsm bands. Back to network screen in settings, had it on gsm/lte only. That was giving me edge. Read more into wcdma and used network mode wcdma/gsm. That gives me H or H+. I know I won't get lte but with that network mode and another apn, I'm satisfied with the end results.
It sounds like you inadvertently blocked coverage with your previous settings. The default setting is automatic band select which should have worked fine.
Glad you figured it out in the end.

Yeah. It was the apn that was hurting me. Default it used the wap.cingular apn. I put my sim in a galaxy nexus and used the apn that gave me. Plus changing network mode. Thanks though!
I'm getting a Verizon phone soon used. I understand I can get everything working on my att sim card but it would be HSPA+? Just change the settings in network mode GSM/umts is this correct?
Hi all,
I've been having a Sprint Galaxy Note 4 that is unlocked. I bought it unlocked already. My mobile service provider is T-Mobile. I have an unlimited plan with them. The issue is that the Note cannot connect to LTE network. The only option available for me to access the internet on the go is the GSM/UMTS option under the network mode settings. Using this option my phone can only connect to a 3g service that is painfully slow. If I try selecting the CDMA or LTE/CDMA option under the network mode settings the Note will not get any service at all as if there was no sim card inside of the phone. Therefore I can only use the GSM/UMTS option. Is there a fix for this or am I stuck with 3g service on this phone? Please ask me questions if you have any that will help me get to a fix. Thanks :fingers-crossed::fingers-crossed::fingers-crossed:

I believe the LTE bands in sprint CDMA/VERIZON CDMA are different. they are not compatible with T-mobile because T-mobile required completely different LTE bands and they are locked in sprint phones and they cannot be unlocked.
If you have N910V/N910P You will only get HSPA/HSPA+ 3G/3.5G with T-MOBILE/AT&T network.
My best suggestions will be you can swap your sprint with T-mobile note 4 because N910T has more LTE bands unlocked then any other note 4 models actually more bands then international models too.
After unlocking the phone everything works just fine, including all the Google services (hooray!), but it gets only 2G speeds on T-Mobile LTE network in the USA (4G setting in the phone is enabled).
The APN is T-Mobile US LTE. However, if I go to Settings > Mobile Data > click cog on top right > Data plan settings it shows the phone carrier still as China Mobile in Beijing.
Does this mean that the SIM is locked to China Mobile only? If yes, why is the phone working, although at 2G speeds only?
Is there a way to make sure the phone is SIM locked? I’d like to avoid spending $30+ for an unlock code to find out it’s still not working.
If you have the correct APN settings I think it's the basebands using different frequencies that are not compatible with the p10 lite.
