Unlocked D850 for TMO now I can't get LTE with AT&T, TMO LTE works fine. I have both AT&T and TMO sim cards . I'm running Stock KK rooted . I did upgrade to lollipop and still no LTE on AT&T, but lost root so I downgraded back to KK via LG Flash Tool.
I tried a few different APN's with no luck. IDK any help would be appreciated

Which APN's did you try??
I tried the nxtgenphone that was the default one when I put my AT&T sim in. Also tried "phone", this one I get 4g but not lte. I also found one that was either "pto" or "pta" I think it was "pta" this one I get no data at all, same with the "nxtgenphone"

Hello,
I bought the phone from Kijiji and it is stated as unlocked. When I put in my Virgin Mobile sim card it shows I have full bars and connected to the Virgin network and di not ask for an unlock code so should be unlocked? Now with the full service bars I have no data connection indicator and everything is on and the APN for Bell/Virgin is inputted in it already. But I cannot send or receive anything or use any data. Says network error.
Any help?
Thanks,
Jay

Are you sure Virgin is a GSM carrier? I'm pretty sure they are CDMA only..

Virgin mobile no longer supports CDMA. They are 3G and 4g lte only now.
I have tried the virgin radios and different Rogers and AT&T. Even telus and tmobile radios but none worked.
When I put the SIM in it says its on virgin and connected but no 3G or lte logo and can't send or recieve texts or use anything with data.

I'm not convinced, are you sure they're off CDMA now? You need GSM fot texts and on this phone in general. 3G and LTE is not the same.

This is virgin mobile canada. They only have 3G and LTE service here. I have had the S3, iPhone, and many other GSM phones no problems. Recently the Note 1 LTE. Not sure what is going on. It doesnt say to input an unlock code when I put in the SIM so it must be unlocked?

If if shows the carrier name and doesn't ask for a code then it's unlocked. Did you try Bell radios? Virgin Canada uses the Bell network and does indeed prefer lte and hspa to cdma as you said.

Try the ones here. It seems like it's something else though. Try wiping data & cache & dalvik cache in recovery or doing a factory reset in settings. Try flashing a stock JB rom in Odin or any other rom for that matter. Try flashing a rom in recovery. Just be aware that JB roms need JB modems. JB modems are backwards compatible with ICS and GB roms. The two official JB modems are RUXUMA7 and UCMC1. There are JB modems from other devices that work on our phone as well, but you'll have to find them yourself as I don't remember.

Ok I tried everything you mentioned in the post. Still no luck. Tried the ROM you are using on your i727 that you have listed in your siggy. I really like it but still just comes up with "BELL" and no data and cant text or do anything.

That's a problem. I really don't know how to help you. One thing you can do is compare Virgin Canada's hspa & lte frequencies with Skyorckets default ones and see if they match.
These are the default frequencies on the Skyrocket.
3G Network - HSDPA 850 / 1900 / 2100
4G Network - LTE 700 MHz Class 17 / 1700 / 2100

Jay, I had to unlock my phone myself with I bought it. I use Fido in Canada. After upgrading to include data for the first time, I had a similar problem. Everything looks fine but I had no Internet. I advice you to put your sim card in a Virgin phone already running with no problem and see whether the issue was is with your plan. Sometimes the carrier screws it up as well.
Hello, just upgraded from a Galaxy S4 on T-Mobile to an unlocked Verizon HTC One M8 handset. Popped in the sim, I can send and receive text, data on HSPA/3G mode but not one LTE or Global mode (anyone know why this is? I'd like to be able to use t-mobiles LTE and not just HSPA/3G), get the usual "sim unknown source" stuff. I am wanting to flash Skydragon.
My question, is there anything special I need to do before/after I flash these, since I'm using a different network than what the handset was originally supposed to be on? Maybe I need to flash different radio? This is my first time using an unlocked phone, previously all my phones with custom ROMs were on the same network as the handset variant.
Otherwise, would I just update to the latest 5.0.1 OTA update from Verizon, root/unlock bootloader, install TWRP, then flash Skydragon, and I'm all good?
Edit: Well, further reading seems to indicate to me that it turns out verizon M8 devices already updated to 5.0.x are still not able to be rooted at this time?
Thanks for the help
Sir I purchased a new unlocked S6 Edge ( 925A) at&t device from abroad to use in india.
The guy told it's fully unlocked and it support any sim card. Buy when I checked with Indian Sims I am getting only 2g signals .. I am not getting 3G and 4g signals..
When I checked for network selection mode settings it's missing in the settings.
No software OTA update is available. . I think it's also disabled.. when I checked the device status it is in "custom"..
So if I flash a stock ROM with Odin will it lock again ?
Do I need to unlock it again.. ??
First check the model from bootloader, if its actually a att variant then you can flash a stock rom too make it work as normal, but if its some other variant then get back to this thread again.
Its surely an at&t Variant of Samsung Galaxy S6 EDGE.. its model number is 925A.. which is only available for ATT..
Its baseband version is G925AUCU1AOCE
I purchased this phone as fully unlocked from UAE but in india when i start to use it i came to know that its not taking 3G and 4G signals .. but 2g Signal and Data services are working fine..
I got the phone in rooted condition without any Boot animation of At&t. Since its rooted i am not getting any official updates.
I am also facing many software bugs.. from different apps..
So really want to flash the phone with a new stock rom for using it..
I have some doubts about it please clear it..
1) if i flash it with an official att stock rom will it lock again for att network ?
2) can i remove the att boot animation after flashing with stock rom ?
Sent from my SM-925A using XDA Free mobile app
Providers in India use bands 3, 40, and 41 for LTE. The AT&T S6 Edge is only compatible with band 3.
I doubt you'd be able to flash a different ROM, and even if you could, you still wouldn't have compatibility with bands 40 or 41.
Firstly Thanks for your reply.. i know that S6 Edge at&t only support Band 3 LTE cuz it's a FDD LTE supported device.. in my country here providers are using both TDD & FDD LTE bands for LTE..
In my region "Kerala" at presently all the providers are using Band 3 which is compatible will my phone. But i am not receiving any LTE and 3G signals..
My friends have different unlocked phones from T-Mobile they are not facing any problem..
I am still doubt the flashing ROM.. i am going to flash the stock rom for at&t.. it's the only official rom available for my device.
It could be an APN issue. Make sure the settings are the same as your friends are using. Beyond that, I have no idea.
Nothing Wrong with the APN.. cuz i am using 2G data without any problems.
We have same APN for all 2G ,3G & 4G..
I think its the problem with my software..
I can't switch between LTE/WCDMA/2G because that network mode selection option is disabled or not available..
I am compelled to flash a new Rom..
I don't have any other options.
I own a good phone but i can't use it . Really sad about it..
for sure people here can help you more on this

My friend got a used SM-G920R4, has AT&T, and wants root. I want to get the AT&T stock firmware to put on it, then root it. The sim works once AT&T settings get added to the network list, however mobile data doesn't work. He is running Android 6.0.0 and has an unlocked bootloader.
