Hey guys! this is my first post on here and i need some help... I have an AT&T Samsung Galaxy S3 i747 and i rooted it, and put CM10.2 on it last night, everything went on fine however i used to have 4g everywhere and 4g LTE at my office, i noticed that CM10.2 doesnt support 4g for the S3(i dont know why...), so i cleared everything again and i put SlimBean build 5 on it.. still, my data is degraded one level.
my friend has the exact same phone but on verizon and his is working perfectly fine with SlimBean 5, i did use the AT&T version for the files on my phone. my Network Mode under system network settings is set to LTE/GSM/WCDMA and my APN is set to ATT (wap.cingular).. i tried the APN of ATT LTE (pta) and nothing changed..
any help on this is greatly appreciated!
again its an AT&T Samsung Galaxy s3 i747
did you reboot after you changed apns? have you tested the connection with an app like speedtest.net?
What is the icon by the signal bars? 4g? H+? Have you tried flashing the latest JB modem?
Greetings!
I have a Galaxy SIII (SPH-L710) with Virgin Mobile (US).
I have been able to change the firmware and load CM 10.1.
Unfortunately, I cannot connect to Virgin Mobile (Sprint) 4g LTE. In order to get my mobile data working at all, I have to change my network mode from "LTE/CDMA/EvDo" to "CDMA/EvDo auto". I cannot get 4g to work at all. Has anybody else been able to get this working?

I came from regular sprint on an iphone and 4G LTE coverage was very spotty, and therefore rather unreliable. I have not seen it connect to LTE yet but i'm actually not surprised by that. However, getting any kind of data connection has been very difficult, so far. I'm rather concerned and looking to see if i need to flash to a new baseband version or something because poppa needs at least a 3G connection.
i've tried in and out of airplane mode with 50% good luck...so, there's that too.

ok just a quick update, i've been trying a few different modems/basebands from this post:
http://forum.xda-developers.com/showthread.php?t=1787677
LJ7 was not holding a 3G signal well, and would not connect to LTE. I moved over to MC3 and that actually deactivated my phone off Virgin. As a result, i had to go back to the virgin stock rom and re-activate. It was painless since i found this wonderful post here:

I'm currently running the MB1 baseband, but haven't been able to test it yet - going to provide some updates once i can test some more.
I'm having the same issue but on Boost

Did the MB1 baseband ever work for you? I am curious, as I have not yet been able to get 4G working on a custom ROM on my Virgin S3.
What KitKat ROM are you running that has 4g that works?
I am currently on Vanir and cannot get it to work. I have tried different APN, different radios (GA02 and GJ04). I have gone into *#*#data#*#* and turned on LTE. I have gone into *#*#4636#*#* and I am on GSM/CDMA auto (PRL). I have gone to networks settings and selected LTE. NONE of the settings stick.
I had 4g working at one point on CM 11 Playfulgod edition but I can't remember exactly what I did to make it work. So I am looking for other Ting users that have 4g working and what ROM you are using.
Hey mates
I have samsung note 10.1 2014 LTE (sm-p605) which is mentioned as a 4G tablet in back of it and a 4G sim installed on it.
it shows that this tablet has LTE. BUT there is a problem, I can not see LTE or 4G in network mode that I can select.
I rooted my p605 and did all 2 solutions that I could find in this page : http://forum.xda-developers.com/showthread.php?t=2762554
But no one of these ways did not work for e and I could not get LTE on my device.
I also install CyanogenMod 11.0 on my device ( Here ) but I could not still get LTE and also I tried this lovely lollipop ( Here ) which is one of @Schischu great works, but i still could not see LTE on screen.
I need your Idea or solutions to understand why there is n LTE on my sam.
thnks in advance
Good afternoon the issue I'm having is I have brought from T-Mobile over to MetroPCS (same company I know) my Samsung GSIII (SGH-T999). I rooted and Flashed a CM11 Nightly Build(not stable) (CM_d2lte 11-20150301) that would work on the MetroPCS network for non-MetroPCS Samsung phones. I also don't have any of these issues mentioned in their development Wiki: http://wiki.cyanogenmod.org/w/Known_Issues_page_for_d2lte
Everything works except for I keep getting 3G instead of LTE using the fast.tmobile.com apn because the metropcs apn wouldn't work for me (although its a branded sim card from metro) and SMS I was only able to send out SMS during the first day of a fresh reinstall of CM11 Nightly Build and cleaning of the cache and system during recovery mode. The only way i can receive or send sms is through Whatsapp....
I've searched through the forums for any threads that have had a similar issue like:
http://forum.xda-developers.com/showthread.php?t=1875760
But I don't know if that will work with my nightly build and phone model because this is for Sprint GS3s and mine is from TMobile, don't know if there is really a difference.
TL;DR:
I Have rooted and flashed a CM nightly build for MetroPCS on a T-Mobile SGIII (SGH-T999) but SMS doesn't work and signal icon only says 3G apart from saying T-Mobile network but that can be because I'm using an APN for t-mobile. Main issue is not sending or receiving SMS.
