[Q] Virgin Mobile SPH-L710 LTE Issue - Sprint Samsung Galaxy S III

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.

[Q] new ROM... my old 4g is all 3g and my old lte is now all reg. 4g. {HELP}

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?

[Q] ATT Roms on T-Mobile network?

I currently have ATT service with my S3. I'm running the Intergalactic 3.0 at the moment and I absolutely love it. However - I just switched to T-Mobile. I want to keep my current phone and sell the free S3 they gave me so I don't have to deal with losing any information or anything like that. Can I get away with this on the ATT based ROM? IIRC T-Mobile and ATT run on very similar networks/frequencies. Any advice would be helpful here. If worst comes to worst and I have to use the T-Mobile provided phone, can I flash Intergalactic on it as well or do I have to choose from the T-Mobile ROMs on this site?
Thanks to everyone in advance.
You should be able to add the proper apn for t mobile. You also may want to flash one of the t mobile radios.

I just switched from ATT to T-Mobile. I have an ATT SGS3 running Task's AOKP. APNs filled themselves in when I put the T-Mobile SIM in and everything works flawlessly.

Strange. I unlocked the phone, I was able to put in the SIM card and the APNs filled themselves. I was able to make calls and texts but unable to use internet. Any idea here? Using Intergalactic 3.0
To clarify - no internet at all. No Edge, GSM, or LTE

No idea. I'm not getting LTE, but I do get H+ and haven't looked into it yet. Maybe it's the ROM? I'm on Task's newest release.

Strange. I went back and re-registered on the network through the settings and now it's getting 4g, just no LTE. At least it's working though!
Edit: Kinda. It worked for a minute then I locked/unlocked the phone and it didn't want to work any more.

Virgin Mobile Galaxy S III on CM11 M8 LTE issues

Hello. I apologize if I'm in the wrong place, I'm new to the forum. I'm having an issue with my 4G LTE. Whatever I do I cant seem to get my 4G working. The best I can do is get 3G. Can someone either tell me how to fix this or link me to a fix? I've been looking every where but I can't find anything definitive! I have a Galaxy S 3 L710 under virgin mobile. Thanks!
Look around the forum for the "universal VMU APN fix" and flash it. That did the trick for me.

do you know anyone else that gets LTE on Virgin where you live? and are you in a know/unknown LTE area? and on CM11 you can't do a data refresh code that you can do on stock....what i would say to do is flash back to stock or to Wicked X 8.0 or Tribute Rom and see if the LTE problem is still there and if what i mentioned doesn't fix said problem i would read up on what @flamepanther mentioned that fixed the problem for him

Straight talk galaxy s3 Verizon version

I have the straight talk galaxy s3 that runs on Verizon towers...I have my contract 4G sim in the phone running a Verizon rom and everything does work but it roams everywhere I go and I don't get any 4G (disabled by straight talk). I was wondering if flashing a sprint rom would help at all? I seen the sticky saying not to flashing any rom from another carrier but I've flashed dozens of different roms and all has been good except the roaming. Anyways, just wanted to see if I could get some help here. Thanks in advance
What would it take to enable the 4G on this phone?

You might have to configure your APNs, or, if you haven't for a long time, you might need to update your modem, since you don't get that sort of update with custom ROMs. On my Virgin Mobile phone, I have to flash an APN fix on every new ROM, otherwise I just have 3G.

The straight talk version I have runs off Verizon towers and they have 4G disabled but the phone is suppose to be 4G enabled. The apn fixes didn't help. I'm wondering if this would need something like cdma workshop.
Ah, I see. Yeah, if the 4g is blocked on multiple ROMs, you'll need an app to fiddle with the sim card. Hopefully it's not hard blocked (a physical switch or the card is incapable of it even though the phone is)! I'd try to contact Straight Talk and/or see if it works on stock. If you're trying to get 4g without straight talk knowing, well, I don't know much about that, but CDMA workshop or something similar might be worth a shot.
I was thinking cdma workshop would be the answer but I don't know where they have it turned off. It sucks being confined to 3G when the phone is 4G compatible and straight talk will allow 4G on there Verizon network now.

at&t 4G LTE Support

Hi,
I have an unlocked version of Fire Phone and have flashed the almost latest version of the Cyanogenmod ROM. I am using at&t wireless service but it seems that I just cannot use LTE. Based on other information I think the phone supports all the bands at&t is using. The network the phone is using is HSPA. I tried changing settings in the phone but it did not help. I searched carefully using related keywords but have not found anybody talking about this, and I wonder whether this is something too simple to ask or nobody else has ever encountered this problem. I want to know if there is something I can do to use LTE.
Thanks.

I have seen some issues about CM based ROM's and ATT LTE. Did you have a full LTE signal and good data speeds on the stock ROM before you flashed the CyanogenMod ROM?

Thank you for your reply. Unfortunately, I had already flashed CM before I switched to att so I do not have information about that. And currently I am not quite willing to flash the phone back to the native fireOS just for this because HSPA still gives good data speed...

Have you checked your APN settings and verified that it is setup correctly to use ATT LTE? Also, was this phone ever used on ATT before with the sim card you put in it? If not, then what will have to happen is this, I think: I found this excerpt which I believe is what will have to happen.
You WILL NOT get AT&T LTE on you phone unless your account is first provisioned with an AT&T LTE Phone. There is NO WAY around this. You must buy/borrow an AT&T phone that has LTE capability, put your SIM in that phone, and let the system provision your account for LTE automatically. This is NOT something that customer service, or a store clerk, can do for you. Once your account is provisioned for LTE (you will know because the LTE indicator will show up on the phone), you can then put the SIM card into your Fire Phone. At that point, the device will automatically select the "phone" APN, and you will get LTE (identified by the "4G" indicator).
Hope this helps
