[Q] No 4G LTE Data on Galaxy S3 - Sprint Samsung Galaxy S III

When the S3 first came out, I purchased a brand new one, and set it up for my wife on Boost Mobile using an Incognito as a donor. We used it that way for about 18 months until the Iphone came out on Boost. My wife wanted one so we bought one during the holidays and I took the S3.
Using DFS, I restored the original MEID, did a factory reset, then a prl and a profile update on the phone. I installed Cnexus' 4.3 factory sprint ROM without KNOX (Build #JSS15J.L710VPUCMK3) and it activated just fine on RingPlus. Since I'm using the unlimited plan over there, I have more than 1gig of data to use on a monthly basis, but cannot make 4G work. I'm in Houston, BTW so I have 4G LTE available.
The only way that I can make data work is to go into the data menu and select hybrid mode in the IOT Hidden menu. if I select either of the LTE options (LTE+CDMA+EVDO Modeo or LTE Only Mode), data does not work at all.
Am I doing something wrong, or do I need an APN update? I did use AlpineMan's APN update at some point during the Boost days.
Any help is appreciated. Thanks in advance.

Can anyone direct me to a compatible sprint APN? I think that's the only thing left I know to try.

i've got the APN's, ill send em your way once i find them on my computer.

Activate Metropcs data on activated Sprint phone possible?

My Sprint network services suck, and I still have my old metropcs account active.. so I was wondering.. would it be possible to activate metropcs data on my 4g touch activated for sprint?
Anyone? Not trying to steal service as my metropcs account is still active. I can use the modem mac from my old phone if needed,

... but note in that thread says 4G won't work. Might help you though.
I already know I wont get 4G, but working 3G sure would be nice. I want to try and set it up for testing. I am currently using forced roaming with the hacked verizon prl, but if I keep this up I will eventually be kicked from Sprint.
Yes, you can flash metro pcs onto your Sprint ET4G. I have mine flashed. However, I can't get mms to work. So, 3g works, text, talk...no mms. I had someone from Craigslist flashed it for $40...

Hey, I have been at this for some time. I'm very confused about some things. I currently have the Samsung Epic 4g Touch (Galaxy S2). To my knowledge my SPC is now set to 000000, and most the QPST settings (OR CDMA settings if you prefer) are set and correct.
I was wondering if there's anyway you can shoot me a response or PM with how to get everything working. I don't even have data at all. I can't seem to figure it out.
Doesn't Metro use Sprint towers?
If so, I doubt you will notice a difference in speed/signal strength!
I have also unlocked my phone and have set my setitgs correctly via QDMA and as far as I know MetroPCS has stopped updating ESN numbers unless its a Metro phone. any news on this?

Please help LTE stopped working not sure why!!!!

Bought my phone form Rogers. LTE was working fine.
Was going to USA and paid an online company to send me unlock code.
Used it and went using Tmobile which only has EDGE data.
Just got back swapped back in my SIM From fRogers and can only get EDGE speeds.
Tried reboots rmoving SIM card.
Also made sure settigns were correct for Rogers APNs and also that toggle was on for GPS/HSPA/LTE.
To no avail.
Briefly, I toggled on and off the apn setting from ROgers LTE to tethering LTE and low and behold it seemed to work.
But now it is back to stuck on EDGE and nothibg I am doing can help.
Can this be a byproduct of the unlock?
Is my LTE faulty?
I s there some hidden menu where perhaps a setting can be changed for a fix?
I am depserate as the alternative is to return the phone and they are on backorder everywhere now.
There is no lte on tmobile yet. Second the tmobile note 2 has dormant radios that will only activate the lte capability by software update.
Im going to research your problem a little more ill send you a pm as to why it isnt going back to lte functionality if I find out something first...

appreciated!
I have a Canadian note 2 that had working LTE.I had it unlocked via a code emailed to me then next used it on tmobile at edge speeds.
Since returning home i cant get back onto data speeds above edge despite reboots.Simcard/battery pulls.
I ensured my network and apn were correct and that in setting under mobile the toggelchoice for auto including gsm//hspa/LTE was selected.
Are there perhaps some deeper settings via dialer code than might be able to turn back on the hspa/lte radios?

[Q] Trying to bring this to Boost Mobile, but no data connection

So my father handed me his Galaxy S3 from Sprint and explained that he wanted it switched over to Boost Mobile because he had been having contract difficulties. Nevertheless, I've sucessfully rooted it and switched over the ROM to the stock Boost ROM and had begun changing over the APN data. I'd found a copy of the Boost APN settings and was able to restore that .xml file to the phone to get standard phone calls and text messages to work on the phone.
From this point forward is where things get complicated. I can not seem to get data and mms to work and have tried everything to get it to work. I've tried the ##72786# and the only thing it seems to do is reboot the phone and require that I re input the PTN and MSID. The phone itself is running KitKat currently and has the NDC version of the stock Boost ROM. Any insight as to how I can get this phone ready to go with at least 3G? (LTE's not really a thing here) Thansk!

PS The network name is called Samsung for what it's worth. Not sure if that has to do with anything.

You can't simply change it over to Boost by putting a boost rom on it. You have to call Boost and get them to switch the phone over. You don't have data because your phone isn't on a phone plan . Call boost and get the phone activated and you'll be good to go.

I'm so sorry but I may have under-explained this situation. I grabbed the ESN and MSID from a donor phone that we had laying around, and wrote them to the S3 using a combination of DFS and CDMA Workshop. The ESN from the donor phone was then registered to Boost Mobile and everything went smoothly until I tried to grab for data. This would be the problem that I'm facing. Calling boost might work, but I'd have to be careful what I say lest they be on to my evil schemes (lol). What I believe it needs is a data profile update, since I'm not too sure I've programmed it in ##DATA# properly. Alas I'm trying to look for a workaround so that I can get into the phones menu and connect to the Boost Mobile Data network, but I'm kinda lost as to direction.

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.

Straight Talk data issues with custom roms using 4g LTE Verizon sim

Greetings everyone!
Signed up so that I can hopefully help someone else in need with their LG G3 phone using the Straight Talk 4G LTE Verizon sim card.
After many hours of flashing roms and trying out various things, it turns out for some reason other variants of the stock roms like Bliss Pop, CoudyG3, and Skydragon will not work with the data. I can still use my phone and make calls and i can still get text messages and even pictures sent through text messages, but for the life of me data would NOT work.
The only rom that did work again was the Jasmine rom. To my understanding it works pretty close to the stock verizon rom that comes with the LG G3. After the flash, BOOM! Everything worked and data came back to life.
I noticed the APN settings is very very different but this rom wont let you go in it to see it's settings. Surely there is a way to import/export the APN data to push on over to another custom rom? Just weird that after putting this specific custom rom data happily worked again.
BTW, if anyone tries to activate a verizon lg g3 with straight talk, be careful. Though their stupid website said that the phone was already registered with another tracfone provider/service, I was still able to get the phone to work. If after entering your MEID/EMI or whatever the numbers are and the straight talk website spits it back out at you, CALL straight talk. I got screwed and used up the network access code which somehow got lost into oblivion, but turns out that they themselves can manually add the Verizion 4G LTE sim card with the network access code card. (I bought the 4g LTE sim card package from wal mart). As long as the phone is in good standing, it will work!
Thanks. Hope this helps someone else out trying to get it to work with straight talk. I will try and see if there is a way to export this APN setting. I was told by straight talk that you don't need an APN set, but i think they are lying.
Peace!

Back again,
Happy to report im using skydragon Rom with straight talk. Turns out you do in fact need to set the apn in the settings. Just add this apn
acct.tf.gw6.vzwentp
This is the apn for the Verizon 4g lte sim card when you use it. I didn't have to reset the phone but now data works great.
Hey question. I have a Straight Talk S3 currently running CM 11 kitkat based rom and things work great but I found other roms I want to install one of them being a Pac-Man custom rom but I have no data. I have a Verizon CDMA 4G LTE sim coming in acouple days just need the apn settings. Could anyone help me out with this? Thanx in advance for any help.

Surely it is the same APN setting as above. Try it out once you get your Sim card. Also, that S3 being a different phone may pick up on the access point names when you try another rom and set itself up, but if data is still not working, then try that APN I posted on the first post.
Also, be careful that you are actually connecting at LTE speeds as long as your area has it. Flashing to another rom I was only connecting at 3G. Turns out that once I tried another rom, you have to set the preferred network to LTE, then give the phone a reset. It took it a moment after reboot, but LTE finally showed up.
Depending on your phone, there are other settings to be set in it's hidden menu settings using the phones dialer. Just google around.
Hope this helps!
