Long time lurker here, hello
I bought a Galaxy Note 2 for AT&T off CL. I got it for a good deal. When I bought it, the guy had it running on Net10 and had a custom ROM (cleanrom) on it. I put my AT&T sim into it and the radio was wonky. Would keep dropping signal and only get on EDGE or GPRS. So I reverted it back to stock by flashing the stock image via ODIN. I even flashed the newest AT&T radio and now it gets LTE, but it is still off and on.
I'm at my desk and after I power it on, it takes a couple minutes to grab signal and gets LTE. Keeps it and then drops it again to one bar and is on EDGE. I put the same SIM into my S3 and it grabs onto LTE almost instantly and stays on it.
What am I doing wrong?
Check APN settings to ensure that you only have one listed.. Then edit the "APN type" field and change it to this..
default,admin,fota,mms,supl,hipri,internet
Make sure to select menu key - save or it won't save. Then reboot phone and how does it react?

I`m pretty sure if he ODIN`ed right it would be the RIGHT APN settings....
But you need to make sure you DID a factory reset before and after odin sometimes when flashing from a non stock rom and flash with a stock rom sometimes stuff will still be there if I didnt wipe everything.
Also APN`s would not cause phone call nor service drops, dont need an apn to get service or Phone calls.
Hey everyone!
So I picked up a tmobile s4 to use on ATT since I read it was the most unlocked due to bands / bootlocker. I unlocked it via the method described on this site via the debug menu.
Popped in ATT sim, everything looked fine initially.
1. I'm only getting 4G in an LTE area. device hasn't picked up any LTE anywhere yet.
2. When I go under "Network Mode" and select "LTE/GSM/WCDMA (auto connect) the signal dies out and it always reverts back to GSM/WCDMA"
3. I've called ATT a few times and triple checked that I'm on an Android LTE data plan, so that's not an issue. ATT techs suggested it could be a device issue and maybe I should take it into their tech center.
4. Tried to set up ATT Visual Voicemail, that failed also.
So can it be a Sim issue? Maybe something on tmobiles side? Since device was never active on their network. A lemon S4?
I've run out of options
Any help would be appreciated.
TIA!

The main end game fix was that ATT had my IMIE # incorrectly set. Once they fixed that my LTE was a go!

Not sure. All i know is when I put my t-mobile sim in mine I only get edge no 3G as I do know the bands for HSPA are not there but not sure about LTE
I had my att g pro on tmobile and got lte, when i get home i will put the tmobile sim card in and get the apn i use. That's all i did last time (insert sim and put apn manually)

I only got edge at first too but I know I live in a refarmed 1900 MHz area so I went under settings to network operators and searched networks manually and chose tmobile rat:14 when it gave me my options. Now I get 4g umts- hspap. I use wifi while home and after I leave sometimes it will revert back to edge. I went into the hidden menu but I didn't see how to select band prefence anywhere so im lost on how to get lte to work.
I know at&t and tmobile use the same lte band I just cant figure out how to select it to make it work. Try selecting setting>networks>tethering and networks>mobile networks>network operators>search networks. A few different tmobile ones should pop up with rat:2 rat:3 and rat:14 underneath. When I selected rat:2 it only stayed on edge but all other options gave me 4g.Hope that helps to at least get you 4g working.

Ok that would be great if you can post the complete apn your using. I have the fast.t-mobile but maybe another part of mine is incorrect...
I am pretty sure for LTE to work on T mobile, you have to make sure the apn is set to fast.tmobile.com. Your Sim might be setting it to the default epc.tmobile.com, which will only give you HSPA+.

I appreciate the help but for some reason it still wont get lte. I have tried all the different apns I can find and after I enter it if it still only goes to 4g then I reboot. Is there anyway to select lte only from any hidden menus or an app or something?

on other phones, the following menu lets you pick what you want your data to be: *#*#4636#*#*, then pick lte/gsm auto from there.

I tried but it doesn't have the option to change the network mode. I actually just edited my build.prop to enable network mode under settings and it worked!!! I finally got lte by choosing lte/wcdma option. When all the options appeared my lte appeared to be shut off .So all I had to do was turn it back on. Huge thanks to MrDSL for the help.
After changing my network mode to lte wcdma my phone kept saying roaming notification off at the top of the status bar and all I could use was data ( lte at least) and wouldn't make calls and the network mode menu actually disappeared. So after putting in a at&t sim card and rebooting my phone about 20 times the network mode menu popped back up and allowed me to change my preference to gsm/wcdma/lte and luckly its working perfect now.
I have a g pro on tmobile but for some reason theres a few places where I don't get 4g or lte and the phone loosses signal for a min or two then I get E is this happening to someone else ?

Yes. It happens to me on my way home. 2-3 times. Live 35 mins from my job I go from a city to rural area 2 times. Not refarmed as of yet I get the nasty red x
Since i changed a new rom(cm11) for my unlocked i747, I could not receive any hspa+ internet(I am using h2o). at the begining, i thought it was because of the lost imei, so i fixed it, but it was not working. then i opened *#*#4636#*#*, and selected wcdma perfered, it changed to h+, but about 1 min later, it turned back to Edge. if i select wcdma only, I can use h+ 1min and then no more signal even edge. also cannot make phone call and texting. i dont know why. the APN setting is right. and anyone tells me what should I do. thanks very much!

i had tried some other rom. i even regressed it to the originally official rom. it was will EDGE. I wonder the possibility is that some important files has lost. but i didnt find any solutions.
These seem like pretty routine questions but have you checked to see if another phone has the same reception problems?

My friends has a g920p and wants to enable some bands so lte from telcel can work now he has only H+. Can that be done. I know that the s3 can with some magic. Thanks

Just put the phone on automatic in mobile network settings and set up two apns one for hspa and another for lte but make sure the lte apn has the bearer option set to lte the other just leave it how it is.
Didnt get it my friend.... here in mexico we use same apn for 3G or 4G LTE. We just need a sim v6.x and will get the lte bands.

I know how to do this, but you would need to have the MSL number, if you don't then Google idoneapps, this guy sells an app that unlocks phone and extract that number.
So i need the msl number so how can i get it. Friends phone is already unlock.
Enviado desde mi SM-G920F mediante Tapatalk
MSL number is needed to edit data settings in sprint hidden menu. Install shortcut lite master and then search for PST, launch that application. Then look for ##Data#menu. You'll see there if your LTE is enabled or not. If it is not the only way to enable it is having MSL number.
Hidden Menu
there is no need for app for shortcut. Go to setting and go to Activate this device. Phone will load some info then look at top right for MORE. Click on it then click on PST. This will take to hidden menu,
To get LTE working all you have to do is create two separate APN's one with your regular APN settings and another that is identical APN settings but on the "Bearer" setting put it on LTE and you're good to go also make sure your phone is set to automatic and not gsm / umts

what you stated here is correct. but have you tried it yourself?
I did, but there issue with send text messages. incoming sms works, outgoing - no.
there is no need to set to automatic. in service menu there is point where you can set preferred network type LTE_GSM_UMTS., but again, sms does not work.

No clue maybe do ##72786# it will reset the phones modem settings and it will nag about activation again and relock the phone but I did it since I can unlock it myself again and never had an issue.
Weird thing is that my phone after unlock it wanted activation popup and then it actually went through and it went away with my T-Mobile sim.

Ok found something out for some reason if you do not get LTE after setting it to Automatic switch to LTE/CDMA let it reboot and Reswitch it to Automatic reboot again then LTE+GSM_WCDMA should work.
Do you mean in service mode select cdma/lte then reboot and then go back to service mode n select gsm/wcdma/lte? Because ive been trying that fkr hkurs since reading your post lol. If this works your a beast . We need a gsm rom for this phone tho

George, do you have a legit way to get lte working on our device ? I haven't seen any proof from anyone claiming lte working on att or tmobile.

hmmm, been in the same boat with T-Mobile and a G920P, with only 3G being picked up but after switching it to automatic, it picked up LTE! Thanks for the poiter. However, have you been able to get MMS enabled or working as I seem to have issues with that and not sure why it isn't downloading the messages. Not sure if I need to give T-Mo a call and get something enabled or what. BTW, how did you manage to make that annoying activation screen go away as the moment I got it unlocked and popped in my sim card, it can't ever activate, but works fine though
any one succeeded in unlocking bands
Has anyone had any success enabling additional bands on a Sprint S6? Basically the bands it comes unlocked with are useless for Europe 4g and would love to unlock bands 3, 7, 20, 28, however 3 & 7 would be enough.

Same here. seems to me Samsung does not give us open source to edit Exynos settings. As I'm aware, our phones' hardware is capable to get those bands
