[Q] 4G No Longer Working? - AT&T Samsung Galaxy Note II

Okay, so I'm currently running Jedi X 6.(something, the newest AT&T Rom). Now, I was running version 6 before with no problems. 4G was working fine (we recently got 4G in my area.) The tower is right down the road and I've always had full bars when on LTE. It seems that since, or at least within a few weeks of flashing this new Jedix6.whatever I can not for the life of me get LTE working. This isn't an "I can't tell if the icon means LTE" thread. I went into my "about device" and my mobile network type is always on HSPA:11, UMTS:3 or HSPAP:15. I tried flashing the stock modem in the "One stop shop" thread, I also made a new APN with all of the correct information for AT&T LTE. Neither worked. So my question is: is it the ROM? If so, what ROM definitely has it working? And if not, any suggestions as to what a fix might entail? It's probably a little selfish but I bought a phone with LTE capabilities and I'd like to use it. Any input is appreciated!

so you using the PTA apn? Cause a rom wont stop you from using LTE... So your saying recently 4G was turned on in your area? cause AT&T Calls HSPA+/3G they call it 4G and LTE is called 4G LTE.

Also how do you know LTE is not working? Speed tests? No 4G icon? No/slow data?
Just curious, because I have noticed sometimes when in 4G LTE areas my data is slow/unusable with full bars and legit 4G LTE connection.

i dont know whats in your market area, but in mine the LTE has been off and on the past few days

Okay, as I stated in the OP I have been using LTE 4G. About 2-3 months ago they put 4G LTE in my area which is about an hour from Cleveland Ohio. Also I frequently go to Cleveland on weekends and they've had it for at least a year, so I know it's not just the towers in my area, as I used to get LTE there and at home, and now I don't get it in either place. I know it's not LTE anymore because I'm getting the H+ symbol along with the info from "about device" that I put in the OP. If my phone was connected to 4G LTE it would say LTE:14. I hope that helped clear the air of some things... Any other ideas? So a rom won't affect it at all?
Also this is the APN I tried to put in:
Name: ATT Phone
APN: Phone
MMSC: http://mmsc.mobile.att.net
MMS proxy: proxy.mobile.att.net
MMS port: 80

LTE APN?

What is the stock APN for LTE on the Note 2? I flashed a custom rom but im used the Telus option so I can use Network Selection.
I know I can google it but When I google LTE apn I get the pta apn which is not what came on the phone.
If LTE works with the 'phone" APN then what is the pta apn for?
Only APN I have. Works fine on LTE.

Are you referring to forcing EDGE or HSPA+ only? ATT modems do not allow this. I am very interesting in getting this to work on att?
Can I ask which rom you flashed and which modem? Now that you got the LTE APN how is performance?

No Im not refering forcing to GSM/WCDMA. I was referring as I did not have the LTE phone apn.
And I dont have an issue switching between GSM-Edge/WCDMA-HSPA+ at all on my phone....
And I dont know how LTE is yet, Not in an LTE area just near them in 2 directions.
I flashed my note 2 with CleanRom. I like it. Seems fast enough and I like the features. The thing that bugs me is that my network status icon always shows as either 4g or H+. Never LTE and I wonder if I'm actually on an LTE network, or just the enhanced 3g. I get about 6 mbps down and 1 up according to speedtest. Not bad, but I've seen people in my area getting 15 down and 8 or 9 up. Granted I'm on AT&T and they were on t-mobile. But my impression was that t-mobile wasn't going to be LTE until sometime in 2013.
I've set my APN to the settings in this thread. It's possible that I just won't see the LTE icon.
Any thoughts?
Do you have the N7100? If so I dont think that supports LTE.

Clean Rom uses an international base which means the icons are different. AT&T LTE = 4G, you can also verify which network you are connected to by going to Settings > About Device >Status > Mobile Network Type. If you are connected to LTE, it will show you LTE:14.

S3 i747 ATT unlocked + CM 10.1.x + Tmobile = No LTE?

I have the ATT SGH-I747 with Baseband I747UCDLK3. The phone was rooted, CWM 6.0.3.1 Touch was installed, and has been running CM 10.1.x nightlies for a while and now is finally running the latest stable release.
When LTE was enabled by TMobile in Atlanta recently, I went from having a solid/working 3G/H+ data connection to no data at all. It is as if the phone would persistently try to connect to the LTE network and fail. It would also try to drop back down to 3G/H+ but have no working data connection ever since the day TMobile turned on LTE in Atlanta.
As a workaround, I set the phone to use Preffered network mode as: GSM/WCDMA and the Data has been working fine on 3G/H+ but of course not using LTE.
Is there any way to get LTE working in this configuration? Could this be a problem with the Baseband or is it CM 10.1.x?
TIA for any information you may provide to help me fix this problem.

Correct me if I'm wrong, but T-Mobile uses different LTE frequency than AT&T.
Finally got it working, 4G!!!!!!

I have finally gotten it to work. The problem was that the APN information necessary for LTE was missing.
I created a new APN manually with the information from:
http://forum.xda-developers.com/showthread.php?t=2236735
Name : T-Mobile LTE
APN: fast.t-mobile.com
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS Protocol: WAP 2.0
MCC: 310
MNC: 260
APN Type: default,supl,admin,dun,mms
Now the phone is working properly at 4G speeds, speed tests show over 25Mbps down and 10 Mbps up.
Thanks for the info!

Hey, I have tmobile as my carrier and an unlocked at&t S3 i747. What baseband/modem are you using? I can't get a strong signal at all.
weird issues
So I have an issue. I have a i747 and have T-Mobile. My internet works fine. Sometimes. If I want to brows the web I have to first make a call And then my internet just starts to work. Usually... Can some one help me out.

Getting Straight Talk LTE on sim purchased before LTE announcment?

I've had StraightTalk, using AT&T towers for just over a month (using an AT&T GS3). This was prior to their announcement about LTE becoming available. Everything pointed to needing a new sim card to take advantage of it. Yesterday, I noticed the LTE icon in my status bar. At home I get around 17 mb/s, and at work I get only like 1.5-2 mb/s.
I first noticed the icon on the CM 10.2 9/23 nightly. I'm running the most recent 10.2 nightly, and I'm still getting LTE.
Has anyone else had LTE pop up, when using Straight Talk using the old sims?

I have had straight talk for about a year and a half, long before LTE was available on straight talk. I tried to switch the old apn to the lte with no luck. I would just not get data. I ordered a new sim and intended to have my number transferred over to it. I called customer service this morning with sim in hand and asked to be upgraded to lte. They transferred me to someone that could help and he took about 10 minutes and I did not even need my new sim. They did something on their side. I asked if I would need to change the apn and they said no the old one would work. That turned out to not be true. I drove into town as I do not have lte at home and I had no data. I switched to the lte apn rebooted and boom LTE! So it seems now if you have an old att sim that was HSPA only you can call and get it switched over. I was shocked that I got right though and did not get put on hold forever and this worked. Maybe they hired more customer service reps, or I just was lucky.

This is correct they can provision your old sim to work on LTE as long as unused the new apn. It is hit or miss when u call there customer service odds are you will get someone who exactly knows what they are doing 1 out of 10 lol

The above posted APN settings are exactly what I am using and LTE seems to work fine. Mind you I purchased the sim card in Nov. of 13. GS3 I747 4.1.2, downgraded to 4.1.1 root injected, sim unlocked then flashed to Hyperdrive 16. All is well with LTE on this end.

I think it might depend on the service area. Where Im at I only get H+ but a hundred miles away in a bigger city bang it auto switches to LTE and hello speed, goodbye battery.

FIXED! - No LTE

Hey guys. I'm kinda stuck here. I am getting no LTE service on my phone at all. Of course those idiots at straight talk keep saying im provisioned for it but nope, not getting it. I tried everything I can think of from factory resetting to apn settings and nothing. When I go into my network it bounces between HSAP and HSPAP but no LTE. I live in an LTE service area and was getting LTE up to about a week ago but then suddenly it was gone. Any ideas as to what I can do?
Can ask what are your APN settings?

I don't understand what's goin on. It just doesn't work anymore for some reason. And ST troubleshooting is non existent. All they tell you is to put in those apn settings and it should work. Well it isn't dumbasses!....lol
Also port :80 . I have straight talk too. Your apn looks right
My wife has the Optimus g and her LTE is working just fine. WITH the same APN settings! The last thing I remember doing was going through the hidden service menu but I didn't change anything in there. There is nothing you can change in there to make your LTE stop working. I know with some phones you can but not with the OGP.

Ok guys. I got the issue resolved. I used this method here - http://forum.xda-developers.com/showthread.php?t=2351041
The only issue I had was for some reason I couldn't manually edit the build.prop. I had to install JRummies Rom Toolbox Lite and that did the trick.It's so nice to have my LTE back!
Thanks for the link. Always liked to manually set to 2g or 4g when lte was weak. One reason I always installed custom roms and didn't stick to stock.

Personally I don't worry too much about it. Being on stock with this phone gets great battery life. So no need to turn off the LTE to conserve battery.

att s3 on ST with issues

ok, sgh-i747. fresh NJ1 rooted flash done yesterday. using phone on straight talk with att sim. supposedly lte capable. at work i can pick up 2-3 bars of lte no prob. runs great. but this morning the phone automatically switched from lte/gsm auto. to wcdma mode on its own. it did this three times in a row inside ten minutes. then all good most of the day. however this afternoon it did it again twice. sticker on phone say i727. phone info states the same. so what would cause a gsm phone and gsm simcard to suddenly go wcdma for no reason? i do suspect a bad sim. ive heen having connection issues as well. at home signal isnt the greatest but on att i always maintained 1-2 bars of 4g. using the straight talk sim it will connect to 4g for a few minutes maybe, and then drop to edge. if i am not on lte, it will not stay on 4g. jumps to edge. its not the phone i dont think. this morning i put my sim in gf phone,same exact phone. entered same exact apn settings, rebooted, and waited. after a minute or two it dropped to g then to edge. her att sim in her phone usually maintains a steady 4g at 1-2 bars. never drops. her sim in my phone works flawless. same thing. steady 4g at 1-2 bars. how is that? doesnt the phones radio determine signal strength and what network type to use? it seems my thinking is wrong. everyone says sim cards have nothing to do with signal but after seeing my ST sim react the same in someone elses phone, i gotta think different. my settings are the most common ones

i made a few different apns with different type combos. and one with no apn type. each time tho i deleted the apn, then rebooted, then entered settings, rebooted again.
would all the rebooting and different apn settings and messing around mess up a sim card? ive had this card about two weeks. seemed to work really good for a few days. and of course tech support is no help. also, was trying to research ST sim cards to see if some were better or some problematic. found nothing for mine
