[Q] ATT Note on Tmobile network

Hi
I have a ATT Note 2 with a t-mobile sim in it with ATT rom/modem/etc. The HSPA worked for like 2 minutes and never worked again. 2g works fine.
Has anyone gotten 3g/3g+ working one ATT note 2 on the tmobile network?
I know note works but couldnt find an answer for Note 2.
Please advice!
Thanks

^^^^^^ 2nd this.
ready to acquire GN2 ATT from local CL. but since i use t-mo cheap 5gb data plan, i am not sure how to benefit the plan. just a thought, you said HSPA worked for 2 mins (or so..) ? did you do any browsing/data usage and get result ? or just monitor the signal bar switching from H+ to E ?

I did a speed test and got 5mbps download. I also have the 5gb plan. There must be a way to get it to work!

Check and make sure your apns are correct.

Has anyone tried flashing a t-mobile modem?
Sent from my SAMSUNG-SGH-I317 using xda premium

I did - it gave me no service

Did you tried flashing a T-Mobile ROM??

yes didnt work either..

@ vish :
another shoot in the dark, do you think it has a relation with the phone being unable to toggle to 3G / UMTS mode ? will you please flash the t-mo radio back and tried :
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect.

so with jedi ROM x 6.1.2, 4g signal stays intact ? can you please do speedtest & post it here ?
btw : this 4g signal, supposed to be H+ in t-mobile ? or is it just UI issue ?

Sorry for the late reply - i tried flashing tmobile model and I got either bootloop or no service. Even with the sim card out.
Any other ideas?

Are you sure you are in a refarmed area? Cause if not you will ONLY get EDGE

^^^ what he said. T-Mobile is refarming their network to be compatible with AT&T's 3G frequencies but only in certain cities right now. Check their website, it tells what cities. They may be testing in your area. Otherwise you'll only get edge because the note 2 can't do what the note 1 did. It's an exynos thing.

Has anyone tried this SIM card release thing to force 3G on t-mobile network on a AT&T Note 2 phone? did it work? or did I misunderstand this post to be a solution to getting 3G/4G on tmobile network?
Please help

Only edge will work. Get a t mobile device or switch to att.

[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.

LTE Connection problems

For those of you have LTE connection issues when in the past LTE worked fine I want to share what I did and it worked. I am not in a Spark area and after getting the update from Sprint I lost LTE connection at work. I previously had LTE a 100% of the time at work. I noticed that a lot of folks on the Sprint forums were having the very same issue. After researching with Sprint to solve my problem (They were no help at all), and the combination of things I read here on xda (I can't find the forum So I take not credit for this) I want to share the solution that worked for me.
1. Call Sprint and obtain your MSL code
2. In the phone dialer enter ##3282#
3. press LTE and enter edit, Enter MSL code
4. Click on LTE, then bands 26 and 41 and disable both of them
5. Phone should reboot and LTE should work as it did before
If someone would be so kind if I can't find the threads on here I would like to link them and give credit were it is due.
I just wanted to share what worked for me.

Just a note if you get a profile or prl update that you did not initiate you will have to turn off bands 26 and 41 again following the steps above.

Disabling bands 26 (800mhz) and 41 (2500mhz) seems counterproductive to the gains that Sprint Spark is supposed to bring. I'm guessing it's probably region specific to those having LTE issues where disabling these bands "fixes" whatever issues you're having (maybe Spark is not fully deployed, etc). I'm not having these LTE issues by the way, and LTE coverage here in NYC has improved to the point that i even get LTE in some underground subway stations.

That's the exact problem, the roll out is far from nation wide. So if you are in a non spark area, the phone constantly seems to search for it. My battery life significantly decreased on ZVC. Once I shut off those bands, my LTE was much more stable and battery life improved greatly.

SOS. my phone stuck on EDGE

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?

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
