[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!

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.

Unlocked, Rooted, No Data connection on Red Pocket att.mnvo

Greetings,
Purchased a T-mobile samsung galaxy s 4.
I unlocked it. Tried to use Red Pocket mnvo and there is voice but no data.
So I rooted it and removed the T-mobile data usage apk and still no data.
I have spent hours trying to get data to work.
What more needs to be done to get this phone to operate on a Red Pocket or Straight Talk mnvo using AT&T towers?
I use the same settings that work in my other unlocked android phones and no luck.
What APK is responsible for preventing data to work?
Do I need to flash a new customized rom to get this to work?
Has anyone else gotton an AT&T mnvo to work on this T-Mobile Samsung Galaxy S 4?
I am still within my return period so I need to find a solution or send this phone back.
I was orginally going to use T-mobile because they seem to promise 4g here but when I got it I find out there is only 2g speeds where I live.
My post won't help .. but this is very interesting as I am going to do the same thing.
I'll definitely watch this thread.
Is any one else out there getting Data connection with other carries after unlocking and rooting there T-Mobile Samsung galaxy s 4?
Any ideas on the cause of no data?

Try changing the network operator or the mobile network and see if your not using tmobiles instead of at&t...

You need to go to mobile settings and change the apn to the network you are trying to connect to also I think the phone has to be network unlocked
unlock isn't network unlock?

I did change the network to the one I am trying to connect to.
Also, I went to cellunlocker and got an unlock code. I thought that unlocks the network? The data has worked on all my previous samsung galaxy's after using the unlock code except for this phone.
Please HELP someone!

[Q] Problem with text messaging and hotspot after unlock

Hi,
I unlocked my AT&T Samsung Galaxy Note II 4.1.2. But every time I try to send a text message I get an error message saying message not sent. I'm not sure how to fix this issue. I'm right now not using the AT&T sim card but an international sim card.Please let me know if there is anyway I can fix this issue.

What network are you on?
Are you able to make phone calls?
Have you checked your apn's?

I'm on Airtel here in India. I am able to make calls and I have checked the apn. Whenever I turn on the mobile hotspot the message I get is "mobile data unavailable or invalid sim".
Have you checked the baseband of your radio?
If it was just the hot spots it would be the att tether blocking. But to confirm you cannot text either right?

Korea S3 (SHV-E210S)

I have the Korean s3 , I have made it connect to the Spark network here in New Zealand but I cant make any calls from it, I can use data and send SMS but not voice calls, is there anything I can do?
I got it working on the network by going into the hidden menu.
This is the HTC one m8 thread, so go to the s3 thread please

Verizon NOTE 4 ON T-MOBILE NETWORK HELP! ASAP!

hey i recently bought a note 4 for verizon and used it on t-mobile.
now it worked and i changed the apn settings manually. except:
1.) The phone would lose signal really quick in certain places and have the circle with a line thru it and it would take few mins, sometimes even have to restart phone to get service back ( i am in a 4g lte service area and it works fine on other devices)
2.) when i was in a call, the option to be on the internet DID NOT WORK. it would say check network settings or something of that sort.
3.) sometimes during a call even with full signal bars, it would hang up and say 'sim not found'
is anyone else experiencing this problem(s) also, or was it just a faulty device?
please any feedback, or insight would be appreciated!
Has it been more than 24 hours activated? Although not a note but her iPhone went from Verizon to t-mobile and she was having issues with data for about 48 hours.
I don't think its just your device (unless we both have faulty devices). I am having the same issues with my Verizon Note 4 on T-mobile network. When I am on a call that requires a keypad entry, it doesn't recognize that I pressed a number (same for voicemail).
My phone also loses signal and 4g in certain place (I thought it was tmobile at first but I was at starbucks with two other friends who had tmobile..they had 4g lte and phone service just fine while my note 4 had neither.)
I was wondering if it was a note 4 issue but haven't found many forums that discussed these issues specifically for verizon note 4 to tmobile users. Please let me know if you are able to find a solution to this problem.

You are correct. I have a Verizon Note 4 that is having the same issues. I'm considering trading this for a T-Mobile note 4 but I don't know how to do that other than craigslist....too bad there is not another way....
