No data, anywhere. on T-Mobile PLEASE help - Xperia Z Q&A, Help & Troubleshooting

First experience with t-mobile... I have absolutely no data unless I'm data "roaming" which allows me 50mb. I've tried changing settings, talking with t-mobile for days...I have 3g/4g next to my full signal bars. I'm really angry about this since I'm paying extra for unlimited data. I can't find help threads anywhere and everyone else I know in this town with t-mobile apparently doesn't have the same issue. Please help

Check your apn settings or your sim card.

T mobile tab unlocked getting horrible service on att.

Like the title says. T mobile tab flashed over to euro rom to allow phone access.
I put my att sim in and it says att in the notification bar says att but i get little to no service. If it does get edge it dissapears a second later. Could this possibly be because of a bad unlock if that exists.
A side note. I am using a new 4g att sim in the tab would that make a difference

You did not mention if you checked the APN settings. I am not sure if the TMOUS AWS band is the problem on ATT.
Sorry, yes i did check the apn settings. But would the tab still show att if it wasnt unlocked. Maybe my unlock didnt take.

And just to add some info. When i first put my sim in it took a while to get service then it started to junp around frequencies. Edge then gprs then hsdpa and now nothing

You do relize that Edge speeds will probably be all you get for data FYI.

You will not get 3G since att 3G operates at a different frequency than tmobile. However you should be getting edge.
I am having the exact same problem with the unlock ? How did u get it to work exactly

At&t Note with non data connection

No data connection here.
Just got my Note about 6hrs ago and had no data connection out of the box, just WiFi.
Anyone else with same or similar issue?
Now, I am using my Captivate simcard though I dont see how that could possibly cause this, but anyway...
Thanks,
Ryan

have u checked if your apn settings are correctly entered in wireless and connections settings? apn should be configured with the at&t config for it to work

Yep, AT&t pta is ticked "on" and then all the options inside under that are greyed out.
I even tried Reset to Default but that didn't work either.

Maybe try asking in ATT Note forum?
If its the at&t branded note you need a lte data plan & and sim

Blocked APN

I have a sim provisioned for a tablet that I've always used in phones for a second data-only device. The Note 3 seemed perfect for this. However, when I go in to add the "broadband" apn it will not saved. I can put anything else in apn field and it will save but not broadband. Anyone ever seen anything like this and know any roms that would work?

You went to mobile networks and tried to set up your APN there?

Wifi Calling

I have an ATT Device a Verizon device and two tablets.
All Samsung except for the Nexus 7.
What's the best way to achieve calling calling through wifi? What's the best app?
I'm aware of Skype and Google Voice I guess.
Is ATT ever considering turning this feature on like T mobile and Sprint?

They dont need it, simple as that. The average user has no trouble getting an AT&T signal inside their home. T-Mobile is another story, due to their high frequencies which do not travel far.
I guess I never thought of it like that. But that makes perfect sense.
T mobile and Sprint have the worst signal lol

LTE issues.

Is anyone else finding that their phone will not connect to LTE?
I did *#*#4636#*#* and tried to change it from WCDMA Preferred, but it does not allow me to do so.

Southern Connecticut area here. Is yours set to WCDMA preferred as well?

Mine is set to lte/GSM auto and will connect to 4G lte when I am in a city with it. Montana has only a few cities with lte and mine is surprisingly not one of them.

It happened to be a bad SIM card. I went into AT&T and they put in a new one. LTE popped right up. Problem solved.
