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

Figured out the problem the unlock did not take

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

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?

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.

There is way to do that, even punching in numbers if it works at all, which
won't, would not do it, at best it would only TEST your LTE band to make
sure it's receiving the signal properly.
Good luck!

I would go for lte/gsm/auto or wcdma/gsm auto
This way you always have chance for fallback to gsm when needed

No mobile data

After installing the latest version of pure nexus, I no longer can get my mobile data to work. Phone was originally on Verizon but is now on straight talk.

Did you check for a Verizon APN and/or its setting in mobile networks?

The only APN that is available is VZWINTERNET and it is checked.

Okay, but have you checked if the settings are correct? You can always flash the Latest MM radio to see if the issue is gone.

Which settings? I'm not sure what I'm doing. Kinda new to this.

If you press the VZW apn you get into the settings, compare these with the settings as shown on the VZW support page (Google).

I think I got it. Had to change the APN name from VZWINTERNET to TRACFONE.VZWENTP.
