Did the stock ICS connect before? Because this phone has the 1700 band for 4G 
and T-mobile doesn't have that band working in all areas, so you get only 
edge/2G in those areas. Link for coverage in the US: http://www.airportal.de/

Yes I was getting 4g Lte with stock ROM. I have att 4g Lte available at my 
house and it worked well with stock ROM but cm-10 is not.

I followed steps in porting thread and I think Lte is now enabled but I'm not 
in a Lte area at the moment. It does now show Lte in network mode. Thanks for 
your help.

Just to follow up I can now connect to Lte but I have no data service on Lte. 
Phone works but no data.

You must go into apns settings and choose the preset ATT LTE pta apn, it will 
not be set by default. After all this, LTE will work.

Hi,

I just put Slim on ("Slim-3.1.0-20130523-0805-UNOFFICIAL") my Burst.
I put in a T-mobile data-only chip.  When I go to APNs, there is no checkbox, 
just a blank window. "Choose a network operator" just spins ("Searching..."), 
and eventually
reports failure. I have "Data enabled" checked.  "Network mode" seems to prefer 
"Global", "GSM", or "WCDMA" or combinations.

In "widget buttons" I have "Toggle LTE" and "Toggle Mobile Data" checked, and 
in Network modes I have "2G/3G Only/3G+2G".  When I pull down the Notifications 
drawer, 
I have LTE and _^v_ highlighted/on.   Am I missing something?

Not familiar with T-Mobile but I don't think APR should be blank. Something not 
right. Try researching T-Mobile APR settings.

I found

http://forum.xda-developers.com/showthread.php?t=2240233

but when I choose APN "Save" after entering the fields, the APN screen remains 
blank, with no checkbox for the new entry.  I tried both epc.tmobile.com and 
fast.t-mobile.com for the APN. Ideas?

May not be supported in slim but not sure. I just tried creating a new APN 
using cm10 And it let me save it.

Try posting in the Burst discussion thread on xda. Maybe someone there can help.

I have the exact tmobile problem, and my sim is a normal sim, which means I am 
suppose to get calls from it. However, all I get is emergency call only, with 
the same blank APN screen, and couldn't save anything there. I wonder if that's 
the PA Rom problem?

Update... I installed 29Jul2013 versions of AOKP and PA on my Burst Presto 
P9070.  Saving an APN fails in them, too.  (AOSP crashes every few seconds, 
too; I had to use a USB keyboard to type in the values.)  Current Slim fails to 
initialize, crashing after the "Skip" SIM button.

Is the phone unlocked? Did the sim work on the phone while it was still on the 
stock rom?
