My son is using a 920 on Tmobile that I got through Rogers. It has been mostly working fine, but occasionally no MMS or delayed texts, that kind of thing. At the same time, I got a major update to my Galaxy Note II that turned on the LTE capabilities. When I looked at the APN on the Note II, it was new and different. Plugging it in to the boy's 920 seemed to work just fine. We are not in an area with LTE yet, so I can't vouch for whether that works or not.
If anyone else wants to try it:
The apn name was "T-mobile US LTE" with address fast.t-mobile.com
MMSC is http://mms.msg.eng.t-mobile.com/mms/wapenc
MCC 310
MNC260
APN Protocol IPv4
I didn't see anyplace to put in the MCC or MNC
Let me know if it works for others, and whether those in LTE areas of Tmobile get the LTE service.
