I have a T-mobile pre-payed SIM in my i545 Verizon. Phone works and data but only edge data. I am on a T-mobile partner network (I Wireless). If I install the same SIM in my Windows Phone I got with the SIM, I get 4G.
Any ideas?

Have you been in the ServiceMode menu? Dial *#27663368378#
If not, dial it, choose 1 umts, then 1 debug screen, then 1 basic info. Does it say LTE RRC:CONN, Band 4?
If not, you might have to select the band preference.
