I'm coming to US from with my mobile bought in europe. It is a Samsung galaxy ace GT-S5830 so it works at 850/900/1800/1900 .
I've found in the compatible phones list only S5830i S5830m which have a different processor.
1) Will mine work in US on T-mobile network?
2) at what speed? 3g?
3) can I use either a prepaid or a postpaid plan?
many thanks!
