Thanks for the info. I don't fully understand the relationship of the different bands, and 2ilk continue watching for YouTube videos forThe phone has Bands 1, 3, 5, 7, 8, 20, 38, 40 and 41
AT&T uses Bands 2, 4, 5, 12*, 14, 17*, 29, 30, 66
TMobile uses Bands 2*, 4*, 5, 12*, 66, 71*
(The bands with the * are the primary bands)
So unless you live where AT&T or TMobile use Band 5, the phone won't work on them. (In other words, it's not made for the US market.) And I didn't even look to see if there's an English ROM for it.
