I have a European model of Samsung Galaxy S7 Edge (SM-G935F), 32GB version.
It is a SIM free phone, not locked to any particular vendor. I am aware of region lock, but from my understanding it should be OK, since I have been making calls for a few months with it in Europe.
According to GSM Arena, these are the bands supported by this model:
LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600),
8(900), 12(700), 13(700), 17(700), 18(800), 19(800), 20(800),
25(1900), 26(850), 28(700), 38(2600), 39(1900), 40(2300), 41(2500) -
G935F
Currently I am using EE carrier in the UK, supporting bands 3 and 7.
AT&T in the states should support bands 2, 4, 5, 17.
My assumption is, because my phone supports these bands, I should have no trouble using LTE in the US?
Thank you for your help.
