Hello guys. I am really interested in this phone, or the Compact version. I am on Verizon in the USA but one of my contracts is expiring soon, so I was thinking of jumping to AT&T and getting this Sony (since I am assuming there will be no Verizon version?). I travel all over the US and the world so I cannot be stuck with T Mobile's weaker US network. So, a few questions...
Can somebody confirm which version of the Z3 will work with AT&T in the USA, on all bands that any other AT&T phone would? In other words, I don't want to get this phone if it won't COMPLETELY work on all 3g and 4g/LTE bands in the US. I see there are several Model Numbers and there is some confusion on which models work on which carriers.
Also, do all the versions support the same GSM networks for global roaming?
I would greatly appreciate any info you guys have to clear this up. Thanks!
