[Paul Park1]

is lumia 1020 rm-875 associated with AT&T?

since my current lumia 1020 att unlocked phone is not working properly on familymobile, (hotspot wont work unless i use att..)

is rm-875 (international version) totally not associated with att?

i want to make sure that this does not have an att rom

oh, and rm-875 works on tmobile or family mobile with 3g right?
(i only need 3g)



thanks guys
