I am interested in buying this phone too (U.S. user here), and someone in another thread said that SIM cards purchased from
SmartTalk are technically on the AT&T network.
So does that mean I can just buy this phone out of contract for $450 from AT&T's site and then just pay month to month on Smart Talk?
I really want to get this phone, and I am currently a T-Mobile prepay customer. SmartTalk seems good to me, for the price ($45 for unlimited everything)... but if I have to switch to AT&T proper, I think I'll pass on the Lumia and just get myself a Nexus 4.
