iPh1 four w/ T-Mobile sim in AT&T service area
I just activated my factory unlocked iPhone 4 with a ST T-Mobile sim. Voice and SMS works perfectly, but I'm on vacation in Montant, which does not have T-Mobile service. The phone is defaulting to AT&T service.
I've tried various APN settings with both both unlockit.co.nz and the Straight Talk iapnupdate.straighttalk.com / iapnupdatetfdata.straighttalk.com without any success.
Should I be able to use data on the A&TT network with my setup? I haven't used my phone on the T-Mobile network yet since I received the sim.
