I do not currently have a contract/account with AT&T but I have bought a factory unlocked (I often travel to the UK) 3G S from Italy. I have heard that AT&T now have month-to-month contracts if you do not get a phone with them (the 2yr contract is to pay off the heavily subsidised mobile I believe) so I went ahead and bought a AT&T SIM card on Ebay. My question is how do I get the month-to-month deal. Do I just activate the SIM on AT&T's website and go on from there or do I need to call them? I'd rather not have to go to an AT&T store.
