Hi MacForumers, I will be in the United States (and Canada for a short time) for about a month and am wanting to use my unlocked Australian iPhone. I am going to use the phone primarily for data - Google Maps, Safari, etc. (won't Google Transit directions by valuable?) but may make a few phone calls. I obviously don't have a social security number, US residency, etc. so signing a contract is out of the question. My first thought was AT&T - they've got the largest network and carry the iPhone in the States already. My understanding is AT&T just stopped offering an unlimited data plan for pre-paid customers. What a shame. Now they charge $5 for one MB or something. That'd obviously be a last resort. Is there any other AT&T package that I can go on that'll give me cheap/unlimited data that doesn't require me to sign a contract for 24 months/go about a credit check? After AT&T's denial, I've had a look at T-Mobile. They've suggested a FlexPay Plan, which is a month-to-month service and does not require a credit check or contract. $30 for the basic voice service + $25 for unlimited data. This is going to work with my unlocked iPhone, right? So for $55 I've got unlimited data on my iPhone for the month - 3G when in 3G coverage otherwise EDGE. I'll be able to hop of my flight from JFK International Airport and pick up a T-Mobile SIM and pop it in my iPhone? Does anyone have any other suggestions for pre-paid/no contract phone service that has a reasonable data scheme? T-Mobile is looking like the best option at the moment - hopefully the 3G coverage shouldn't be too much of an issue. Thanks in advance.
