Which US sim card will give 3G on UK iPhone 3GS

[Droooooj]

Which US phone network's sim card will give me 3G on my UK iPhone 3GS? I'm travelling to Florida.

I read that t-mobile and at&t use different 3G bands or something, so if incompatible you might end up with Edge?

My mate I'm travelling with has got an Australian 3GS iPhone, and has the same question for his.

Both our phones are unlocked.

AT&T is the SIM card you want. It'll give you 3G speeds.

AT&T or any of its resellers like straighttalk, redpocket, h2o.

Straight Talk from Wal-Mart would be the best choice, $45 a month (if you plan to stay in the US for quite some time). Has 3G for iPhone.

Other than that, AT&T.

Not staying long Dontwalkhand, just 2 weeks, but wanna have access to maps, gps, email and stuff without lugging my laptop round.

I'm really just looking for a Pre-paid/Pay As You Go sim with no contract and about 250-500mb per month data usage.

Is there at&t shops where i can go and buy a sim from when i land?

Plenty of AT&T stores around ..Though with prepaid, you may have to cut your SIM though, which isn't hard at all (if an iPhone 4/4S)

You might have a hard time getting smartphone data with prepaid AT&T plans.
Access the Web, email, social networks, and more! Add to your GoPhone 10¢/Minute Plan, $25 Monthly Plan, or $2/Daily Unlimited Plan. Smartphone users must purchase a data package with any plan to use data services on their device.
$5 for 10 MB
$15 for 100 MB
$25 for 500 MB

I think the straight talk plan gives you 2GB of data for $45 along with unlimited talk and text in the US so that might be a better plan. Up to you.

Hmm.. I'm getting a little confused...

To use StraightTalk, Redpocket, h2o, etc... do I need to have an AT&T sim card first?

Or do these guys simply use AT&T's network coverage? (eg in the UK VirginMobile uses T-mobile's network)

 

[Applejuiced]

They just use AT&T's network.
You just go straight to them, no need to contact AT&T. They are separate companies.

A pre-paid SIM card activates your GSM mobile, without you having to enter into any contract with the service provider. It already has airtime c SIM Card for USAredit included in it, when you purchase such a card. I'm using holiday phone sim for my international travel.
