Will my Uk bought iPhone 4 work in USA with a USA micro sim

I have an apple bought iPhone 4 which is unlocked from the uk and I'm off to USA for a few weeks soon and need to know if my phone will work out there and if I can buy a USA micro sim and use that in my phone too.

iPhone 4, iOS 4.3.3

Hi woody. If it is unlocked you can use US carriers on your phone. What is your carrier in UK? I think you can use it inside USA aswell. Some US carrier offers Micro sim, but i don´t think that there are any prepaid micro sim card´s.

Remember also, that some carriers use different technology, like CDMA (Verizon) so you can´t use those carriers on your phone.

If it's factory unlocked you will be able to use either AT&T or T-Mobile in the US with a few caveats.


1) AT&T does NOT offer a prepaid plan for the iPhone. It is post-paid only.


2) You can get pre-paid service from T-Mobile, however, Visual Voice Mail, MMS messaging, 3G data and FaceTime will NOT work on the US T-Mobile network. If you can live with the lower data speeds for a few weeks and primarily want it for voice calls and/or will be using WiFi for most of your data, T-Mobile is probably the better bet IF they provide coverage in the area(s) you'll be visiting.

In the UK I'm on O2 but the phone is an apple bought factory unlocked phone. I have seen that you can buy at&t micro sims or data sims which you can use while out there with no contract and you just pay for data allowance.


I was just not sure if my phone would actually work there and take the USA sims. I had heard about the verizon phones and thought mine wouldn't work there.
