Carrier iPhone 4 ATT Unlocked in EUROPE used with prepaid SIM cards

[PracticalMac]

Hello all,

I want to give my UN-locked ATT (by ATT) iPhone 4 (not 4S) to my relatives who live in Europe (Austria and/or Czech republic)

Focusing at NON data plan, prepaid SIM card setup, data plan is not required but nice.

Can it be done, and what are the options/companies to use?
Links to companies please.


Offhand, I believe the iPhone 4 is fully compatible with T-mobile in Europe (closer to ATT network).

Thanks

No one try this?

If the phone is unlocked as you say it is then it will work without a problem. All carriers in Europe use GSM and the iphone 4 will support GSM. You might want to confirm the phone is unlocked before you ship it over by putting a US T-Mobile Sim card in it and see if it works.

Yes, it should work fine. You just need to be sure that the network matches the specs of the iPhone 4. I used an unlocked 4s (same bands as a 4) in Spain with a pre-paid SIM and it worked great.

2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100

It was on T-mo at one time, so yes.

4S is somewhat different, but close enough.
But this is what I wanted to confirm, thank you!

Czech did not have any coverage for frequencies the iP4 uses.
