Unlocked iPhone query

[txlisa]

we will be moving to thailand next fall and would like to know if an unlocked iPhone can be used there with any carriers

[djaidee]

I would say yes, but if not you have to buy another one in Thailand.

Yes so long as you order the smaller Sim card used for apple iPhones.

Yes, when you get to Thailand you go to dtac store for example and purchase sim with data plan - so you can have calls and internet on your iphone. There are usually several to choose from. Just ask the staff at the store.
I unlocked my 3G iphone last year from USA and just purchase sim with data plan. I got the 1 year plan so I can keep the same phone #, just have to re-charge and renew for more months before my 1 yr. is up.
Just in case your phone is not unlocked, you can get it unlocked for reasonable price in Thailand.

Make sure when you unlock that you understand the consequences. Some phones with the newest baseband can only be unlocked by upgrading the baseband to an iPad which causes you to lose GPS functionality.
