    AT&T iPhone will roam on other countries, you have to call AT&T and activate the roaming service. Data plans are not unlimited and very expensive, avoid using cell data out of the country, use only Wi-Fi. Roaming charges are also expensive on top of the regular monthly service fees.
    There are factory unlocked iPhones, they cost around $700.
    TurboSIM and other things like that might work, but you have to be confident on what exactly are you buying.

    At the iPhone hacks section.
    Are you asking about if it will work with other carriers sims as factory unlocked or if your AT&T sim inside the iphone will work in other GSM networks?
    If you purchase an i4 for full price from Apple it will come factory unlocked.
    If you get it from AT&T or any other seller with an AT&T account it will be locked.

    Thank you Guys for your answer. and yes i'm asking about if it will work on other carriers so if it's from AT&T it will be locked, even if i unlocked the iphone and lost apple support?

    Provide better details!

    What type of phone
    Firmware version
    What baseband
    How long are you going to be out of country?
    What do you mean locked even if it's unlocked.
    What do you mean lost apple support shouldn't have anything to with unlocking.

    I've taken my usa 3gs ultrasn0w unlocked iphone to the middle east and it worked just fine on orange and would have roamed on 5 other networks as well.

    If your bought your iPhone through AT&T, it is locked to them. To use it in another country, you have two choices:

    1. Buy an international plan and pay exorbitant charges.

    2. Use a piece of hardware called the Gevey Turbo SIM to unlock your iPhone so that you can use it on a local carrier when you travel internationally.

    If you have any questions about Gevey, Google is a really good resource and I'm not being snobby or anything!

    Depending on WHEN it was purchased it MAY still be unlockable. Check your modem firmware. Never assume anything.

    We still do not have any specs on this phone...

    IS the iPhone not available in your country? Or is it more expensive?

    It looks like the gevey SIM is your best option. http://applenberry.com/store/gevey-sim/gevey-ultra.html
