Activate att sim with existing phone

[Zaveri]

Hi,

I have an AT&t sim card with motorola phone but now i also have an apple iphone, but i have doubt about apple iphone's compatibility with AT&T sim card. Is there any one who knows how can I use my current AT&T Sim Card with a brand new iphone ? I am an old account holder, right now i have 70 dollar a month contract from AT&T.

Thank you

The iPhone uses the EDGE network and is not yet compatible with AT&T. and even if you unlock Jailbreaking the iPhone this will void the warranty of an iphone and Apple will not replace the device if something should goes wrong with your iphone.

why dont you buy Apple iPhone 3G It will cost you 99$, its a Revolutionary 3G mobile phone, you can activate your current sim card on Apple iPhone 3G and download Thousands of applications at the App Store. But if you have prepaid sim card then it may be difficult to use iphone with prepaid sim card.

See if you are planning to buy an old iphone then your sim will not gonna work wioth an old iphone, buy iPhone 3G. While also being locked to AT&T, the iPhone 3G works with any AT&T SIM once activated. You can then change your plan also and enjoy AT&T service with Apple iphone.
