The iphone must be unlocked, then you can use the phone on t mobile.
Search how to unlock the iphone. You could break the phone if not done correctly,
so I am not telling you too do it, just letting you know there is a way.
no, you dont. you can jailbreak your iphone and run it on tmobile's network, if you have a tmobile sim card. but on tmobile, you cant have 3g speeds, only 2g.
Of course, the iPhone 3G and/or the original iPhone will take any normal sim card; the 3G iPhone will take the 3G sim as well.
To unlock your iPhone with you Tmobile SIM card I would suggest you goto easyiphoneunlocker.com they have a very easy to use tool to unlock and jailbreak your iphone. I was able to unlock my iPhone 4S within in 10 minutes with no issues.
no unless it is unlocked... .
Yes. AT&T is a GSM carrier, meaning all the phones are GSM phones, meaning all the phones require a SIM card to work on a GSM network.
Yes, but the iPhone 3GS will probably only work on the slow EDGE network because it lack's the proper antennas to use T-Mobile's strange bands of 3G and 4G.
Yes you can. You can put any tmobile sim card into any tmobile or unlocked phone and it will work perfectly. Although you may need to add some features to your plan :)
yes a plateau sim card will work on the iphone all you have to do is go to plateau and have them unlock it.
Sadly, no you can't. This is because Verizon Does not run on sim Cards. I sure wish they did, because I'd get an iPhone.
Can you use a verizon iphone with tmobile account
If you have used TMobile in the past, you can unlock your HTC Touch Pro2 by calling Tmobile. Alternatively, you can purchase unlocking software on websites such as eBay which will allow the unlocked phone to work with an AT&T sim card.
Yes if you buy an iphone and use geohot's black snow and get an international sprint sim
