Will a T-Mobile SIM card work in my iPhone? They are both GSM/EDGE.

Will a T-Mobile SIM card work in my iPhone? They are both GSM/EDGE.

Out of the box, the GSM version of the Apple iPhone (up to the iPhone 4) and the iPhone 4S will only work on Apple approved GSM providers (i.e. AT&T).

T-Mobile SIM cards can be used in an iPhone that has been jailbroken and unlocked via third party software. There are a variety of commercial and non-commercial software options available which unlock the iPhone.

Though unlocking has become very common for users that do not want to be tied to a particular carrier or bound by a contract, users should understand that unlocking is performed 'at your own risk'.

I got an iphone 4 IOS4.1 with T-mobile. It is not jet unlocked. My question is, will it work if I cut my old T-mobile Sim Card into a Mini Sim Card and insert it into my iphone? Thanks

I'm getting a IPhone 3 from a friend that has been jailbroken and use it with my T-Mobile SIM card. And yes, it DOES work, my sister just did that 2 weeks ago. :) My question is: will my data plan change/increase because of the changes? I currently have an ANDROID. Thanks in advance!

I just got an iphone 4 and it is unlocked but the sim card is way smaller the sim card of tmobile and i tried cutting it but it didnt work any idea?

Your iPhone must be unlocked first...
You must use a NON 4G T mobile sim card
You can either have a "professional " cut the t mobile sim card down to fit in your iPhone ,OR you can purchase a sim card cutter on eBay for about $5 (that is wht the professional guy uses anyway)
Than after installation ,the phone must be programmed to work with the new t mobile card
(a Craigslist professional can do all this for you for about $40)

Good luck to you!
