This really coming, when is needed most, most of us
Finally Apple announced their new iPad Mini 3 and iPad Air 2 at a press event yesterday, but actually something nice was also announced which went unnoticed, known as Apple SIM.
The Apple SIM will be pre-installed on iPad Air 2 WiFi with Cellular version and it will apparently let you choose between different mobile carriers for your iPad
When the iPad Air 2 launches, the Apple SIM will be available in the U.S. and the UK, and three carriers in the UK will support it, AT&T, Sprint and T-Mobile, and in the UK it will be supported by EE, Apple explains below how the SIM card works.
So basically you should be able to easily switch between carriers ranging from AT&T, Sprint and T-Mobile on your iPad Air 2 without any long contracts. If Apple decides to bring this new Apple SIM to the iPhone in the future that could mean some major changes to the way mobile carriers offer their services.
