My iphone didnot recognize contacts from my sim. Anyone knows how to proceed ?

It is widely known that the iphone does not use the sim for storage at all and also you can not read your sim contacts on the iphone.

the easiest way is to use your old phone:

1) sync old phone to your computer
2) save contacts to your computer (in Windows - save to Windows Address Book)
3) sync saved contacts to your iPhone via iTunes

I've done it with a TMobile MDA

so it simply depends on your old phone or borrowing one that is able to connect to your computer

Problem solved. Tahnk you.
