ok other than contacts and other stuff, what is your micro-sim card for? just wondering!
Basically your phone number is tied to the SIM card. the phone reads the information on the sim card and connects to the network. if you move a SIM card to another phone, the phone number moves too. in addition to that, it also can store some contacts.
In the case of an iPhone, no Contact data is stored on the Micro-SIM. No pictures or ring tones.
The iPhone supports the ability to import date from an existing Micro-SIM but the Apple provide tools do not support writing Contact data or other data to the Micro-SIM.
As an earlier poster indicated, only your individual SIM data is on the Micro-SIM. This data is used to authorize your device to the carrier's network.
