SIM cards are inserted underneath the battery in the Blackberry Curve 8310.
The Research in Motion (RIM) Blackberry Curve 8310 uses a 3G Subscriber Identity Module (SIM) card for the simultaneous transmission of voice and high-speed data services. In addition to letting you make and receive calls, the SIM card also provides faster Internet browsing, global roaming capabilities when traveling overseas, GPS navigation, and the ability to store or transfer contact information. A 3G SIM card can be inserted into the Blackberry 8310 curve in minutes.
