Use caution when inserting or removing the SIM, and keep all SIM cards out of reach of
children.
1. Remove the back cover and battery.
2. With the gold contacts facing down, slide the SIM card completely into the
socket with the notched end oriented as shown.

Note: The angled corner of the SIM should be inserted as shown in the diagram on the phone. The
correct SIM orientation is necessary for your phone to recognize the SIM.
