Using Your SIM Card

bought your phone. You will not be able to make or receive
calls if you do not have a SIM card inserted in your phone.

The SIM card is a 'Smart Card' that contains your phone
number, service details and memory for storing Phone Book
numbers and messages. You can therefore use your SIM
card in someone else's GSM phone and you will be charged

secure. Do not bend or scratch your card and avoid
exposure to static electricity or water.
