Inserting the SIM card
The SIM card is a small rectangular plastic piece that contains your phone number and account
information. It is included with your wireless service provider’s documentation and is often
referred to as a “smartcard.” If a SIM card did not come with your communicator, your wireless
service provider will provide you with one when you subscribe to their service.
You must insert your SIM card into your communicator before you can use it for wireless
communications. Since calls are billed to your phone number, you can, however, move your SIM
card to any phone that uses a SIM card, and the calls will be billed to your account.
To insert the SIM card:
1. Remove the SIM door.
2. With the contacts face-up, align the notch on the SIM card with the notch on the door and
insert the SIM card into the slot on the door.
3. Replace the SIM door.
