Getting Started
Inserting the SIM card and battery
When you register with a service provider, you receive a SIM card 
(Subscriber Identity Module card). Your phone must have a SIM card in 
order to make calls. The SIM card is a computer chip that contains your 
phone number, phonebook information, and service provider information. 
Handle it with care and do not bend it or expose it to static electricity or dirt. 
Be sure the power to your phone is off before you insert your SIM card.
1. Press the notch on the back 
cover and slide to remove.
2. Remove the battery. The battery 
has side tabs to make it easier to 
grasp and remove.
