6.1 Using the Phone Features
Use the PDT to make and receive telephone calls and send and receive SMS (Short
Message Service) messages.
Your mobile phone service provider may provide other useful services such as voice mail.
The phone can also be used to connect to an Internet Service Provider (ISP) or work network
so you can browse the Web and read e-mail. You can connect to the Internet or work
network over GPRS (General Packet Radio Service), or you can use GSM (Global System
for Mobile Communications) for dial-up access.
6.1.1 SIM Card
A SIM (Subscriber Identity Module) card is required to operate the phone features on your
PDT. The SIM card is a plastic card embedded with a computer chip that stores and
transacts data. After the SIM card is activated by your mobile phone service provider, the
computer chip will contain information about your phone number, service, registration
information, and contacts, as well as memory to store speed dial numbers and text or SMS
messages that you receive.
With the exception of emergency calls, the SIM card must be inserted into the SIM slot under
the battery on the back of the PDT in order for voice/data calls to work.
To dial an emergency number, from the Phone keypad, tap the emergency number
appropriate for your region, and then tap Talk or Send.
Note: See your local telephone directory for emergency numbers used in your area.
