Appendix B Phone Tools
(GSM/GPRS)
B.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.
B.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.
B.1.2 Inserting a SIM Card
Note: If the battery is already installed, you must remove it before inserting the SIM
card.
To insert the SIM card into the PDT:
1. Remove the 4 screws from the GSM End Cap with a screw driver, Torx type and
size 8 (T8). And then remove the GSM End Cap.
