5 Using the Phone Features

Use the HP iPAQ Mobile Messenger phone to make and receive telephone calls and send and receive Text and MMS (Multimedia Message Service) messages. Your mobile phone service provider may provide other useful services such as voicemail.

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/EDGE (General Packet Radio Service/Enhanced Data Rates for Global Evolution), or you can use GSM (Global System for Mobile Communications) for dial-up access.

For information on establishing GSM/GPRS/EDGE data connections, refer to Chapter 7, ”Making Data Connections.”

NOTE: EDGE is an enhancement to GPRS technology and enables higher speed data connections than GPRS. This means faster phone multimedia capabilities such as sending and receiving SMS/MMS messages, and sharing video clips. Check with your service provider to see if they support EDGE technology. If your service provider does not support the EDGE network, the HP iPAQ defaults to GPRS.

SIM Card

A Subscriber Identity Module (SIM) card is required to operate the phone features on your HP iPAQ. 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/MMS 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 HP iPAQ 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.

NOTE: tSee your local telephone directory for emergency numbers used in your area. Emergency numbers can be dialed without a SIM card being inserted in the HP iPAQ and there is no charge for emergency calls.
