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.
