or HSPA is available, the HP iPAQ uses the technology and reverts back to GSM/GPRS/EDGE if
WCDMA or HSPA is unavailable. Your HP iPAQ also supports WCDMA/HSPA in three different
frequency bands (900/1900/2100).
GPRS/EDGE
The GPRS/EDGE technology enables the mobile phone network to be used for messaging or to access
the corporate network or the World Wide Web.
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.
Differences between GSM and GPRS/EDGE/WCDMA/HSPA technology
GSM technology is typically used for voice calls and text messaging, whereas GPRS/EDGE/WCDMA/
HSPA technology provides a data connection to the Mobile Phone Network that can be used for Web
browsing, Multimedia Messaging Service (MMS), or accessing your corporate network.
NOTE: If data services are used, they are charged additionally to your standard mobile phone service.
Check with your service provider for data services and cost.
If you have trouble with your connection, contact your service provider.
