Connectivity
Your device offers several options to connect to the
internet or to another compatible device or PC.
Data connections and access
points
Your device supports packet data connections
(network service), such as GPRS in the GSM network.
When you use your device in GSM and UMTS networks,
multiple data connections can be active at the same
time, and access points can share a data connection. In
the UMTS network, data connections remain active
during voice calls.
You can also use a Wi-Fi/WLAN data connection. Only
one connection in one wireless LAN can be active at a
time, but several applications can use the same
internet access point.
To establish a data connection, an access point is
required. You can define different kinds of access
points, such as the following:
● MMS access point to send and receive multimedia
messages
● Internet access point (IAP) to send and receive e-
mail and connect to the internet
Check the type of access point you need with your
service provider for the service you want to access. For
availability and subscription to packet data connection
services, contact your service provider.
