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 wireless LAN data connection. See
‘Wireless LAN’, p. 70. 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:
•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.
