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.
