Connectivity
Your device offers several options to connect to the
internet or to another compatible device or PC. For more
information on other connectivity methods, see the
extended user guide on the product support pages of the
Nokia website.
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
