About Instant messaging
Instant messaging (IM) (network service) allows you to
converse with other people using instant messages
and join discussion forums (IM groups) with specific
topics. Various service providers maintain compatible
IM servers that you can log in to after you register to
an IM service. Service providers may differ in their
support of features.
Before you can use Instant messaging, you must save
the settings to access the service that you want to use.
The settings may be preconfigured in your device, or
you may receive the settings as a configuration
message from the service provider that offers the IM
service. You can also enter the settings manually.
