 
16 Instant messaging (IM)
Take text messaging to the next level by experiencing 
instant messaging in a wireless environment. Engage 
in instant messaging (IM) with friends and family, 
as long as you all use the same IM service. Check 
with your wireless service provider for availability. 
Before you can start using IM on your phone, you 
must first subscribe to your wireless service 
provider’s text messaging service. While only SMS 
capability is required to use the service, GPRS 
improves the speed of instant messaging. You must also register with the IM 
service you want to use. See “Register with an IM service” on page 90 for more 
information.
Note: Due to variations in IM and wireless service providers, you may not 
have access to all of the features described in this guide.
• IM SERVICE PROVIDER ICONS
Since each IM service has its own display text and icons associated with it, the 
display text and icons on your phone may appear differently for each IM service 
provider. If you have any questions about the differences in the various IM service 
providers’ display text and icons, contact your wireless service provider for more 
information. The following table shows examples of IM icons and their descriptions:
