Using the correct GSM Profile
Communication Manager comes pre-configured with several profiles that
should be used depending on how your device was provisioned. Each
profile defines different connection methods to the network based on the
Access Point Name (APN) your SIM has been provisioned to use.
The APN specifies the external networks that a mobile device can access. It
also defines the type of IP address to be utilized, security mechanisms to
invoke, available value added services, redundancy, and fixed end
connections.
Each pre-defined profile in Communication Manager is designed to
connect using an APN to the Cingular network. A brief summary of the
APN profiles is listed below. Depending on the service to which you have
subscribed, you will have one of the following groups of profiles available
to you:
Group 1
• EDGE/GPRS Accelerated
: This is the standard profile for users with
profile group 1. In most cases, it will provide the best experience. This
profile can be used to connect to EDGE, GPRS and UMTS networks.
Additionally, data acceleration will be inherent in some connections
established with this profile. Data acceleration can be configured on the
Acceleration tab of the Settings window.
• EDGE/GPRS Non-Accelerated
: This is similar to the accelerated profile.
However, data acceleration will not be used.
Group 2
• GSM Connect — Proxy
: This is the default APN/profile provisioned for
most users with profile group 2. Proxy APN provides a Cingular
private IP address and does not allow unrequested data to pass from
the Internet to the mobile user.
• GSM Connect — Public:
Provides a public IP address and does not
allow unrequested data to pass from the Internet to the mobile
user. Additional charges may apply.
