Getting Connected With WAP
The most common issue with WAP connections is missing Access Point Node (APN) settings on the device. The APN settings are unique to each service provider. An informal list of known good settings, as reported by our customers, is below. You should however, contact customer support for your provider to make sure you have the correct settings.
To set the APN settings, go to Options->TCP on your Blackberry. Enter the APN, username, and password. Not all service providers require a username and password.
The second most common issue is the Blackberry built in firewall blocking the connection. To reset the firewall, go to Options->Firewall on your Blackberry. Choose “Reset” from the track wheel menu. This will cause the Blackberry to prompt for permission during the first connection attempt made by any third party application. Be sure to choose “Allow” from the firewall popup when it is shown.
Informal APN settings by service provider. Note this is an informal list, no guarantee is made. You should contact your service provider’s customer service for verification of proper settings:
