Error message: "java.io.IOExeption: could not open tunnel - failed"

This error message can appear when you try to connect using the TCP/IP connection method.

For TCP/IP,  Mobile Admin requires that you use an Internet access point name (APN) instead of a wireless access point (WAP). Contact your carrier and find out what settings you need to configure to use their APN.

A list of known Internet APN settings can be found here:

On a BlackBerry smartphone, you can typically enter or modify Internet APN settings in the following location:

1. On the main screen of your BlacBerry smartphone select Options
2. Select Advanced Options
3. Select TCP

This location can vary a bit with the Theme on the BlackBerry though.
