If you have a Blackberry device that was not purchased from your own service provider, bought second hand or as a gift, then sometimes it may be necessary for you to amend the APN settings on your Blackberry.

Due to requirements CAMultimate and some other third party apps may require a direct TCP or HTTP connection to the internet, therefore this TCP setting needs to be corrected in order for the application to access the Internet and function successfully on your Blackberry.
