Before you start.

  1. Download, install & Run the Samsung & ZTE Client
  2. You will also need to enter your username and password and click “save login data”
  3. Make sure “main Server” is selected under the settings tab
  4. Make sure you click “Save Login Data”

please make sure if you copy and paste or enter User details manually that you do not inadvertently put a space at the beginning or the end of the user name or the password, this will cause the message “unable to get balance or counter zero”.
