  • Turn your phone off then on.
  • Check balance - you need credit on your account to make a phone call. Simply visit your online account or dial *108#.
  • Are you dialing the correct number? Please remember to dial numbers in international format.
  • Do you have network coverage? Like any other mobile phone service, you need to have network coverage of more than one or two bars (as displayed on the handset screen). Often switching your phone off and on will repair any temporary network issues.

If you have followed the steps above and it still hasn't solved your issue please contact us.
Why is my balance reducing when I am not making any calls or sending text messages?
Ensure that you switch data roaming OFF when you are not using it, as you will still get charged for data every time you use a data service such as incoming emails or notifications.

You may also be incurring charges related to iMessages and/or FaceTime. You should switch both of these services OFF in your iPhone settings.
