Sadly, Telstra mobile customers can no longer use their mobile phones to make free international calls through our service. An agreement between Telstra and our network service provider terminated on 1 February 2011. Accordingly, we now cannot provide our service to Telstra mobile phones and any other mobile phone companies using the Telstra network. We hope that a new agreement can be negotiated, but do not expect that to happen any soon. If you are a Telstra customer, you may consider changing your service provider to 3 or Vodafone to continue using this service.
