My calls keep dropping due to

Lately (as in everyday for the passed two weeks), my calls have been dropping and the message that pops up is "call failure". I always thought that it was bad reception as my boyfriend has quite poor reception in his area. I recently noticed though that the calls are only failing once I've hit the 2 hour mark of talking. I am in a long distance relationship so I'm calling from NZ to Aus if that has anything to do with it. It only started happening once I switched carriers when I got back to NZ 2 weeks ago. Is this happening to anyone else? How can it be fixed?

Re: My calls keep dropping due to

Are you using the cellular network for the call? Or FaceTime?? Some other VoIP app like Skype? If using cellular... it's a network limitation imposed by your provider... you can try alternatives - FaceTime, Skype, etc...
