How to avoid 1 minute calls?
When you dial a number you will hear a Beep sound after the call has been established or appears to have been established. The beep sound indicates that the billing has started. However if you cannot talk then hang up within 10 seconds of hearing the beep sound to avoid being charged for 1 minute call. Simply press *0 (star then zero) to redial the number within 10 seconds following the beep. Not only this will avoid 1 minute call being logged but at the same time your intended number will be redialed automatically.
