How to use Unicom mobile phone to call and send text messages to Sydney? ad hoc fashion

You must dial the international long distance area code.

Sydney's fixed telephone number 006 12 is followed by an eight-digit telephone number.

Eight digits after dialing 006 14 for Australian mobile phones (regardless of region).

For example:

Is the number your friend gave you a mobile phone number? Usually, the mobile phone number is ten digits of 0430 123456. When dialing, just dial 006 1 4 30 123456 and send it to the above number by SMS.

Unicom's Ruyitong can dial any messy card directly, but it's very expensive, about ten yuan a minute, I guess. For details, please consult Unicom customer service.
