Why a call to China fails

3 needs IDD and Roaming Service for 001 calls

A 3 line without the IDD & Roaming Service subscription cannot use IDD 001. Switch the service on with 3 before you call abroad.

3 Hong Kong, IDD 001 Terms & Conditions

csl adds local airtime to every IDD call

csl IDD 001 calls also count local call minutes or incur local airtime charges.

csl, IDD 001 Voice Call Coverage and Charges

3 treats a call back from call history as IDD 001

Dial through 1968 to use 3 IDD 1968 Service. A call to an overseas number from the call history menu uses the IDD 001 tariff instead.
