Why a call to the USA 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 & Conditionscsl adds local airtime to every IDD call
csl IDD 001 calls also count local call minutes or incur local airtime charges.

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.
3 Hong Kong, IDD 1968 Terms & Conditionscsl prepaid limits internet calls after the fair-use limit
