Why a call to the UK 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.
