  • Once you have successfully applied IDD001 Service, you can make IDD calls while you are roaming abroad.
  • IDD call charges will apply once a call is answered (even if the call is answered by any automatic answering systems including announcement, tone machine, etc). In some circumstances, IDD call charges may still apply to the ringing time due to special call routing design of third party service providers in the event if a call is not answered.

If you have any query on the above information, please contact our Customer Care department.
