Barred International Locations
Because of an increase in the number of unauthorised call activity and modem-jacking incidents Optus has barred all direct dial calls to the following destinations:
-
Diego Garcia
-
Sao Tome & Principe
-
Guinea-Bissau
If you need to make a call to any of these destinations, contact Optus Customer Service on 133 937, as access to a specific number may be able to be restored.
Alternatively, connections can be made through Operator Services by dialing 1225 (charges apply).
