International Calls (IDD)

We have tied up with ZONE Telecom Pte Ltd for international calls.
You can call IDD by dialling 1511 + country code + area code + All charges will be billed to you by Zero1. For now, you cannot make direct international calls and SMS simply by adding a 'a' sign in front of a number - this function will be only available later.
You can view our rates below.
