An outgoing call on your Singapore cellphone cost around S$0.15-0.25/min depending on the type of plan you have.  Remember, when a mobile operator says they have FREE IDD calls to several destinations, it is NOT FREE as you still chalk up your outgoing airtime.  Our Global Callback converts these into FREE Incoming Calls whereby the telcos will NOT be billing you.  This is because we provide a gateway number to dial into and your call will cut after 1-2 rings and in 5-10 seconds, our servers will call you back. The system therefore works on the premise that you have free incoming calls on your mobile plan.  

Please note that our network also permits you to make LOCAL outgoing mobile calls to another local mobile or landline at only US$0.03 per minute which means you can make 5 times as many outgoing mobile calls!!   To sign-up just select our Singapore Callback service plan.
