SingTel Prepaid Card - Optional Free Incoming Calls

You can optionally, subscribe to a daily free incoming call (FIC) plan to talk all you want.

In a nutshell, how this will work for you. After getting the SIM card, you need to do the following
a. dial *130# on your mobile. This is a short code that activates your daily FIC plan.
b. expect to be charged a flat-rate of S$0.60 per day to enjoy the plan. This charge is taken off your main prepaid account balance - if you have just gotten the S$8 hi-card, you should have S$10 in the main account (I will get around to explaining the account balance part soon)
c. if you terminate the service, its going to cost you S$1.50 to stop it.
*rates may change so do check first.

So should you take advantage of the FIC plan?
Well, if you are expecting to receive at least 8 mins worth of voice calls per day based on current rates, you should have recovered your FIC plan. (if you forgotten the rates, go to my post on How much does it cost to buy a SingTel prepaid SIM card)
