Starhub Green Prepaid Card - Optional Free Incoming Calls

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

In a nutshell, how this will work for you. After getting the SIM card, you need to do the following
a. dial *133*1# on your mobile. This is a short code that activates your daily FIC plan.
b. expect to be charged a flat-rate of S$0.59 per day to enjoy the plan. This charge is taken off your main prepaid account balance
c. if you terminate the service, just dial *133*0#.
*rates may change so do check first.
#a minimum balance of S$1 must be kept in the main account else your FIC plan does not work

So should you take advantage of the FIC plan?
Well, if you are expecting to receive at least 6 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 Starhub Green Prepaid Card)
