lol.... looks more like a low move from Singtel to seize this opportunity for free ads... I please you lor.... those Heya, Simba, etc.... like less than $10 a month and plus those rollover unused data and roaming data, etc.... it's already like unlimited liao no matter how they use their phone..... to put it in perspective, it's like getting the bagalas to hold your big sim card for advertisment and pay them $120 over a period of 12 months.
