Yoodo is one alternative.
Just subscribe to Rm 3 for 50sms, repeat every 50 days before the 60 days termination.
assuming you do that for a year = 30 days + 50 days / 365 days = 4.5 times = Rm 13.50 total cost.

You can also opt for the Rm 5 for 100 mins.
Another one which azhar75 hinted is Hotlink Pantas.
