em..however maxis provide the free calls and sms to supp line.. bt depends on wat type of plan tat u take it..
i would like to share my experiences at here..hmm..

i m using maxis supplementary plan (which RM10/ month) nw and i found it is more expensive than using hotlink active 10!!
(both are low cost and more suitable 4 student)
maxis Supplementary plan = RM 0.30/min + RM0.05/ msg..
hotlink (active 10) = RM 0.15/min + RM0.01/ msg..
seen i had change frm hotlink to maxis supp line..i found tat i have to pay 2X of my normal phone bill..wat my point is.. Supplementary Plan is cheap( RM 10/ month) but its is nt cheap 4 those who like to sms n phone calling..
so if u wana maintain ur phone bill less than < RM 50, better to get HOTLINK.....
cheers HOtlink
