I did mentioned Tunetalk in point -3 on choosing what you like above ...

Yes, TuneTalk does have interesting plans. The Data plans are enticing. I calculated the RM2 weekly plan as a very cost effective option for the moderate whatsapp/wechat users (hint: topup of rm50 + rm100 and figure out how it can make your whatsapp comfy for the next 1.5 year). Yet, the bottomline still depends on one's requirement.
