for those who monthly calls are RM140 and above, suggested to sign the p148 plan from Celcom. It comes with 5GB data plan free of charge (additional usage will not be charged, just throttled instead). Calls are 10 cents per minute only, regardless to which telco.

The things is, this is a corporate plan, meaning you need to state your company. But, you just have to show them a name card. Thats all.
