I'm new to prepaid so sorry if this is a stupid question.

Say if I choose the monthly 6GB that doesn't come with unlimited phone call, for RM35.

How are my phone calls being charged? Is it deducted from the 6GB too? But when you make phone call, you don't use data right? So how do they calculate it? Same goes for SMS too.

They charged by per minutes of each telephone call u made, deduct from your balance. Same goes to SMS

The "balance" refers to the 6GB right? Say I made a call worth RM1, they will somehow perform some conversion and deduct it in terms of bit/byte?

Charge from your credit balance, meaning if you reload RM40, then buy the RM35 data plan, you will still have RM5 balance.

If you make calls and SMS, your RM5 balance will be deducted. If no credit left cannot make calls.

Example if you reload rm40

Once u subscribe to the 6gb for rm35 will be deducted. Your balance will be rm5

Your call and SMS will be deducted from the balance of rm5
