1300 is considered special number
My current plan includes bundled minutes, but cannot be used for 1300 and 1800, charge 30 sen per minute

But from mobile phone both are special numbers charged at a higher rate

You are right. Toll free and local call charge if you call using TM line. Using cellphone? Forget it. That is why I still have regular phone ... but how many time I call these number? 

Depends on telcos. Mine normal numbers have bundle, I never finish them so I never get charged for normal calls
Special calls to 1300 and 1800 depends on telcos, mine 30 sen per minute

Copy Paste from TM

Each local call is charged at 8 sen for the first 2 minutes or part thereof and 4 sen for each subsequent minute or part thereof. Example: Local call being made for 3.5 minutes - total charges : 8 + 4 + 4 = 16 sen.

I use Unifi and add RM20 extra for unlimited call throughout TM network. It also comes with 600min worth free call (I think this include international call as well)

Using cellphone, the rate depends on the company or organization you call. There is no fixed rate I believe.

Not sure if this 1 300 charge still valid but this is how it was in 2013    See the difference in charge. The problem is they never said how much it will cost you
