Thanks for information.
I went there to apply permit for my nvidia shield tablet and it is quite easy.

FYI any personal use telecommunication devices (which got wireless) requires SIRIM AP.

the payment is

1 - 3 units: RM 100
4 - 6 units: RM 200
7 - 9 units: RM 300
10 - 12 units : RM400

However, this payment is subjected as per item + per name+ per year.
example:
if i have 2 unit shield tablet payment is 100
if i have 4 unit shield tablet the payment is 200
if i have 1 unit shield tablet and one unit xperia Z3, the payment will be 200
if i have 2 unit xperia, and registed 1 unit xperia under my name and and another under my friends name, the payment is 200.

if let say i import 1 unit within july for example, i required to pay 100. if i were to import another 1 unit within august, i still required to pay 100.

the maximum one person can register within one year is 12 units.

Hope above helps.

I still required to pay for the AP even though my device only has wifi (no other GSM feature).
