Today, I went to IT Hypermarket at Cineleisure, Mutiara Damansara to register for P1 Wimax. Actually, I have been thinking to move from Celcom Broadband to P1 Wimax since two months ago. You can refer to my entry here.
What you need to prepare is just bring your MyKad and also driving license for registration. The registration fee is only RM100. After you have paid the registration fee, you will get the P1 Wimax modem and can start using P1 Wimax after one hour later.
