Depends on your area, but generally they only offer to those with strong coverage i.e. around 20Mbps. By end of November, the website said will open the application to all within the coverage area.

They also called and offered 30-days trial ... (actually it's agreed 24-months contract, with 30-days cooling off period) ... so, if not satisfactory, can cancel and return the B618 modem (with simcard) to nearest Kedai Telekom.
So far so good ... only cons is my area seems to have very low upload speed ... supposed to be 20Mbps download/upload ...

Currently testing the 'unlimited' quota ... passed the 1,000GB mark already, will see when will the speed be throttled, if follow those 'fair usage' policy for wireless broadband network plans ...
