If Ambassador infinite launched, i will assume it is RM30 cheaper like RM120.
My major concern is the "game rule", only allow 5 devices connect tethering at same time.
Come on, i has more then five devices in house, TV, TV box, phone, game phone, tablet, computer, IP camera, smart home device. Not yet add my wife and kids.

Only advantage on infinite plan for me is, i can watch live TV programs without quota concern. But live TV is boring and a lot ads.

So far, i am using three IP camera. Not much data consume because i only check when needed. Configured camera send video to cloud when alarm triggered.
If you want to watch your camera for long period, then you has to measure each camera consume how many data per hour.
