is unifi air similiar to unifi lite?

I just asked tm staff at tmpoint.

This is what I was told:
Unifi AIR cannot be applied, TM will contact you and ask if you want to try it, it will be one month trial, after that if you want to subsribe it will be 2 years contract. Labuan already has 2 people using this unifi air (as in their live stream of streamyx users offered unifi air as pilot programme)

unifi air uses tm’s own 4g/lte, small coverage. If no coverage it will use celcom 3G (celcom didn’t give them 4G to use)

kinda stupid, since most places that doesn’t have unifi fibre also most likely no unifi air 4G coverage.
