Hi nikki_5543, for high rise building, there are 2 side of infra involve.
1. Service provider will provide infra up until Comm Room (ground floor)
2. Developer/Building Mgt are responsible for infra from Comm Room to each property unit.

Most of building pre 2014 (just a guess) are equip with VDSL. I believe your building were built with VDSL and TM (at that time support VDSL) provision broadband service to your building.

Then, 2016-2017, TIME together with Building Management, lay full fiber solution (probably with massive discount) and provision their broadband service.

So, what you can do? There is 2 solutions,
1. Terminate Unifi and subscribe to TIME.
2. Get most of the tenant to demand a fiber infra replacing VDSL from the Building Management. Then only then, can TM provide service higher than 30Mbps to your building.

For mine, the installer called in the morning of the day.

Call 100 and check with your order number.

Mine is suppose to be on Sunday, but there's no follow up nothing. Until I called them just now and they told me my order was cancelled for no reason.

I am awaiting my call back before 10pm later.

Very nice!
