I do not know the answer to your earlier question but you mentioned earlier in post #14 about fibre cables behind lamp posts, that's where I got the idea it was on lamp poles, maybe I misunderstood.

Actually you can try to get a better answer from a TM technician assigned to your areas telephone exchange.

But the chance of your area getting Unifi covered is high since you say your housing area some parts already got Unifi. TM will eventually cover the blind spots if the exchange covering your area is already serving Unifi.

What I was trying to say earlier is those exchanges earlier not serving Unifi service, chances of getting it will be slim for expansion.
