There's *always* going to be a not spot. And inevitably those dwelling in one will raise coverage issues, which is sort of obvious.
However if this were common across the country, the operator would suffer, so it is very likely the economics of your area don't add up if *none* of the operators offer service.
So without understanding the numbers involved in getting coverage at your favourite spot N, it's hard to say that it can be cost effectively solved by yesterday's technology, if at all..
For eg if a NIMBY meant that it would cost £1 million per user to provide coverage, would that be a reasonable expectation? Isn't the problem then perhaps policy and not technology?
It would be fair to argue for cheaper plans with a "poor coverage" discount.
But to halt future technology until every not-spot is dealt with does not make any sense.
