why there's no mobile coverage within the tube? I tried to call a
friend but unsuccessfully.

I think the Laws of Physics have something to do with it.

It's the law of "trying to get someone else to pay for the installation".

Do you mean LU trying to get someone other than themselves to pay? If
so, damn right - LU shouldn't pay for such provision.

The reverse wasn't it? LU paying to have the infrastructure fitted so
they could talk to train drivers, and the public also using it being a
bonus.

Previous discussions have all revolved around the installation of BTSs
at stations only, and not in the running tunnels which would just add
an enormous extra layer of complexity and cost for little return (I'm
thinking of the deep-level tube tunnels in particular here).

They've managed it in the HEx tunnels.
