Particularly when you live in a mobile-free zone like we do!
Maybe that will improve, for outdoor signal (e.g. external antenna) with the Shared Rural Network project: https://srn.org.uk/
A planning application is in for a mast to serve our community but it is now bogged down due to the legal departments of the County Council and mast developer becoming involved! No network has yet publicly stated that they will take capacity on the mast but we live in hope.
For the record, the County Council recently gave permission for a new mast elsewhere in the rural fastnesses of the county but only on condition that the mast has generator capacity on site so that the mast does not die in fairly short order. This is to avoid the situation where large parts of the county were devoid of communications for several days after Storm Arwen in 2021.
