Yes, if you buy a lovely granite house or cottage signal is much reduced, its not unusual to see phones perched on window frames as that's the only place in the house you get a signal, people then run outdoors to answer a call.The only area with 5g currently is Truro, that's it, 4g elsewhere and drops to 3g in outlying areas. In certain valleys and coastal areas there's no signal at all. I have taken short breaks in Hayle, Boscastle, Bude and on The Lizard and have had huge problems finding phone signal.
I have fairly good internet, but I have fibre installed, was the first in the street and I know there's a waiting list now nine years on, the telegraph poles/exchanges don't have the capacity to provide fibre to every household. You can't get cable services here, I mentioned the irony of years of upheaval due to cables being taken up country, but we were completely bypassed in a previous post.
Trains have reverted to the 1970's, we might have shiny new things but they often don't have catering on them down into Cornwall. It used to be Plymouth where the catering came on board, so two hours into your journey you could get a hot drink. Same coming home catering would get off at Plymouth, at least in those days you visited the catering car and fetched yourself a drink before Plymouth. We had a short space of time when the trains arrived in Cornwall of catering on board from its originating station and all the way back again, it was bliss! Nowadays, you're incredibly lucky if there is a catering trolley on board at all and more often than not you won't see it in your carriage before it gets taken off. On a recent trip I jokingly commented that it was like going back to the 70's where everything came off and back on at Plymouth, I actually thought the issues were down to strikes and a lack of staff currently. GWR staff informed me that actually trolley services were planned to be based in Exeter and another station I can't remember.. might have been Taunton! I was shocked, we waited years for new trains as we always get cast off's from other areas and now we've got them we get some half arsed service to boot.
We Cornish can take the mick out of ourselves, a lot of posts are tongue in cheek for if we didn't laugh we'd cry. Since we left the EU Cornwall has lost a huge amount of funding and things are only going to get worse and to boot the Government are trying to make us have a Mayor!
Train not stopping Camborne Wednesdays is a famous Jethro joke, he'd probably add Hayle into that joke nowadays too.
