Different lifestyles. When I’m in the middle of a field at 10pm in North Dakota and a trucker texts me that he is lost and he can’t find me to pick up a time sensitive load of bees I’m glad I have the ability to get a text even though the signal is not strong enough for voice. Same when I or my Son get stuck in a field and the nearest farm house is far away it’s nice to be able to text and get help. When I’m in an area that has only SOS capability it’s nice to know I can get help. Only had to use this once for someone I came across in the middle of nowhere Nevada. I was able to contact the Sheriff to come out and help them. 2 hrs in any direction to get cell service or find internet connection for a computer. Sounds like you have a great setup for your home. Unfortunately I do business with people all over the country and I spend a lot of time in rural areas where there is no wifi capabilities except thru a smartphone. I have an iphone 8 and had to upgrade from my iphone 5 because the battery died. Luckily my eye site is still good enough and I don’t have arthritis and can still cope with a small screen.
In that case, I'd use a small 5G capable laptop so that I wouldn't have to deal with the limitations of the smartphone. As for being in the back 40, that's what walkie talkies are for.
