We find we don’t need cellphones to talk to each other inside the TC. :D Sometimes, I guess we make nonverbal cues though.
Seriously though, I use a Wilson portable signal amplifier at times. We’ve found that each cellphone has slightly different radios even with the same carrier. My Samsung Note 10 has better coverage with more channels than my wife’s iPhone 11 Plus. In the previoius generation, her iPhone which was a bit newer than my Note at the time, and the iPhone had better coverage. Fwiw, that matches what I’ve read in that the newer Samsungs have very good cellphone radios.
I have a whole house amplifier that I might hook up in the TC. From what I found at home, it overdrove the signal which didn’t help the coverage at home. So, we don’t use it. Keep that in mind that an amplifier might/might not help.
Just a word if you feel like mentioning it to elected representatives ... encourage more cell towers over more wired networks in rural areas. In many rural areas, it will always be cost prohibitive to run wires to every house. However, well placed towers could cover a lot almost impossible space for calls/internet. The side effect of providing interent in these rural areas via cell towers is that dead spots would disappear for calls/texting for those passing through.
