Thankfully, in this regard, major carriers support VoWiFi, a way to do Voice and SMS over WiFi, which has improved this problem a ton.

I can do voice calls over WiFi, but SMS does not seem to ever go over Wi-Fi. Because I am rural and connection is so valuable, I carry two phones, one on Verizon, one on ATT+TMobile. Both are iPhones, but one of them is about 4 years old.

(If anyone has any hacks to get on FirstNet, I’d love to hear them)

Incredibly weird, I have the same issue with bad cell reception in a lot of parks, so I tend to go into airplane mode and can send and receive SMS on T-Mobile‘s network with VoWiFi just fine. Have you tried reaching out to them?
