Wifi direct is becoming popular and makes this kind of thing possible. I've also seen hardware products for similar like the gotenna. You could have a party of people across a relatively large area (say a ski resort, trail network, or neighborhood) and have decent async connectivity for SMS like use between them.
Software products like Lifenet, Firechat, Bridgefy, and similar generally use wifi-direct or bluetooth to communicate and do support store and forward.
On the amateur radio side js8call does allow forwarding through 3rd parties and store and forward.
Granted the financial model for these kind of things is tricky, but they do seem to be getting more popular. But sure I don't expect any cell provider to help, and was pleasantly pleased when p2p/direct connections was added to android.
I was pretty interested in gotenna and wanted to add a DHT and internet gateway so that messages would be delivered globally if anyone in your mesh had an internet connection. They rejected my idea 8-(.
