Exactly. And delivering “text” messages is pretty easy.
I belong to a CERT group that was formed after an early year ice storm that ravaged Western New England about ten years ago. We can set up and relay messages from the NY Border to Boston. Letting someone know you are alive and well (or hurt and need help) saves lives and reduces panic.
And that is the service for amateurs to do regarding Emergency Communications that ARRL keeps pushing. That is an important community service and does more than what they can do getting in the way of First Responders.\
Cell serivce will be up with tower trailers, etc. and it is for those very First Responders—not for normal folks—not at first.
But sending out emails or texts to loved ones via radio is a very important sevice during times of disaster.
