I'd give her the phone. What can of worms? If she is riding 20 miles ... and, Marathon Plus tires don't flat. They simply don't. Case closed. Give her a phone anyway. There are PLENTY of things that could stop a ride besides a damn flat. Or don't let her ride anywhere. Drive her everywhere she needs to go yourself.
