Android Messaging: Staying Connected Without Cell Service
Imagine your phone can still send messages even if you have no cell service.
Android phones can use Wi-Fi, like at a hotel, with something called RCS messaging if you have Google Messages.
It's like regular texts but uses Wi-Fi.
If you're hiking somewhere with no signal or Wi-Fi, some new phones have a special feature called Satellite SOS for emergencies.
If you need help, your phone can send a message to emergency services using a satellite.
This is only for emergencies.
