@Morghur @Niloy005 @MMS21 Honestly i would probably just use a LoRa communicator if i need to contact my children. It has an about 500 mile range and isn't reliant on cell service.

Even if your just a layman, i don't understand why parents don't get a jitterbug or dumb-phone. Even as a kid i was happy playing around with my grandmother's old Motorola phone.
