Once we are on the road, there will be occasional stops and, considering our tendencies towards off-the-grid nature, it is quite probable that we won’t be able to use our cell phones, and why should we?
A simple invention, much older than mobile phones, takes care of all our needs in that regard. Hand-held, portable, two-way radio transceivers, otherwise also known as walkie-talkies.
I got us a couple of weatherproof Motorola TLKR T80 Extreme two-way radios with a maximum talk range of 10km. We can use cell phones to communicate with others if or when it is needed, but for all communication between the two of us, this should more than suffice.
Incidentally, Motorola has been involved in walkie-talkies since the beginning of time! Walkie-talkie-time, at least. The first two-way radio transceivers were developed during the Second World War. The development is credited to Donald L. Hings, radio engineer Alfred J. Gross, and… the engineering teams at Motorola.
