Life is digital nowadays.

Hotel reservations, check-in and check-out are done online, tickets are online, etc.

How do you travel without using anything digital?

I didn't say I did travel without anything digital. My comment was a question about a degree of connectedness, not the existence of it.

On one hand you have your phone for solving some basic problems, on the other you have to be near reasonably reliable internet constantly, with backup devices and contingency plans for them.

That, I do occasionally find myaelf the opportunity to be completely without digital stuff, and find them quite relaxing.

I would do things to get a break from it, but the reality is you can't really escape when you work remotely. You are tied to that digital life as a basis for the travel itself, as well as the employment that affords you the opportunity to do so. I am not one of those people that's constantly on my phone, but for most of my travel I was in operational roles where I was on-call 24/7, and using my phone or similar devices for basic services while traveling like translation, maps, cars, train tickets, plane tickets, hotels, payments, etc.

What you describe is kind of what I suspected, in terms of that specific job requiring you to be that available, which is why the question was genuine. I also work remotely, and have at times travelled simultaneously, but never in the same way, unless it's the constraint I'm accepting because I actually don't have the vacation time. As in, if I'm in vacation, laptop stays at home, otherwise I'm just trying to do both and sometimes that's a fair compromise.

Even day to day living stationary, I have a hard time accepting that not being able to escape is a requirement, but I'm not really responsible for any critical systems, and am not paid like that either.
