I'd have to do a test run, maybe a month or so on the road here in Balkans, to see how it would work. Some planning is definitely required, but it seems like it should be doable.
Like staying in an area with internet coverage for a few days, to be able to work, and riding through remote areas on Fridays, Saturdays, and Sundays. Maybe reaching a spot with decent internet on Monday or Tuesday, and then just rinse and repeat.

Also, if you travel through countries that are less expensive than the EU and US, you don't need a ton of money.

For those areas that have some internet coverage, this seems to be a popular solution: https://soliswifi.co/pages/how-it-works

Ya, that's something you'd need a really good internet connection, to work without any issues. My work is a bit more forgiving in that regard.

That's true, and data is really cheap in India.
However, some very remote areas will be an issue, India is no exception. But in the cities, yeah, I had better internet than in Europe.

Yup, that's the idea. As said, planning is the key here, but it seems doable.

Staying for a couple of months in a place with a good internet connection, working and piling up on cash, so that you can have some slack for the next couple of months while on the road, where your connection might be spotty; that's also a possibility.
