Mobile plans are also on the cheap side, to the point of being competitive with many third world countries (for example, I wasn't that impressed with prices in Thailand in 2020 for comparable plans, only a 1-2€ difference with what I had at home).
This is getting to the point that I find myself often suggesting fellows from border countries open a line in France, just so that they can enjoy the "European roaming data envelope" that comes with most plans (i.e. several gigabytes are free to use from anywhere in Europe, and you can make calls and texts to other EU countries when abroad...) after realizing how expensive and suckish mobile plans are in their country (Belgium in this instance).
