The data situation in Europe used to be a patchwork nightmare. Buy a SIM in France, cross into Italy, lose your connection. Repeat at every border. The EU's roaming regulations improved things for people with European numbers, but for visitors from outside the EU, the border problem was real. An eSIM with multi-country coverage solves it in one purchase.
We've crossed European borders by train more times than we can count — overnight trains, high-speed rail, border crossings where you're in three countries in a day. Having a single data plan that switches automatically to a local network in each country is not a luxury; it's genuinely useful. Here's what gives you unlimited data across the whole continent without the complexity.
