@aspirin624 - You might not have internet access when traveling in a country where your operator doesn't have a roaming agreement.
Btw..
I travel frequently between Belgium and the UK via the Netherlands. While in Belgium, I can download offline maps, but that option disappears after I’ve been in the UK for a few days. Right now, I’m in the UK and can’t download any offline maps; I can only plan a route when I’m online.
And if you recall, the UK left the EU, so most network operators dropped their "Roam Like at Home" services, meaning travelers now have to pay extra for international roaming. 🤷🏻
