For many travelers, an eSIM is cheaper and easier to control than roaming, but coverage varies by country and provider.
Install it before departure while you still have stable internet, then activate it when you land.
A short city trip can work with 3 to 5 GB. Longer trips with maps, social apps, and calls may need 10 GB or more.
