An eSIM is a digital SIM built into your phone. Instead of inserting a physical SIM card, you download a mobile plan and activate it from your device settings or a provider app.

Often, yes. Roaming can be expensive and unpredictable. An eSIM plan is prepaid, so your cost is typically more predictable and easier to control.
