eSIM and Data Roaming Explained

What is Data Roaming?
Your phone connects to foreign networks through your home carrier. You get charged extra — daily, per MB, or via a travel pass — often with hidden costs from background app updates and incoming calls.
What is an eSIM?
A digital SIM embedded in your device. You buy a travel plan online, activate via QR code, and get local or global data at a fraction of roaming prices. No physical SIM swap needed.
