An eSIM is a digital SIM card installed directly on your smartphone.
Instead of inserting a physical SIM card, you download an eSIM profile by scanning a QR code or using installation details provided by your eSIM provider.
Activation usually involves:
- Installing the eSIM profile
- Selecting it for mobile data
- Enabling data roaming
- Allowing the phone to connect to the local network
Before Activating Portugal eSIM
