How does an eSIM work?
Instead of receiving a plastic SIM card, you install an eSIM profile on your device—usually by scanning a QR code or entering the installation details manually.
Once installed, your device uses the eSIM to connect to local mobile networks wherever your plan has coverage.
Your existing SIM does not need to be removed. On most compatible phones, you can keep your regular number active while using the eSIM for mobile data.
