After you purchase a plan, SimSIM sends a QR code to your email. You scan that code to install the eSIM profile onto your phone. Do this before you travel — once the profile is installed, the eSIM activates automatically when you arrive in the destination country and your phone connects to the local network.
Install your eSIM before you leave home. You need a Wi-Fi or mobile data connection to complete the installation. Do not try to activate at the airport without a connection.

Download and install the eSIM profile

Follow the on-screen prompts to download and install the eSIM profile onto your device.

Configure your data line

Travel and connect

Head to your destination. SimSIM connects to the local network automatically when you land — no manual switching required.

​
Setting your data line

After installing, go to your phone’s SIM settings and set SimSIM as your data SIM. Keep your regular SIM active for calls and texts so you don’t miss anything while you’re away.
