An eSIM is a SIM card that is embedded in a mobile device and can connect you to any valid operator to offer eSIM services. The eSIM works the same way as a traditional and local SIM card, but you don’t need a physical and regional SIM card to delivery and use it. It is actually pre-installed and prepaid in the device, and you can activate it by installing your “eSIM account” coverage of a new pro operator without talk.

The eSIM is similar in principle to a physical SIM card technologies. However, in the case of eSIM, all your data is sent via the Internet without providers using a QR-code. It doesn’t require physical presence.

The steps to switch to the eSIM:

  • Order the smart eSIM plan from our website or app.
  • You’ll receive a QR-code and additional information by email or generated on our website/app.
  • Scan the QR-code or enter the information to activate your eSIM.
