SIM stands for “Embedded Subscriber Identification Module”, and is a revolutionary technology that enables the activation of a cellular plan without using a physical SIM card.
The eSIM works the same way as a traditional SIM card, providing the necessary identification and connectivity features for mobile devices.
The distinctive aspect of eSIM is that it comes pre-installed in the devices. Users can simply activate the eSIM by scanning a provided QR code, bypassing the wait for SIM card delivery and eliminating the need for physically swapping SIM cards. This innovation offers enhanced convenience and flexibility in managing cellular plans for modern mobile users.
You can make a purchase anytime at your convenience. You may purchase an eSIM plan the day prior to your travel date or upon arrival at your destination.
To activate the eSIM plan, your device must be connected to a cellular data network or Wi-Fi. We recommend that you activate an eSIM plan by using a public Wi-Fi network like those available at an airport or hotel.
There are 2 ways to add an eSIM to your device (please note that these steps may differ depending on your device & language.)
To activate the plan, you need to be connected to a strong WiFi signal and not in airplane mode.
