An eSIM is a SIM card that is embedded in a mobile device. If you have a device equipped with an eSIM, you will be able to install an “eSIM profile” on it and enjoy the connectivity offered by providers.
Your device must be unlocked by the carrier from which you bought it to be able to install any eSIM profile on it.
Please note that some devices are equipped with an eSIM, but you will not be able to use it, whether your device is locked or unlocked, as this eSIM feature can be restricted for some markets/countries. For more information about your country, we advise you to contact the device manufacturer.
