You can equip the watch with an eSIM card, as the LTE version of the model supports eSIM. This means that the watch is connected via the mobile network independently of the smartphone.

The watch can also be used without a Samsung or other smartphone, as it is independently mobile-capable via the eSIM. However, a connection to a smartphone is usually required to set up and manage the eSIM, especially for activation and configuration.

The emergency call function can generally be used with an activated eSIM and mobile phone connection, even if the smartphone is not nearby, as the watch can make calls independently.
