A SIM-enabled smartwatch has a dedicated slot for inserting the SIM and an internal antenna for connecting to the cellular network, so you can make calls like a regular phone. Calls can be initiated using the voice assistant, by opening the app Contacts on the smartwatch, using the SIM address book or synchronizing contacts from a phone.

There is no SIM slot on newer smartwatch modelsbut is exploited for the purpose a eSIM modulewhich is a programmable SIM chip integrated inside the phone and able to emulate the functioning of the physical SIM.
