Smartwatch with LTE or Smartwatch with Cellular Support

Smartwatches with LTE support or cellular support allow you to make or receive calls directly from the smartwatch. You do not need the paired smartphone for making or answering phone calls.

Cellular support requires an eSIM por embedded SIM functionality to connect to the cellular network or the LTE network for handling incoming or making outgoing calls.
