eSIM smartwatches
31 models are listed on this page. Check the columns to compare them.
An eSIM watch can use a cellular plan without a physical SIM card. It still needs a plan from a carrier that supports it, and many need a phone of the same brand to set up. The table lists each eSIM model with its connection type, operating system and phone compatibility.
