Can you put a SIM card in Galaxy watch 4?
Does a smartwatch need a SIM? No, you don’t need to insert a SIM card into your smartwatch in order for it to work. Samsung Galaxy smartwatches operate using something known as an eSIM. No calls, messages, or health data can be routed to iOS. The same restriction applies to both Galaxy Watch 8 Bluetooth and Galaxy Watch 8 LTE versions. LTE cannot be activated with an iPhone because the eSIM flow requires the Android Wearable app and carrier plugins.You do need a phone at first to set up the samsung galaxy watch 7 lte, but after setup, the lte version can work on its own. You can make calls, send texts, and use data without having your phone with you.
