Unlike smartphone eSIMs, Galaxy Watch 4 uses a carrier-controlled wearable eSIM system that depends on local telecom support. This means you usually cannot install any eSIM provider freely on the watch. Activation often requires a supported carrier, regional availability, and Samsung wearable provisioning.
Samsung Galaxy Watch 5 does support eSIM, but only on the LTE version. The Bluetooth/Wi-Fi model does not support cellular connectivity or eSIM activation. This means if you want standalone calling, mobile data, or phone-free usage, you must choose the LTE model.
