Apple Watch Series SE (2021)

Apple Watch SE (GPS + Cellular) can use a cellular connection for Emergency SOS. However, if the iPhone isn’t nearby, the Apple Watch needs to be connected to a known Wi-Fi network, and Wi-Fi Calling must be set up.

The international emergency calling feature requires an Apple Watch SE (GPS + Cellular) model. Supported countries and regions can be found on apple.com/watchos/feature-availability.

Family Setup:

Not all features will be available if the Apple Watch is set up through Family Setup. A wireless service plan is required for cellular service.

Network Connection:

Connection may vary based on network availability. International roaming is not supported. Participating wireless carriers and eligibility can be checked on apple.com/watch/cellular.
