Apple Watch Series 8, Apple Watch SE and Apple Watch Ultra GPS + Cellular models with an active service plan allow you to make calls, send texts and so much more — all without your iPhone. You can complete a call to emergency services even when you’re travelling abroad just by pressing and holding the side button.1
To cover the LTE and UMTS bands used around the world, there are two separate GPS + Cellular models for Apple Watch Series 8, Apple Watch SE and Apple Watch Ultra. They have been optimised for use in the country of purchase, and not all models work in all countries or regions. There is no single model that supports mobile service worldwide. To see which carriers in your country or region offer mobile service for Apple Watch, refer to the chart below.2
Check with your carrier to see if your iPhone plan is eligible for Apple Watch mobile service. If you have an enterprise or corporate mobile service plan, check with your company or carrier to see if they support this feature. Prepaid accounts and some older accounts may not be supported.
