Apple Watch cellular

Hi Georgejrrae,

Thanks for posting in Apple Support Communities.

We understand you're unable to use your Apple Watch abroad. Make sure that you have Data Roaming enabled on Apple Watch Settings > Cellular. Also, check with your wireless carrier that this feature is enabled on your Apple Watch cellular plan.

International roaming with your Apple Watch

With watchOS 9.1 and later, international roaming is available on cellular models of Apple Watch Series 5 and later, Apple Watch SE and later, and Apple Watch Ultra. 

To get international roaming on your Apple Watch, contact your iPhone carrier to add your watch to your iPhone cellular roaming plan. For international roaming to work on your Apple Watch, your carrier must support VoLTE and roaming. Not all carriers support international roaming on Apple Watch and coverage in other countries is determined by your carrier.

To turn on international roaming, open the Settings app on your Apple Watch. Tap Cellular, then turn on Data Roaming.

You can find these steps in Set up cellular on Apple Watch - Apple Support.

Regards.

Salutations Georgejrrae,

Similar to iPhone, there are different models of Apple Watch and they aren’t all supported by every carrier in the world. This article goes over the different models and which carrier(s) and region they are compatible with - Apple Watch - Carriers

Thanks.
