Applewatch
Is the Apple Watch SE supported by Tesco Mobile?
Question marked as
Tesco suggests you are in UK. The only UK networks supporting a cellular service for Apple Watch are EE, O2, Vodafone and only to their direct customers. The virtual networks who resell bandwidth on the big 3 don’t support Apple Watch. However, you can link a non cellular watch (GPS model or unconfigured cellular models used over Bluetooth) through your iPhone on any network, the network doesn’t care.
