Linking Apple Watch Cellular to a secondary iPhone
I'm living in South Africa but working for a US company. My main iPhone therefore is on a US AT&T contract but it won't allow my Apple Watch to connect to AT&T in South Africa.
I get a message saying "This Apple Watch does not support AT&T cellular in this region".
How can I keep my Apple Watch linked to my main iPhone (US AT&T number) and then link the Cellular to a secondary local iPhone (South African number)?
Apple Watch Series 5, watchOS 7
