Apple Watch (Series 5) was paired to iPhone 8 +. Since restoring phone from back up watch is only pairs to phone when phone is on Wi-Fi. As soon as I leave the house I get the red rectangle with the red line.
Apple Watch Series 5, 9
Hey there gerryfromsurrey,
That is a strange issue to occur, especially since you're still able to pair both devices while your iPhone is connected to a Wi-Fi network. We'd like to help by providing an article that shows what to do next since your Apple Watch does show it's disconnected while your iPhone is only using cellular: If your Apple Watch isn't connected or paired with your iPhone Please keep in mind that one of the last steps listed would be to contact Apple Support.
Cheers!
Thanks bruno75. Appreciate your response. Apple Support assistance solved the issue.
You are very welcome, gerryfromsurrey, have a good day and thanks for using the Apple Support Communities!
