geekiegeek: So I went through the setup and it said it succeeded. The plan shows in my Apple Watch mobile settings but it won’t connect. Have tried restarting the watch but still no go. Any ideas?
It won't be you or your watch, it'll be Spark.
JonoNZ: Note that if you are a Spark Digital customer you need to get them to add your One Number Plan for you and provide the Apple Watch EID and IMEI to them.
Phone and watch have individual IMEI numbers which the Spark network needs to know to share on one number/account.
