No, this is my first watch. I've not been able to connect to any network as of yet. I just get the error I mention below.The watch did have a non removable sim with its own sim number. ( Not a phone number. )
Were you able to make phone calls just using your watch? What about data? If I turn mobile networks on on my watch I get a sim not provisioned mm#22 error.
The TLDR of it is, There is a problem, nobody has been given a reason as to what or why it's happened. PM is aware of said problem and are working slowly to fix everything up again. The wait time is at least 4 hours for some people.
