Apple Watch Ultra - No SIM, No Connection

[Dedelebentq]

Has your Apple Watch's cellular suddenly stopped working after being set up? It looks like this issue is affecting a lot of users. I searched online but couldn't find a solution until now. Here's what worked for me:

1. I turned off my watch and turned it back on.
2. I updated my iOS software
3. I opened the Watch app on my iphone, went to "Cellular" and clicked on the "i" under my cellular plan. I removed the plan
4. I added a new plan (it was the same as the original plan)

Problem solved!
