How can I fix my Apple Watch Ultra 2's "No Connection" issue?

My previous Apple Watch had the same problem at one point, no cellular connection, NOBODY could fix the problem !

So here we are my Ultra 2 doing the same thing again, no connection.

Of course I did multiple Reboot, Reset, Un-Pair/ Re pair both the watch and the iPhone

Without any succes.

Contacted Rogers Support, they open a ticket, Of course we went through, multiple, Reboot, reset un-pair/ re-pair etc.

Please find a solution

Watch OS, 11.5

IOS, 18.5

Thanks
