SIM Incorrect Activation/Unable To Activate Watch

I upgraded my iPhone 11 Pro to a iPhone 12 mini and during that upgrade I received a new SIM card. Well the SIM card did not activate properly and my old SIM from my iPhone 11 is the one that's active. These changes do not reflect properly on my account and because of this I am unable to activate my Apple Watch. During the watch activation I can not get past clicking "Get Started" during step 1. It just returns a message that says "Sorry, looks like we are having technical difficulties. Please try again." I have done every type of unpair and reset imaginable.
