New apple watch set up by provider not able to connect cellular

I’ve reset both my phone and watch and fully updated the software. Had the EID number manually put into the watch by my provider but mine will not show that there is a sim, it says no ICCD or no SIM card with no provider. Because of this I am unable to connect to a cellular that is connected to my account. My provider have no idea what they are doing either and cannot understand what is going on. If you have figured out how to fix this issue please reply back it would be greatly appreciated.
