Why is my phone unable to use my phone plan after newest update?

[Android Central Question]

I updated my phone today, 7/15/2020, and after I did I couldn't make or receive calls or texts. It was working fine before hand, and now I can't use my phone like a phone. Please give me answers to how to fix this.

What phone do you have? Was this a full OS update or was it a security patch? What carrier are you with? Have you checked with your carrier?
