Help! My Phone's Not Registered on a Network, I can only make emergency calls. 7.9.2024_HOUSTON WE HAVE A PROBLEM!

My Phone's Not Registered on a Network, I can only make emergency calls. I cannot even text. Can anyone assist with this matter? I am trying to work and difficult to do without being able to call out or receive phone calls from potential clients, family, and friends. Perhaps this is the Beryl Hurricane effects, but we had hurricanes before; however, I still could call out and receive calls. HOUSTON WE HAVE A PROBLEM!!! SERIOUS PROBLEM.
