Who I have the same questioned this topic

My phone will not place or receive calls or text messages.  

I received and error message that stated "No Service Available."  But, my friend standing next to me with a Samsung S10 and Verizon as her carrier, had service and her phone worked!

Next error message to appear on my phone was "Not Registered With Network."  I have a Family Plan with Verizon.  How am I not registered or not receiving service from my Carrier?

Next error message was "Roaming Option Off."

I went to a Verizon store and purchased a brand, new SIM card.  I had the Verizon tech install it for me.

My phone still will not work properly.  Please help, if anyone can.  Thank you.
