Not recieving texts/calls consistently

[CHRLEN56]

My Galaxy S9 on Verizon is not receiving texts or calls consistently. This has been happening periodically but is getting worse. I can receive some phone calls, but many times someone will call and my phone will not ring, nor will I get a missed call notification. I am also not always sending or receiving text messages on a timely matter. I can send a text and it says sent but the recipient will not receive it for several hours later. Same with receiving; contacts will tell me they sent a text and I do not get the text until much later. This is happening from quite a few different people who have a variety of different phones and cell providers; my phone appears to be the issue. Any assistance would be appreciated.

This started happening at least 2 months ago, possibly longer. My phone is backed up and running the most current software.
