Cellular data stopped working after iOS 17.6.1 update on my iPhone

I started having issues with connecting in my office and with .75 miles from my office, about two weeks ago. I cannot call, text or use data. I get incoming texts but can't reply. I get mail notifications but they don't actually load. I cannot use internet at all.

My provider keeps telling me there is no issue and if I can't connect, I should use wifi (no wifi in my car, thanks). If it is the recent update, I hope they fix it soon.

I had a problem with Wi-Fi after 17.6.1 update. I finally realized that I had an unused, offloaded security APP on my iPad. Look in your settings to see if you have one. After I deleted it my Wi-Fi started working immediately.
