So as the title suggests, when I am in my house, my cell phone network connectivity is almost non-existent. I am connected to my home wifi, which is secure, and we have a mesh network extender throughout all parts of our home. The wifi is great. However, I cannot make or receive phone calls or texts often. Family often knows that if my phone goes straight to voicemail to either call 3-5x before it will connect, or call my spouse, whose phone connects with no issue.
I've done a full factory reset, and the issue persists.

So other than just complaining to VZW, is there some place on my phone that I can take tangible, repeatable data, to show them that i truly have no service?
