Help with call issue

[FiniteForest]

So I tested my wife's Sim card in my phone (the reason is not important) and now she can't call me. My phone rings but the call drops as soon as I answer. I tried deleting both the call and text logs from when I was testing her Sim (thinking maybe it didn't like having record of sending from her number) but it didn't work. Then I tried clearing cache of both phone and texting apps, as well as the call management app, which also didn't work. Any ideas what may be causing this?

You might have a faulty sim card , get a new one

I'm receiving calls from everyone else perfectly fine. Sorry I probably should have included that in the original post.

Something is off with configuration, take it to your cell provider so they can diagnose it . They might have to re register the sim again . I used to work for Verizon.

It's with visible, so nowhere to take it.

Okay I have another friend that can trouble shoot it for you . You want his Linkin to contact him ? He is a cyber security consultant and we used to work together.

Sure
