I got a phone call today from a random number. The guy said that he had a missed call from my number and he was calling back. I had 100% not called this number, and it has happened on a number of occasions with different people.
Its pretty obvious that the person on the other line is not a scammer as the conversation usually ends pretty quickly when I say I didn't call their number.
So I'm trying to understand what's happening here. Have I been Sim swapped? How did they receive a missed call from my number where my phone has no evidence of making the call. My bank account and everything else seems to be fine. I have pretty good passwords on my email and other accounts.
Any idea what's happening here?
