Someone else is talking when I answered a call #iphone #philippines #smart

Hi everyone! Any of you ever experienced answering a call then someone else is talking and not the person who called you?

I’m from the Philippines, and I’ve experienced this twice already, someone called me and she said she couldn’t hear anything from my end. But on my end, someone else is talking in a language I don’t understand.

I’m using iphone 13 pro, and my network is Smart. Is it possible that there was just an overlap in the call lines or does my phone have a virus or something? This is really bothering me, hope someone could help. Thank you!
