I have an iPhone 13 Pro Max and occasionally (quite frequently), I experience an issue during phone calls. The voice on the other end sounds robotic or similar to a dying battery in a Walkman. The audio alternates between normal and distorted robotic sounds. Has anyone else encountered this problem, and if so, how did you resolve it?
I'm with Tangerine mobile network and haven't contacted Apple support yet. I already spoke with Tangerine customer care, and they suggested it could be a device issue.
Apparently, this has happened with many of them (https://discussions.apple.com/thread/253638662)
Is it the same person or multiple people? And why don't you contact Apple support since they are literally the best people to help you?
