Can there be crosstalk when sending text messages on mobile phones?

Yes, I am a mobile user. Two days ago, my mobile phone had a phone number in class every day, but it was a strange number. When I called back after class, the man said he didn't call me. I called my classmates three times. The voice of a strange man always scares me. Later, my classmate said that his number has not changed, and it should be a cross-line.
