Android telephony and telecom

How do you know if someone has a second number? My boyfriend's activity history as using Android telephony or Telecom but no calls show or messages

I'm going to answer the question you asked, by answering the question you didn't ask: We can not help you spy on your boyfriend's activities. That's an invasion of privacy and illegal. If you're having that kind of trust issue, that's something to take up with a counselor. A phone tech forum isn't the place for that.

Android Central does not permit any discussions of spying on other people. Thread closed.
