For the past year, I've been getting random calls and texts from a lot of unknown sources. Many times the callers even spoofed different numbers. And sometimes people call me because they said I called them. I suspect phone user information has been leaking probably in many different ways.

Those are likely simple robo scam calls. Robo dialers call an absurd amount of numbers on various schedules in something of a brute force social engineering scam. To keep their dialers from getting permanently blocked or reported easily, they spoof the caller ID (usually with an area code similar to the recipient's area code in the hopes that someone will be more likely to answer a call from an unknown number if they think it's local), which is why you will sometimes get texts or calls from people who ask you to stop calling them. These kinds of people are just other recipients of spam calls and your number happened to be the number the robo dialer was using as a spoofed caller ID for them; that kind of thing doesn't really have anything to do with leaked info.

This is the benefit to holding a phone number for an area code that's far away from where you live. I can spot and ignore those calls easily.

How about in the cases that they have personal info in sms messages or voicemail? Info got picked up from somewhere?
