Last summer I started getting random calls on my Virgin Mobile phone from strangers (not telemarketers). Each was from a different number, mostly were local. Many were at early hours in the morning. A few left text messages or voicemail. Then they switched to mostly Spanish or Chinese speaking callers. I always let them go to voicemail and never called them back. They gradually stopped calling. No idea how they all got my number or if it was a glitch in the system.
