Caller type: Unknown
Called my cell phone this afternoon. I didn't answer. I called back later to check on name of caller, and got message "this Public Wireless number is not available," and was switched to their voicemail. When they called me originally, however, they didn't bother to leave a message on MY voicemail! Therefore, either wrong number, telemarketer, or scam.
