Your post indicated your phone was ringing during class. If it's off, how do the students know you're getting calls?

Received a call from this number 1 minute ago. I have been receiving the calls for 2 days now randomly. No message left and I have not answered.

2nd call from this number in 2-3 days. Missed call, no voicemail, cannot return call. If anyone finds out who it is please post.

Considering the number is quite obviosuly spoofed, it's safe to say this is a scammer. NO area code or phone number prefix in the US or Canada begins with a 0 or a 1. If you ever see a number beginning with either of those, simply block and ignore.

(202) 039-XXXX is not valid. However, 202 is a valid area code. Check that you entered 039 correctly.
