The 1st call came in on my mobile 03/31 and a 2nd call 04/03 at 1002 A CDT. No Caller ID info and they left no voicemail 03/31. Since the 214-041 NPA-Nxx is an UNASSIGNED code group, the caller is most likely some kind of SCAMMER. I blocked the number on my Windows10 Smartphone after the 1st call so my phone never rings on subsequent calls.
