Who called from 6164993061

I have been getting many texts from many variations of "boa###@infos.com" and "boa##@infos.com."
I am a Sprint user and was told to send the phone number listed in the text to "7726" via text, and to report it to "[email protected]."
All the texts read the same with different phone numbers: "Good Day: Call .... Attention Required"
Numbers in texts so far include 205-561-2208, 616-499-3061, 773-912-1434.

Looking at one of the discussions on 727-216-2029 ( one of the other numbers they text as a call-back number ), these appear to be targeted at the 512 area code (Austin, TX) with a high percentage of Sprint users.

Also targeted to Sprint users in DFW. I got two texts this morning. One from 616-499-3061 and one from 347-410-5895.

I just got a call like those described...good day, call #, attention required.  I am a Sprint user in the Dallas area.

Okay... We are all getting them.  No more "I got 3 today" posts!  How do we stop them?
