I received a text message from this number, as well as from 2 other different numbers......all 3 texts had the same message "Thank you for your loyalty, now you can upgrade your device at no cost, please visit https://tr....."  (I won't put the complete website, as I feel certain it is some sort of a malware site).  I did not go to the site, but am sure it's not from my cell phone provider..... the two other numbers I got the same message from were 413-281-7327 (which actually shows up as a doctor's phone number on reverse look-up search engines), and 781-733-4880.
