I got a text message asking me to call 877-364-2950. When I did, a "bank" wanted me to give them information to "reactivate" a credit card. Of course I don't have a card with that bank.
Reverse Look-up reflected that 877-364-2950 doesn't belong to anyone listed. It was another fraud scam.
I surely want to find a way to block text messages sent by e-mail addresses.
I'll note that it is a known issue for Sprint http://www2.sprint.com/mr/gp_dtl.do?id16=I_want_to_stop_spam_and_phishing_text_messages&article=680#__highlight they just don't offer any tools to block text messages from people not in your address book.
