Not to send (at least in the USA). A lot of carriers will let you send an SMS with email. For example, to "text" someone on T-Mobile you would send an email to their-ten-digit-phone-number @tmomail.net. For AT&T it's @txt.att.net.
Not sure how it is for those of you living elsewhere.
Also, that whole authentication thing is backfiring on people who use their phones. If your phone is lost or stolen, a thief can use SMS verification to reset passwords and access your bank accounts and such. Not too mention, the SMS messaging system itself is not very secure.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
