why would anyone pay for this service when it is already free to send an sms text message to anyone's cell phone via outlook, or any other email client out there like yahoo mail, gmail, hotmail, etc.... all you have to do is send an email to "users phone number"@vtext.com for verizon wireless as an example. In other words, sending an email to 5555551234@vtext.com will accomplish this task for free without spending a dime.
