Issue With CFMAIL to SMS

I am having issues sending an email using cfmail to SMS. Verizons gateway is number@vtext.com. I have tested this by using my email program (outlook) and send an email. It came right through and I recieved it on my cell phone. When I try and use the cfmail it does not go through. Below is an example of what my code looks like

<cfmail to = "9991234567@vtext.com"
        from = "email@DoNotReply.com"
        subject = "test">
test2
</cfmail>

If you change the to address to my email address it comes through. When you put it as the cell phone number@vtext.com nothing comes through. I have also tried adding a try and catch statement but it does not see any issues and seems to go through however I dont get a text. This same code use to work on an old website of mine. Has something changed on the cell phone providers for this not to work? I have also tried sending to a tmobile number and gatewat and that didn't go through either.
