Can I send SMS text messages using all the different phone numbers of my US based users?

Question

All my users are in the United States. When someone signs up on my website they enter their cell phone number. Can I use the user's own cell phone number to send a SMS text message via twilio?

I was reading the twilio documentation about subaccounts and I couldn't determine if this was possible or not. They make it sound like you can only send texts using a narrow range of phone numbers.

Twilio evangelist here.

Today, you can only send text messages from phone numbers you've provisioned from Twilio. We've got a FAQ article that describes why.

You can make phone calls from either a Twilio provisioned phone number, or a verified phone number.

Hope that helps.
