Most carriers have “SMS gateways” which take email messages from the Internet and deliver them to their customers’ cell phones as SMS text messages. The trick is that you need to know what carrier the recipient’s phone is on. It’s not enough to know their phone number.

That’s why, the carrier determines what email address of the receiving phone is going to be. For example, Cingular phones’ address are all “number@cingularme.com” while Verizon phones are “number@vtext.com.”
