Many people do not realize their cell phone and PDA device can receive text messages by sending an email to their services provider's SMS gateway.

Although message delivery is not as reliable as direct wireless communication using an SMS provider, SMS gateways allow all cell phones, PDAs and Blackberry devices to receive Notify.com communications, without the per-message cost associated with SMS providers.

Sending text messages to cell phones and PDAs using the free services of an SMS gateway is a popular choice for non-critical Notify.com communications.
