A notice can be sent to your SMS-Enabled cellphone when you receive a request for information. This works by sending an email to your phone using a special email address provided by your cellular provider. The length of these messages is limited to 160 characters, so not all of the information from the request for information form will be included. This feature is enabled by entering your SMS email address. To disable this feature leave the SMS email address blank.

Here is an explanation of SMS from Wikipedia: http://en.wikipedia.org/wiki/Short_message_service

Your SMS address is usually your telephone number @ your service provider's messaging gateway.

If your cellular provider is not listed, please contact them directly to determine your SMS address or go here: http://en.wikipedia.org/wiki/SMS_gateway
