How To a Send Text to a Pager
Although pagers can't send out information, it is possible to send a text message to certain pagers using email, as long as the message is short and the pager has the capability to accept and display text messages.
Find out the pager's number and service provider, if you don't already know it.
Look up the pager service provider's format for email addresses. With most service providers, the email will be (10-digit-number)@(serviceprovider.com), but .net is also used with some providers. With this information, you can figure out the email address for your pager.
Log into your email and click "New Message."
Type the pager's email address into the "To" field of your email form.
Type a short message into the body of your email form. Try to keep it under 160 characters, as you would when typing a text message.
Send the email. The pager will receive your message as a text.
