there are sites that offer to send sms for free. How do they do it? how do I send sms programmatically?

A:
The sites that send SMS for free usually use the email interface that most of the carriers implement which allow you to send an email to (for instance) <your 10 digit number>@mobile.att.net
and have it received as an SMS by that phone.

Send an email to the 10 digit phone number @ Carrier's domain name.
Here is a list of the carriers and their domains:

is this a reliable way to send sms?

I doubt it. I certainly wouldn't do that for a production system.

in the free SMS API list, for some carriers there are multiple email addresses, for example: T-Mobile [email protected] [email protected] do I distinguish them?

A:
I use an SMS gateway and it is fairly easy but I did consider this as an alternative because it potentially gave me more control email to sms
