SMS Delivery from Web Applications Using PHP

Question:

How can I send SMS messages from a PHP web application? What are the essential steps involved?

Answer:

While there are numerous commercial services that provide SMS delivery, an alternative approach to consider is leveraging email-to-SMS gateways. Many US cellular carriers assign an email address to each phone number, allowing text messages to be sent by emailing the designated address.

For example, if the user's carrier is AT&T and their phone number is 786-262-8344, an email can be sent to [email protected] to deliver a text message with the email's subject and body as the message content. This service is typically free of charge and covers a wide range of US carriers.

While this approach may not fulfill all application requirements or be suitable for every use case, it offers a potentially cost-effective and convenient option for basic SMS delivery.
