How to Send SMS Messages for Free using GoLang

Are you looking for ways to send SMS messages without incurring unnecessary costs? With the rise of messaging apps and social media, sending text messages has become a crucial aspect of communication. In this article, we will explore how to send SMS messages for free using GoLang.

GoLang is a modern programming language developed by Google that has gained popularity due to its simplicity and efficiency. One of the key features of GoLang is its ability to handle I/O operations asynchronously, which makes it an ideal choice for high-volume and high-throughput SMS applications.

Traditional approaches to SMS have been to store messages in SMSC storage areas (e.g., message database) before forwarding them for delivery to the recipient's SME. However, this approach consumes a lot of memory and is notoriously difficult to program. In contrast, Node.js uses an event-driven, non-blocking I/O model that allows developers to write efficient, scalable code.

To send SMS messages using GoLang, you will need to establish a connection with an SMPP server. The SMPP (Short Message Peer-to-Peer) protocol is used by the telecommunications industry for sending and receiving short messages between mobile phone networks. The SMPP client takes care of the SMS and delivers them to the SMPP server.

The SMPP server transmits a delivery report back to the client when there is a change of status for an SMS. The SMPP client also issues unbind requests, enquire_link requests, deliver_sm requests, submit_sm requests, and bind requests to establish and maintain the connection with the SMPP server.

Using Node.js node-smpp library, you can implement the SMPP protocol in your GoLang application. This allows you to send SMS messages asynchronously, without having to wait for responses to earlier requests to be received. Requests are processed independently of each other, making it possible to issue multiple requests simultaneously.

In addition to its high-performance capabilities, Node.js also provides a persistent connection with the SMPP server, which eliminates the need for establishing new connections every time you send an SMS message. This makes it an ideal choice for high-volume and high-throughput SMS applications.

By using GoLang and the Node.js node-smpp library, you can send SMS messages for free without incurring unnecessary costs. This tutorial will walk you through the process of implementing SMPP protocol in your GoLang application to send SMS messages using your own SMSC gateway.

In conclusion, sending SMS messages for free is now possible with the use of GoLang and Node.js node-smpp library. With its ability to handle I/O operations asynchronously and provide a persistent connection with the SMPP server, GoLang is an ideal choice for high-volume and high-throughput SMS applications. By following this tutorial, you can send SMS messages without incurring unnecessary costs and improve your communication experience.
