What is a SMS gateway and how does it work?

An SMS Gateway allows a computer to send and receive SMS text messages to and from a device -- usually a mobile phone -- over the global telecommunications network. The SMS Gateway converts data into compatible format so that it can properly reach the destination. Modern SMS Gateways use SMPP, or Short Message Peer-to-Peer protocol, to distribute SMS traffic to the Short Message Service Centers (SMSCs) of a mobile network.

What is Telnyx’s role in this process?

Computers can communicate with SMS Gateways through a REST API, like the Programmable SMS API that Telnyx offers, which is an application program interface that uses Hypertext Transfer Protocol (HTTP) to send and receive messages.

What is a REST API?

A REST API is a special kind of application program interface, created by developers using a set of rules called “Representational State Transfer”(REST). An API is an interface that uses HTTP requests to pull and push data to other sources, allowing for communication between software programs.

What is a SMS gateway provider?

A SMS gateway provider, otherwise known as a SMS service provider, acts as the middleman between mobile networks and SMS service users by offering an interface for people to send and receive messages. Telnyx’s interface is easy to use, scalable, and includes powerful programmable features for enterprise grade SMS applications.

How do I use Telnyx as my SMS service provider in PHP?

Telnyx’s SMS API comes with 5 SDKs, including PHP, Python, Java, .NET, and Node. These API wrappers, combined with comprehensive API reference docs, enable a quick go-to-market- process for your application. Read more on how to get started with these SDKs in our Developer Docs.

How do I replace Twilio with Telnyx as my SMS gateway?

We’re glad you asked! We support easy migration from Twilio with our new Twexit API, which allows you to switch to Telnyx simply by making a couple of minor changes to your existing Twilio code.
