SMS are created on mobile phones or personal computers. These devices send SMS with the help of a GSM network (Global System for Mobile communication). All the devices have External Short Messaging Entities (ESMEs).
ESMEs are the starting point and end-point of SMS. However, they cannot communicate directly. The starting point – the source sends SMS to Short Message Service Center (SMSC). The SMSC Gateway is the entity in charge of storing and forwarding messages to and from mobile stations. The ESME can be a fixed network or a mobile station that receives and transmits messages.
Further, for completing this process of sending and receiving SMS, you need a protocol, such as SMPP, SS7, SIGTRAN, SDP, and HTTP protocols. Here, we will discuss the SMPP Protocol.
SMS Gateway that uses SMPP Protocol is known as SMPP SMS Gateway. Let’s learn all about SMPP Protocol.
What is an SMPP Protocol?
The SMPP (Short Message Peer-to-Peer) protocol is an open, industry-standard protocol that was created to offer a flexible data communications interface for the exchange of short message data between External Short Message Entities (ESME), Routing Entities (RE), and Message Centres (MC). SMPP gateway open source is a method for apps to send SMS messages to and receive SMS from mobile devices.
What are SMPP sessions?
An SMPP session must be established between the ESME and the Message Centre or SMPP Routing Entity to use the SMPP Protocol.
- Transmitter (TX) – An ESME who has been authenticated as a transmitter may send brief messages to the MC for transmission to Mobile Stations (MS). An ESME can also cancel, or replace previously sent messages during a transmitter session. Messages delivered in this manner are frequently referred to as mobile terminated messages.
- Receiver (RX) – An ESME can receive messages from the MC using a receiver session. These communications are known as mobile-originated messages because they are frequently sent from mobile stations.
- Transceiver (TRX) – A TRX session is a combination of TX and RX, allowing a single SMPP session to send mobile-terminated messages and receive mobile-originating messages.
How can businesses use SMPP?
Businesses use SMS services for many applications that go well with SMPP Gateway.
- Businesses send promotions to their customers for marketing.
- The hospitality industry sends booking confirmations via text messages.
- The financial industry and taxis send Two-factor authentication / OTP to verify the customer’s identity via text messages.
- Banks use them to keep aware of customers’ account activities.
- E-commerce stores send order confirmation, tracking details, sale alerts, etc., via SMS.
Why should you choose Telnxo?
Here are compelling reasons to consider Telnxo as your SMPP gateway provider.
- Scalability – You may want to grow your firm in a few years and may require effective SMS campaigns. You can partner with us for your massive campaigns.

You may be interested in knowing the number of messages delivered, the number of clicks from the messages to better understand the CTAs, and various other statistics to make the necessary decisions. As an SMSSMPP gateway provider, we share all these statistics.
In final words, the SMS gateway requires a protocol like SMPP to run the entire process of sending and receiving SMS with SMSC gateway and GSM networks.
