Send SMS with SMPP using Java

The jsmpp library can be used to build an SMPP client that can make SMPP requests using Java. This library's higher-level functions can be used to synchronously submit SMS to an SMS gateway or SMSC.

SMPP requirements and resources

SMPP is the Short Message Peer-to-Peer protocol and is used by applications for sending and receiving SMS. An SMPP client can be used to connect to an SMSC or SMS gateway using the SMPP protocol. An SMPP account, including special Developer accounts, can quickly and easily be obtained for using the Melrose Labs Tyr SMS Gateway or SMSC Simulator. The following are required to send SMS with SMPP:

• SMPP API account
  SMPP API account for the Melrose Labs Tyr SMS Gateway.
• SMSC Simulator
  SMPP API account for simulating inbound and outbound SMS delivery.
• SMPP Protocol [reference]
  Short Message Peer-to-Peer Protocol v3.3, v3.4 and v5 specifications and guides
• SMPP v5 [reference]
  Short Message Peer-to-Peer Protocol v5 reference on melroselabs.com

Java requirements and resources

Java is a programming language and can be used to quickly and easily add SMS support for programmatically sending and receiving SMS messages. Use it for transactional messaging and notifications between your application and mobiles. The following are required to send SMS using Java:

• Java
  Java programming language

Requirements and resources

The following are required to send SMS with SMPP using Java:

• jSMPP
  jSMPP Java Library

Code

Create the file SimpleSubmitExample.java containing the code below. Replace the hostname smscsim.melroselabs.com, port 2775, SYSTEMID and PASSWORD values with those from your SMPP API account. Alternatively, replace SYSTEMID and PASSWORD with those allocated to you for use with the Melrose Labs SMSC Simulator.

The following example Java code opens an SMPP transmitter bind to smscsim.melroselabs.com on port 2775 (SMPP port), and then sends the message Hello World #$£ to mobile number 447712345678 from MelroseLabs. The message ID returned in messageId is that returned from the SMS gateway or SMSC after a successful submission. The SMPP system ID and password for the SMPP account are contained in SYSTEMID and PASSWORD respectively.

Using in production

Whatever the language or API, you can send SMS and receive SMS between applications and mobiles for a wide range of uses with any of the trusted and reliable CPaaS services from Melrose Labs. Take a look at our Messaging, SMS gateway and Bulk SMS solutions, and sign-up for a Developer account on our Tyr SMS Gateway service to try us out.

We provide a wide range of CPaaS services and infrastructure to organisations, including cloud platforms that enable you to run your own SMS gateway.

Get in contact with us to find out more about CPaaS voice, messaging, video and identity from Melrose Labs.

Testing

For testing your application's SMS support when using the SMPP protocol, we recommend starting with the Melrose Labs SMSC Simulator service to simulate SMS message delivery to mobiles (MT SMS) and simulate SMS messages from mobiles (MO SMS). The SMSC Simulator supports SMPP v3.3, v3.4 and v5.

For live testing and delivery to mobiles, use the reliable and dependable Melrose Labs Tyr SMS Gateway for A2P, P2A, bulk, wholesale and business SMS, text marketing and other uses. The Melrose Labs Tyr SMS Gateway supports REST and SMPP APIs.
