Tyr SMS Gateway

SMS service for transactional and bulk SMS. SMPP and REST SMS APIs supported.

Global, highly reliable and technically rich SMS gateway to send and receive SMS between applications and mobiles. Send and receive SMS using our webSMS portal and SMS APIs that include SMPP (v3.3, v3.4, v5 supported), SMTP (emailSMS: email-to-SMS and SMS-to-email), and secure HTTP REST. Coverage highlights of the Tyr SMS Gateway include UK, France, Germany, Spain and Italy.

Tyr SMS Gateway accounts can be used for sending messages to mobiles on almost any mobile network in the world. Accounts can also be used for P2A (person-to-application) SMS to receive inbound SMS from many mobile networks around the world, using Virtual Mobile Numbers (VMNs) or SIM Hosting.




Developer accounts provide easy access to the Tyr SMS Gateway for sending and receiving SMS. Use either the REST API or SMPP for messages.

Accounts are restricted to 5 nominated mobile numbers.

Pricing is super cheap to help you get your application or integration built.


Enterprise accounts provide access to the Tyr SMS Gateway for reliably sending and receiving SMS. Enterprise accounts can handle high volumes of outbound and inbound SMS messages, with over 1000 networks worldwide able to be sent SMS.

High rates of SMS traffic can be handled using SMPP, REST API, webSMS or emailSMS.

Pricing is based on the volume of messages sent and received.

Bulk SMS

A2P bulk SMS accounts provide access to the Tyr SMS Gateway for sending SMS, the capacity to handle high volumes of SMS messages and extremely competitive wholesale SMS pricing.

Accounts are capable of handling up to 2000 SMS/sec on request with single or multiple SMPP gateway binds. We recommend SMPP rather than REST for bulk SMS.

Pricing is our buy-in cost (i.e. 0% mark-up), and we charge a fixed service fee or minimum invoice amount.

Reliable and Dependable SMS

Highly redundant and available messaging infrastructure.

Our services can be depended upon to deliver your messages 24x7. The Tyr SMS Gateway infrastructure that we operate for message delivery spans multiple redundant, independent and geographically separate sites throughout Europe, Asia and the Americas.

In the unlikely event that one of our sites completely fails, our remaining sites will continue to provide service for all of our SMS APIs. The redundancy includes both inbound and outbound SMS.

Two-Way SMS and Receiving SMS from mobiles

Enable applications to receive SMS from mobile users for marketing campaigns, receiving SMS from mobile devices for IoT/M2M, and other uses. Use with sending SMS to mobiles to enable two-way SMS messaging.

Virtual SIM Hosting

Virtual SIM Hosting (VSIM) provides a high performance method of receiving up to 200 SMS per second through a customer-supplied SIM. The mobile number of the SIM can be used to receive SMS without the restrictions of normal SIM card hosting. This service is a means of getting the performance of Virtual Mobile Numbers (VMNs) with the advantage of a national mobile number (e.g. a SIM from a mobile network in France for use with a service targeted at mobile users in France).

Virtual Mobile Numbers

Virtual Mobile Numbers (VMNs) bring high performance with low delivery latency of messages from mobiles to applications. A single Virtual Mobile Number allows an application to receive incoming SMS from all supported networks worldwide. The Virtual Mobile Numbers behave in the same way as a regular mobile number, but with the benefit of significantly higher throughput (200 SMS per second) to your application.

The Tyr SMS Gateway has the capacity and technical capability to be used for sending high volumes of SMS messaging quickly and reliably to mobile users in a single country or worldwide. The SMPP API is well-suited to this use; however, we also provide our HTTP REST SMS API (HTTP-to-SMS) that can be equally suitable or our SMTP API (email to SMS / SMS to email / SMTP to SMS) if you prefer. Using these APIs, messages can be sent from your application or systems through your Tyr SMS Gateway account and delivered within seconds. Delivery receipts are also provided in realtime to indicate the delivery status of your messages.

Tutorials for how to programmatically send SMS can be found at the following:


The Melrose Labs Tyr SMS Gateway service is available using our REST SMS API.

Send an SMS message with the RESTful HTTP SMS API
Example using cURL, Node.js, Python, PHP


curl --location --request POST https://api.melroselabs.com/sms/message/ \
	--header 'x-api-key: [API_KEY]' --header 'Content-Type: application/json' \
	--data-raw '{ "source": "MelroseLabs","destination": "447712345678","message": "Hello World €£$" }'


{"transactionID": "1ccead78-6550-4aac-a6b4-a4942b908659"}


var request = require('request');
var options = {
  'method': 'POST',
  'url': 'https://api.melroselabs.com/sms/message/',
  'headers': {
    'x-api-key': '[API_KEY]',
    'Content-Type': 'application/json'
  body: JSON.stringify({ "source": "MelroseLabs","destination": "447712345678","message": "Hello World €£$" })
request(options, function (error, response) { 
  if (error) throw new Error(error);
  console.log(response.body); // response is of type application/json


{"transactionID": "1ccead78-6550-4aac-a6b4-a4942b908659"}


import requests

headers = {
  'x-api-key': '[API_KEY]',
  'Content-Type': 'application/json'

response = requests.request("POST", url, headers=headers, data = json.dumps(payload))

# response is of type application/json


{"transactionID": "1ccead78-6550-4aac-a6b4-a4942b908659"}


$data = { "source": "MelroseLabs","destination": "447712345678","message": "Hello World €£$" }

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://api.melroselabs.com/sms/message/",
    "x-api-key: [API_KEY]",
    "Content-Type: application/json"

$response = curl_exec($curl);


echo $response; // response is of type application/json

SMS Webhook Support

When an inbound MO SMS is received from a mobile, or a delivery receipt is generated for an MT SMS to a mobile, a call can be made to your webhook to convey the event.

Get your API Key now and start using the Tyr SMS Gateway service REST API



Use Short Message Peer-to-Peer (SMPP) to send SMS to mobiles with the highest level of control, and is suitable for low or high volumes of SMS. SMPP versions 3.3, 3.4 and 5 are supported, and TLS can be used to secure the session between your application and the Tyr SMS Gateway. We believe that for both MO and MT SMS our SMPP API of the Tyr SMS Gateway service is the most reliable, available and capable implementation available from any SMPP provider.

Our SMPP v5 reference is available to provide details on our implementation of SMPP. It is also relevant for v3.4, and to a lesser degree v3.3.

Data Retention and Data Privacy

Data retention and data privacy policies ensure that data is handled securely and in accordance with GDPR. Mobile telephone numbers and message content are kept encrypted at rest and in motion whenever possible. Account-level policies ensure that messages are erased in line with your organisation's data retention policy.

SMSC Simulator

Looking to test your SMS application or SMS-enabled application before connecting to a live SMS gateway or SMSC? Our SMSC Simulator service allows you to test using the SMPP protocol v3.3, v3.4 and v5. Read more about SMSC Simulator >
