Tyr SMS Gateway

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

Melrose Labs launches its mobile messaging services in days hours
Tyr SMS Gateway

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.

Bulk SMS Accounts

A2P (application-to-person) bulk SMS messaging is the sending of large numbers of SMS messages for delivery to mobiles. A2P bulk SMS accounts provide access to an SMSC gateway for sending SMS, the capacity to handle high volumes of SMS messages and wholesale SMS pricing.

The Tyr SMS Gateway is suitable for bulk SMS, i.e. high volumes of SMS messages, as well as low volume messaging. 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.

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.


A2P SMS for IoT/M2M, OTP, marketing and notifications to customers and staff.


Can be depended upon 24x7 for your business to send and receive SMS.


Advanced infrastructure with mulitple APIs for customers to use.


Coverage includes almost every mobile network in the world (>1000 networks).


Tyr SMS Gateway Upcoming Services

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 the following HTTP REST SMS API:

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


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"}

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

    "x-api-key: [API_KEY]",
    "Content-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.


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.

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 >

Tyr (pronounced like the English word “tier”; Old Norse Týr) is a Norse war god, but also the god who, more than any other, presides over matters of law and justice.
