Interface information

tyntec’s Inter-Carrier Messaging Service (ICMS) MM4 interface is a service that enables you to exchange MMS with all operators listed on tyntec’s reach list by using the MM4 protocol. MM4 is based on the Simple Mail Transfer Protocol (SMTP), a standard e-mail protocol.

A VPN is established between tyntec and the customer, providing a secure link between the two parties.

The following illustrates an example of the workflow for sending/receiving MMS:

Outbound MMS

Inbound MMS

Send an MMS message from your own system to the tyntec platform. The message will be delivered to the subscriber through the operator network.

Receive an MMS message from the subscriber, through the tyntec platform connected to the operator network.
