How it works
Technology behind the solution
- Initially, all SMS messages sent or received by roaming operators are routed through the SS7 network. There is therefore an end-to-end exchange based on the same technology.
- Decommissioning 2G/3G core networks creates a technological gap between operators, disrupting the connection and obstructing the traffic flow.
- The Interworking solution we have implemented restores the link between you and your roaming partners by translating the message transparently.
- On one side, your roaming partner continues to use the SS7 protocol, and on the other, you rely on the LTE SGd protocol.
- For a better experience, we recommend using your GT (Global Title) range, allowing us to manage the traffic in a more flexible or centralized way.

FAQ
Answers to your frequently asked questions.
To ensure SMS compatibility while roaming after the sunset, an interworking solution must be deployed to translate messages between the SS7 (2G/3G) and LTE (4G) protocols. This gateway ensures the continuity of SMS exchanges in accordance with GSMA standards. It is also important to collaborate with partners, update the infrastructure, and follow recommended best practices to ensure a smooth transition.
The SMS interworking solution enables the translation of SMS messages between the SS7 protocol (used in 2G/3G) and the LTE protocol (4G), thereby ensuring the continuity of SMS services while roaming, even when certain networks are down. It is essential for preventing service interruptions and maintaining a seamless user experience.
