Data migration and exports, we handle all of it – best in the business.
We do it for you, using proven migration and strategies. It’s done in weeks, not months, and we support migration across networks and markets, including brownfields between segments and verticals. We optimize as we migrate - launching new features or markets as needed. One example: 11 brands migrated and launched in less than 6 weeks.
Don’t just migrate - upgrade while you’re at it.
Use migration as an opportunity to do more than just move.
Reduce OPEX through built-in automation, remove manual work and overhead, and retire your legacy IT stack by consolidating everything into one platform. You can even add new features or launch new markets during the migration.
If you want to do something, do it yourself - our self-service platform empowers your team to run all tech operations without needing external admins.
Seamless OS makes operations leaner, more powerful, and more scalable. The result? The highest customer ratings in the industry.
Do more with less. Simplify, automate and still enhance your capabilities.
It's 2025 — move your entire telco operation into one place: billing, dashboards, campaigns, products, marketing, and support — all fully branded.
Maximise customer happiness with a cohesive, elegant user experience, instead of forcing them to use multiple disconnected systems.
And yes — your staff will love it too.
Built for developers.
Let’s not mince words: Telness Tech and Seamless OS offer the most powerful and configurable BSS/OSS in the industry. Built from the ground up to be modular and open, Seamless can integrate with any product, service, or architecture you already have. We support your devs with open APIs, detailed guidelines and tutorials, constantly updated docs, real-world example flows, and first-line developer support if needed.
That’s why we call it Seamless.
Lowest churn in all of telco.
Some of our clients run international MVNOs with teams of just seven people. Thanks to automation and self-service, they operate lean while delivering premium customer experiences.
The result? 4.8 Trustpilot rating and the lowest churn rate in the industry.
Self-service + full automation = customer satisfaction + profitability.
