Our work in the telecom sector
Connecting telecom logistics across the Nordics and Baltics
Helmes developed COLT, Telia’s logistics management platform used across five countries. Continuously evolved for more than a decade, it streamlines supply chain operations, supports e-commerce growth, and improves visibility across sales channels and warehouses.
- 4M+ orders annually
- 300M+ interactions with other systems annually
Network intelligence & service assurance
Since 2013, Helmes has partnered with VIAVI Solutions to build network data management and location intelligence platforms. The solutions help telecom operators analyse performance, detect issues faster, and optimise networks using real-world and geospatial data.
- 150 million events processed per minute
- 50+ operators using VIAVI NITRO Location Intelligence
One after-sales platform across six countries
Helmes developed a shared platform for managing device repairs, returns and repurchases across Telia’s operations. The system connects customer service, self-service channels and external partners, supporting more efficient processes and device reuse.
- 400+ stores across 6 countries
- 100+ system integrations
eSIM connectivity across devices
Helmes developed a central eSIM integration platform and device-native services, connecting telecom operators, eSIM vendors and digital sales channels. The work includes GSMA-standard integrations and connectivity solutions for smartphones, smartwatches and laptops.
