Telness Tech renamed itself Valdyr on 15 September 2026. Changed from the brief’s table: it does not claim the MVNE role (it sells to MVNEs and partners with MVNAs) nor sell connectivity (it integrates operators and aggregators), so only MVNO Software Provider stands. The Telness operator brand now belongs to Telia.
