Hiya's Call Protection Technology Powers Telenor Sweden's New Nummerkoll Service

SEATTLE, May 28, 2026 – Hiya, the global leader in AI-powered voice security and identity, announced that Telenor Sweden has deployed Hiya Protect across its consumer mobile network, delivering real-time call protection to Swedish subscribers. The service, branded locally as Nummerkoll, automatically identifies and labels suspicious incoming calls at the network level, requiring no app download or setup from subscribers.

Nummerkoll is available as part of Telenor Sweden's new mobile portfolio, with plans for continued expansion. The service is enabled automatically at the network level, and subscribers retain full control over whether to answer flagged calls or can opt out of the service entirely.

Spam and fraud calls are a growing crisis for European mobile subscribers. Hiya’s 2026 State of the Call report, a survey of more than 12,000 consumers in six countries, uncovered that 62% believe phone spam has gotten worse over the past year. The threat is evolving, with one in three reporting they received an AI deepfake voice call in the past twelve months. The pressure on operators is real, with almost 40% of consumers saying they have considered switching providers over inadequate spam and fraud protection.

Hiya Protect operates directly within the operator network, evaluating incoming calls in real time. Subscribers benefit by seeing clear on-device labels such as ‘Potential Fraud’ before deciding whether to answer a call.

“The operators that are winning right now are the ones that treat call protection as a core part of their service, not an afterthought. Telenor Sweden is making that commitment to every subscriber on their network, and that is exactly the kind of leadership this industry needs.”

The Telenor Sweden launch marks the latest in a series of major European operator deployments for Hiya, following launches with Telenor Norway, DNA Finland, Deutsche Telekom, Vodafone, and O2 Telefónica.
