Customers across the country affected

The bug has also affected some customers abroad.

Telenor has appointed a crisis task force after the country's largest digital services provider experienced issues with its mobile network on the Whitsun evening.

On Sunday morning, the glitch was fixed and traffic returned to normal since late Saturday. This is what Telenor's press director, Anders Krokan, says.

– He says that the reason for the instability experienced by some customers was due to a fault in one of the components of the central hub in our network.

Crokan says Telenor is now reviewing the course of events, and closely monitoring the network to ensure stability.

If you're still having trouble getting coverage, Crokan recommends restarting the router, or setting your mobile phone to airplane mode and back.

“It might be a good idea to do this regardless of whether you've had any problems or not, to be sure,” Crocan says.

– What to do if it doesn't help then?

– It should work.

Telenor customer service does not open until 08:00 on Tuesday. Several people have contacted VG regarding this matter.

– Have you thought about setting up customer service due to the error?

“Traffic is now low for our customer service, and we have included information for those who contact us about the error,” says Crokan.

– As things stand now, we are not putting additional resources into customer service.

– Normalization

By Saturday evening, the situation was stabilizing.

– Telenor has implemented measures to normalize the situation. We are still working to ensure complete stability, and are closely monitoring traffic. We apologize to all customers affected by the error situation, Telenor's press director, Anders Krokan, wrote in a message to VG late Saturday evening.

It was reported earlier that instability in the mobile network caused some calls to fail and mobile data was down for some.

-If some customers do not get a backup of all services, we recommend that they put the mobile phone in airplane mode, then turn it on again.

– What we see is that it is somewhat sporadic, but in different regions of the country. Crocan said earlier in the evening that it was too early to say anything about the number of people affected. He then emphasized that only “some” had problems.

VG received several tips on Saturday evening about a problem with Telenor. The tips relate to several parts of the country. Some also write that there is a problem with the mobile network abroad. Crocan confirms this shortly before 11.30pm.

VG has also been informed that payment terminals, self-service store openings and electric scooters have been suspended.

At 21.15, Telenor's coverage manager, Björn Amundsen, reported Bergens Tidendi Telenor has appointed a crisis team.

-We always do that with these kind of events. He says the technical department is now working on troubleshooting.

Home service is affected by Telenor problems. At Osteridet Hospital in Alvear, they do not receive alerts from patients.

– It is dangerous for patients and very stressful. So far, things have gone well, fortunately. We have to visit patients often to check if they need anything, employee Ann-Kitty Bertheussen tells VG.

Krokan at Telenor says there are no indications that Telenor is vulnerable to hacking.

– We are working in full swing to restore the stability of the mobile phone network again, and solve the problems we face. We have had violations since 8 p.m.

Telenor's problems also create problems for ambulances in Oslo.

Oslo University Hospital's press officer, Anders Baer, ​​told VG that they have lost GPS tags and are not allowed to send assignments to specific ambulances.

– But we compensate well for this with good communication via voice, emergency network and mobile network. Thus, we have no recorded delays in ambulance missions due to Telenor issues, says Bayer.
