Around 800,000 mobile phone users across Norway were hit after Tele2 suffered network problems on Sunday.
The problem, which started at 10pm, also affected customers of One Call, Network Norway and MyCall, and involved phone users having technical disruptions when making calls, using the internet and sending text messages.
Tele2 announced via Twitter on Sunday: “Customers may experience loss of signal. We are working very hard to correct the error and will update when we know more.”
The telecoms company did fix the problem by a few hours later by midnight on Sunday and announced customers could use their services as normal. The problem was confirmed as originating from a server in Oslo.
Hanne Løvstad, press officer for Tele2, said to NRK: ”It seems like only outgoing calls were affected. We apologize for any inconvenience this created for our customers.”
Another Norwegian network, Telenor, encountered disruption at the weekend after several base stations had technical problems due to adverse weather in Norway.
Atle Lessum, press officer at Telenor, said: “We have had several base stations out of order because of the bad weather this weekend. In total Telenor had more than 100 base stations out of order. It is uncertain how many customers this will affect.”
