Coverage and network

Coverage city, fjord and mountain

Norway mobile networks

Norway ranks 22nd worldwide at about 156 Mbps and Oslo measures around 258. Telenor's reach into the countryside is better than the terrain has any right to allow. The fjords and the high country are still the fjords and the high country.

Oslo and Norway, specifically

  • Central Oslo, Grünerløkka, Aker Brygge: Fast 5G. The city is compact and well covered.
  • The T-bane and the Holmenkollen line: Covered, including the tunnels. The line up to Holmenkollen and Frognerseteren keeps signal, which is the easiest way to get into the forest from the city.
  • Nordmarka and the marka forest: The trails immediately behind Oslo are surprisingly well covered - Norwegians use them constantly. The deeper you go the patchier it gets.
  • The Bergen railway and the fjords: The train holds signal for much of the crossing with long tunnel gaps through the mountains. In the fjords proper, coverage follows the settlements: Flåm and Geiranger are fine, the walls between them are not.
  • Winter and the far north: Above the Arctic Circle coverage tracks the roads and towns. In the cold a phone battery drains fast, and if you are chasing the aurora you will be standing outside in it for hours - keep it warm and take a power bank.

Norway, and the EEA

The plan covers all of Norway. Norway is not an EU member but is in the EEA, and EU roaming rules extend to the EEA - so the same terms carry into Sweden, Denmark and the EU proper.

Arriving in Oslo

Airport Wi-Fi at Gardermoen

Oslo Gardermoen has free terminal Wi-Fi. The Flytoget express reaches the city in about 20 minutes, and Norway is expensive enough that checking whether the cheaper regional train suits you is worth doing before you buy a ticket.

Free terminal Wi-Fi - Flytoget express to the centre in about 20 minutes
Torp (TRF) and Rygge
Low-cost airports well outside the city - long bus transfers

Frequently asked questions

Coverage

Norway is not in the EU - does EU roaming apply?

Yes, and this trips people up in both directions. Norway is outside the European Union but inside the European Economic Area, and the roam-like-at-home rules extend to the EEA - so Norway, Iceland and Liechtenstein are treated like EU countries for roaming, while Switzerland and Monaco are not. A plan covering Norway carries into Sweden and the EU on the same terms.

Where to buy a SIM card in Oslo?

Telenor and Telia have shops in the centre, and Narvesen kiosks sell prepaid. Norway requires registration against an identity document. It is quick, but Norwegian prices are what they are - a prepaid bundle here costs noticeably more than the same thing in Poland.

Is there coverage in the fjords?

In the villages and along the main roads and rail lines, yes - better than the terrain suggests, because Telenor has invested heavily in rural reach. Between settlements, in the tunnels and up on the plateaus, no. The Bergen railway spends a lot of its journey inside mountains.

Troubleshooting

eSIM not working in Oslo?

In the fjord tunnels or up on a plateau, a gap is the terrain. In winter, check the phone has not gone flat in the cold. Otherwise select Ohayu for mobile data, allow roaming, then cycle Airplane mode. Chat and support@ohayu.com are open 24/7.
