Norway

Basics
Norway has three networks, run by two companies: Telenor is still market leader closely followed by Telia that has taken over third-ranked Tele2 in 2015. Tele2 is now merged with Telia or roams on their network in 2-4G through national network sharing. 2G is on 900 and 1800 MHz, 3G on 900 and 2100 MHz and 4G/LTE started on 800, 1800 and 2600 MHz on all operators.
 * Telenor
 * Telia (formerly NetCom) merged with Tele2 (by Network Norway, acquired by Telia)

Another provider sold under the brand of ice.net run by Access Industries offers mobile broadband based on LTE on 450, 800 and 1800 MHz with a pretty large footprint all over the country. But it's limited to contract subscribers and not offered for prepaid. So it's not mentioned any further.

Regulations
Although Norway is not part of the EU, but of the European Economic Area (EEA), and as such roaming rates are regulated like all over the EU. Foreigners have to buy the starter pack in a shop showing their photo ID for registration. The operators and most of the MVNOs are geared to contract customers, so there is only a rather limited choice of prepaid SIM cards, which are locally called Kontantkort.

Coverage
Many public places and public transport are covered by WiFi. For instance, the shuttle bus from Oslo airport to downtown has free WiFi. Norwegian airline provides free WiFi, many ferries and metro trains as well. So you might not need mobile internet rightaway. Populated areas have good mobile coverage, except some remote mountains or fjords. The Svalbard archipelago (including its main island Spitsbergen) is covered by all Norwegian providers as well.

Telenor
Telenor is market leader in Norway with more than 50% of the national users on its network. It has a good coverage and speeds throughout the country: Telenor Coverage map. 4G/LTE is available for prepaid, but max. speed is 6 Mbit/s.

Availability
Their prepaid SIM is called Telenor Kontant. It's sold at Telenor shops (store locator), many convenience stores like Narvesen, 7-Eleven, Deli de Luca, Mix and electronic retailers for 200 NOK (including 50 NOK credit).

For travelers entering through Oslo Gardermoen Aiport (OSL), there is a cellphone retailer (shop sign: "Mobiles") in the main terminal, next to the rental car counter. Travellers need to provide their passports and the address of your country and Norway (hotel). Many shop attendants in convenience stores won't do the registration. Instead, better drop by the mobile or electronic dedicated stores or a Telenor store to purchase the SIM card. Mini/micro/nano SIM cards are available for 200 NOK start-up with 50 NOK credit. Mini SIM card is pre-cut into micro/nano size.

Account management and recharging
To check your account balance, send SMS with text SALDO to number 2525. You can also call the service number 91500500 (Norwegian only).

You can try recharging using EU-issued credit card on Telenor website, but it accepts mainly Scandinavian credit cards.

Instead, vouchers can be bought at any convenience store in the country. Additional credit can be topped up with the minimum of 200 NOK. The vouchers are in Norwegian language only but the top-up menu can be switched to English. If you buy the credits at places like 7-Eleven, they will print out a "Ladekode" (top-up code) with instructions in Norwegian. You can follow instructions (ask the cashier of 7-Eleven if you can't read Norwegian, but it's not their duty to help you). You can top-up credit by the calling phone given in the instruction. But this phone line doesn't have an English menu, so you might need another help from the staff. You enter the "Ladekode" and that's it. You might need to reboot the phone to update carrier database. if you use an iPhone.

Default data rate
The SIM card has a flat rate of max. 10 NOK per day for data. If you use more you won't get billed more than 10 NOK, but speed is reduced to 128 Kbps, when you exceed 500 MB downloaded data per month.

These data packages called Datapakker are available for the Kontantkort, but all of them are very longterm running: Shorter packages are not available. Activation is texting name to 1999.
