GSM is the most widely used system. Two service providers cover 80 percent of the populated areas. They are:
Tel: + 47 22 785000
Fax: + 47 22 785500
Tel: + 47 22 888200
Fax: + 47 22 888050
An alternative option to buying a cell phone abroad is to use an international cell phone with a prepaid Norway SIM card. All incoming calls while you travel in Norway are FREE, regardless of where they originate. The Norway SIM card provides service across Norway through domestic roaming.

Another option is the pay-as-you-go mobile phone. These can be purchased at supermarkets, gas stations, news stands, and phone kiosks. They may also be purchased online which usually offers the best price.
