The country code for Finland is 358. You must begin all direct overseas calls with 990, 996, 999, or 00, plus country code (e.g., 1 for the United States and Canada). If you're dialing out of your immediate area within Finland, dial 0 first; drop the 0 when calling Finland from abroad.
Dial020–208 for overseas information or to place collect calls. Dial 118 or 020202 for information in Helsinki and elsewhere in Finland; 020208 for international information (€3.49 per minute plus local charge).
Major urban areas in Finland have moved to a phone-card system, and most phones only accept cards (no coins), which fortunately are usually available nearby at post offices, R-kiosks, and some grocery stores. Public phones charge a minimum of about €0.50. Most pay phones have picture instructions illustrating how they operate. Note that regional phone companies have their own cards that don't work in telephones in other regions. The main companies include Sonera, Elisa (Helsinki), and Soon Communications (Tampere).
Finland, like most European countries, has a different cellular-phone switching system from the one used in North America. Newer phones can handle both technologies; check with the dealer where you purchased your phone to see if it can work on the European system, in which case you can rent prepaid SIM cards from R-Kiosks throughout the country. Telephone companies including Sonera and DNA rent and sell old phones.
