The international dialing code for Sweden is +46. Payphones are available (albeit very uncommon), with older versions only taking cards (special smartchip phone cards as well as credit cards) and never accepting coins (Swedish as well as Euros). Collect calls may be made by dialing 2# from a pay phone.
Except in the country’s center and northern core, Sweden has good wireless GSM and 3G/UMTS coverage, especially in remote regions. Telia, Tele2/Comviq, Telenor, and 3 are the main networks (Tre). Swedish GSM uses the European 900/1800 MHz frequencies (Americans would require a triband phone), whereas 3G/UMTS uses the 2100 MHz frequencies (currently with 7.2–14.4 Mbit HSDPA speeds). Telia’s network is the only one that supports EDGE. Some operators may need a Swedish personnummer (or samordningsnummer) to get a number, however most operators provide prepaid without requiring a “personnummer” or ID, and these are available and refilled at most supermarkets and cigarette shops. If the term “prepaid” is not understood, request a Kontant Kort.
Prepaid USB 3G modems are available in a variety of stores. In Sweden, they are a viable alternative to WiFi. They cost around 100 SEK per week and 300 SEK per month to use. Data caps are high (usually 20 GB per month). The number of WiFi access sites is increasing, and fast food restaurants, libraries, motels, cafés, and shopping malls, among others, may provide free wireless internet access. There are also fixed terminals where you may pay for internet access, but many libraries can offer the same service for free.
The prepaid 3G data plan purchased in Sweden by provider 3 may be used in Denmark without incurring any roaming charges. Refill coupons for these items, however, are not available in Danish shops.
Tethering is supported by COMVIQ, making it simple to connect more than one device to the internet if you bring along an old smart phone or dual SIM mobile.
Sweden is the world’s second-most-connected nation to the Internet (second to Iceland). The Swedish postal system (PostNord or just Posten) is often regarded as efficient and dependable, with franchisees located in supermarkets and convenience shops (look for the yellow horn logo). Ordinary letters (to anyone in the world) cost 14 SEK in stamps, and the mail typically takes 2 days inside the EU. Stamps are available at most supermarkets; just ask the clerk.
