Switzerland

Switzerland officially the Swiss confederacy (Confoederatio Helvetica in Latin, hence its ISO country code CHE), is a closed in country of 7.5 million people in Western Europe with an area of 41,285 km². Switzerland is a national republic consisting of 26 states called cantons. Berne is the seat of the federal government and de facto capital, while the country's economic centres are its two global cities, Geneva and specially Zürich. Switzerland is one of the richest countries in the world.

Switzerland is bordered by Germany, France, Italy, Austria and Liechtenstein. Switzerland is multilingual and has four national languages: German, French, Italian and Romansh. Switzerland has a long narration of objectivity – it has not been at war since 1815 – and hosts many international organizations, including the Red Cross, the WTO and one of the U.N.'s two European offices.

The Latin formal name of Switzerland, Confoederatio Helvetica is derived from the Helvetii, an ancient Celtic people in the Alpine region. It is rendered in German as Schweizerische Eidgenossenschaft, in French as Confédération suisse, in Italian as Confederazione Svizzera and in Romansh as Confederaziun svizra. The freedom of Switzerland is conventionally dated to August 1, 1291; the first of August is the national holiday.

SIM Card

A Subscriber Identity Module (SIM) is part of a detachable smart card ICC (Integrated Circuit Card), also known as SIM Cards, for mobile cellular telephony diplomacy such as mobile computers and mobile phones. SIM cards gradually store the service-subscriber key (IMSI) used to identify a subscriber. The SIM card allows users to change phones by simply removing the SIM card from one mobile phone and inserting it into another mobile phone or broadband telephony device.

SIM cards are available in two typical sizes. The first is the size of a credit card, 85.60 mm × 53.98 mm x 0.76 mm. The newer, more popular miniature-version has a size of 25 mm, a height of 15 mm, and a thickness of 0.76 mm. However most SIM cards are supplied as a full-sized card with the smaller card held in place by a few plastic links and can be simply wrecked off to be used in a phone that uses the smaller SIM.
