I use the little key (looks like a paperclip) that came with the iPhone to do it. Basically, all you have to do is put the end of the key (or paperclip) into the little hole and push firmly. The SIM door should pop out a little letting you pull it out with your fingers. Facebook: http://www.facebook.com/phonebuff.
Currency of Srilanka. Currency of Sri Lanka is Sri Lankan Rupee. One Sri Lankan Rupee consists of 100 cents. Coins come in the denomination 5, 10, 25 and 50 cents and Rs. 1, 2, 5 and 10. The higher value denominations are found as notes, namely Rs.10, 20, 50, 100, 200, 500 and 1000.
Sri Lanka decimalised its rupee in 1869. The Indian Coinage Act was amended in September 1955 for the adoption of a decimal system for coinage. The Act came into force with effect from 1 April 1957. The rupee remained unchanged in value and nomenclature. It, however, was now divided into 100 'Paisa' instead of 16 Annas or 64 Pice.
