Posted on July 7, 2011 by Clyde Thorburn
All owners and users of US sim phone cards bought from HolidayPhone need to understand the origins, history and technical specifications of the sim card, which has now developed into the prepaid sim card of which people can purchase US prepaid sim cards in the united Kingdom before they embark on their respective journeys to the United States of America. Wikipedia, the free encyclopaedia on the internet, defines a sim card as, quote “A subscriber identity module or subscriber identification module (SIM) is an integrated circuit that securely stores the service subscriber key (IMSI) used to identify a subscriber on mobile telephony devices such as mobile phones and computers” end quote.
Owners of a prepaid USA sim card will be interested to know that ‘A SIM’ is a circuit that has been embedded on a removable sim card and that sim card or prepaid sim card can be used in many different types of mobile phones. When sim cards, including the existing prepaid US sim card, were first manufactured, they were all made the same size as a standard credit card. This standard size was eighty five point six millimetres long, fifty three point nine eight millimetres wide and zero point seven six millimetres thick. Due to mobile phones becoming and being manufactured in smaller and smaller sizes the manufacture of the sim cards, as well as US sim phone cards had to keep pace with the small mobile phones and the smaller prepaid sim card or mini sim card was the result.
People who have purchased US sim phone cards from HolidayPhone will find it interesting that mini sim cards are the same thickness as the standard credit card that is used worldwide. This thickness, again, is zero point seven six millimetres. Obviously the length and width of the mini sim card is a lot less than the standard eighty five point six millimetres long and fifty three point nine eight millimetres wide of the standard sim card and have been made with the smaller dimensions of only twenty five millimetres long and fifteen millimetres wide. So, to summarise, there are two sizes of prepaid sim cards. The one being the standard size as detailed above and the other type of prepaid sim card is known and referred to as the mini sim card which is much smaller in size.
