SIMs are also able to store address book contacts information, and may be protected using a PIN code to prevent unauthorized use. SIMs are always used on GSM phones; for CDMA phones, they are needed only for LTE-capable handsets. SIM cards are also used in various satellite phones, smart watches, computers, or cameras. The first SIM cards were the size of credit and bank cards; sizes were reduced several times over the years, usually keeping electrical contacts the same, to fit smaller-sized devices. SIMs are transferable between different mobile devices by removing the card itself. Technically, the actual physic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
