Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A Dual SIM mobile phone is one which holds two SIM cards. Initially, dual-SIM adapters were made available to use in regular mobile phones to allow them to contain two SIMs, and to switch from one to the other as required. This combination is called a standby dual-SIM phone. The first Dual SIM mobile phone was Benefon Twin manufactured by Benefon in Finland. It was launched on the market in 2000. More recently, some phones have been produced that can natively work with two SIMs, both of which may be active at the same time. These are active dual-SIM phones. There are also some Chinese triple-SIM phones.show more
