This small device allows you to run two SIM cards in one mobile phone at the same time. With this new version you do not need to hack up your SIM cards to make them fit. It appears that one SIM card goes over the battery and the other one in the regular place. It will not work with USIM 3G cards, but will work with a good number of other handsets. This version also does not require you to switch off the mobile phoneto change numbers. You have an option on screen to switch between SIM1 and SIM2. For full details check outGr8 Idea .
