Carrying two phones at a time may be cumbersome for some who have different numbers for personal and business use . But now you can use Dual Sim Cards on your iPhone 4 just by switching to the 2nd sim on the external sim tray. Its pretty easy with this dual sim accessory available for iPhone 4 (picture below). The case is similar to the dual sim iphone 4 adapter case we have covered before .
How it Works :
A sim like connector enters in the default micro sim slot and extends outside the body of the iphone 4 . This outer piece is capable of holding two sim cards . This is now folded inside the case . Only one sim can work at a time .
