With the iPhone 4 microsim being smaller in size, it seems incapable of fitting earlier models, making it difficult to swap services. The MicroSim Shop makes available the Micro-Sim adapter which enables users to fit in their iPhone 4 or iPad 3G SIM into a plastic shell that helps users to employ it in the iPhone 3G and iPhone 3GS.
The iPhone 4 has the MicroSim located in a slot on the right side of the device that enables users to take their iPhone 4 microSIM and use it in another SIM-unlocked handset. Users usually face problems when they break the wrong SIM card size out of the ID-1 SIM card. Apple iPad and iPhone SIMs are generally not compatible as the iPad has a Mini-UICC-SIM and the iPhone has a normal SIM. All these challenges seem to have pushed for the need of an adapter that can bring two generations of mobile phones and SIMs together.
The adapter allows use of one SIM card for all devices. It is compatible with all generation 3 SIM cards and can be used in Micro-SIM, 3ff and Mini-UICC. Users can now use the same SIM on the iPad and the iphone.
MicroSim Shop provides the MicroSIM Adapter for a price of € 5.99 for a limited period.
