Krimston Two, an innovative accessory for the Apple iPhone, enables users to work two SIM cards simultaneously. The device, which looks like a slick protective case for your phone, contains an additional SIM card. It allows the user to have two lines active at the same time, controlled by the main phone’s display.
The gadget is the answer to many a traveller’s prayers as it is the perfect way to avoid roaming fees. It’s also a great fit for people who use a different phone for work and personal calls.
