Twin SIM-card holders enable you to use two different SIM cards with two different phone numbers i.e you can have one Pay-As-Talk SIM Card and one contract Sim in your phone, or two SIM's from two different networks. All you do, is turn your phone off, then on again, and it will 'read' the other SIM card. You really can have the best of both worlds!
