Nokia announced on Tuesday the launch of Nokia Asha 310 , a new Dual SIM smartphone with Wi-Fi support to help people get more out of the Internet, for less. The powerful combination of Dual SIM plus Wi-Fi in the same device, a first for Nokia smartphones, gives consumers the best of both worlds by offering the flexibility to enjoy more mobile experiences while managing their costs. Nokia Asha 310 also comes packed with great apps and games that are the hallmark of the Nokia Asha range. Swap SIM cards: With Nokia's built-in Easy Swap Dual SIM technology, consumers can use the external slot on the Nokia Asha 310 to insert a secondary SIM card, while keeping their principal SIM card in place behind the battery. It puts the user in control, with the ability to shift between SIM cards for personal or work use without turning off the phone. They can also swap SIM cards while on-the-go, to get the best available tariffs when commuting. Nokia Easy Swap Dual SIM makes it possible to assign and store unique profiles for up to five SIM cards. Users can designate SIM cards for text, voice and data and switch between them at their convenience.
