Specifications mobile dual sim adapter for apple iphone bluetooth dual sim adapter 1. new design,fast delivery 2. smart mobile adpter For iPod Touch UsersJust connect your iTouch to SocBlue and your iTouch will be immediately transformed into a powerful iPhone which not only has the voice calls, short messages and Internet accesses function but also has the Dual SIM/Standby characteristics. The amount cost of one iTouch and one SocBlue will be far less than that of one iPhone while its function will be more powerful than iPhone’s. For iPhone UsersLike iPhone but it is single-card designed.What if we need to use two cards or three cards for various reasons?Carrying iPhone and another high-end phone at the same time will be too heavy and uneconomical, also an iPhone with a low-end phone will degrade our identity with less aesthetic pleasure.How eagerly we are looking forward to having a magic prop to perfectly solve this problem!Now,SocBlue is coming.
