Samsung B5722 Dual SIM + microSD 8GB
The Samsung B5722 handset simultaneously supports two SIM cards, at which the first card covers 850, 900, 1800 and 1900MHz, and the second 900 and 1800MHz SIM. The infrastructure for the operation is Samsung's TouchWiz Lite 1.0, so that the dual SIM technology is optimized for an extremely user-friendly touch-screen operation. According to the latest information, social networking applications such as Facebook and MySpace are already preinstalled on this phone, so if you're a fanatic social network fan, you can get started right away.
 

Samsung Dual SIM mobile phone
When it comes to the camera application, the Samsung B5722 Dual SIM mobile phone is relatively easy-going. With a resolution of 3 Megapixels, the B5722 from Samsung has the dubious honor to be at the top of the list of low resolution camera phones. However, if Samsung has actually genuinely focused on the pixel quality of the 3 megapixel digital camera, you will not hear one complaint from us. The memory of the Samsung B5722 Duos is expandable by an SDHC memory card with a maximum storage capacity of 8GB. It would not come to us as a surprise if the B5722 also supports 16GB.
