If you are out looking for a hardware QWERTY Dual SIM device that delivers on email (POP3/IMAP), basic web browsing, and social networking, perhaps you should consider the LG C310.
The C310 has dual standby functionality, meaning that both lines are active simultaneously. Network data is GPRS and EDGE. There’s only 15MB of memory built in, but then there’s a microSD slot that is compliant with cards up to 4GB.
The keys are large and comfortable to use, and the display is TFT. The camera is only 2megapixel, but that is to be expected of a device in the price range of N20,000. There’s also Bluetooth, microUSB, music player, video player, and a number of other features.
