There is not much difference in both the Single SIM and the Dual SIM devices but in Dual SIM version you will be able to take the back cover off and then see the SIM Slots and external memory slot. Both the SIM slots will not support the 3G connectivity rather the secondary SIM slot will not support the 3G but only Edge on the phone. The display size of the device is 4.7 Inches with the pixel density of 468 PPI (for FULL HD Display). This will also have a Quad Core Processor where the cores have been clocked at the frequency of 1.7 GHz and this will also be supported by 2GB RAM (giving the power enough to the smartphone to perform in the decent manner). The internal memory storage available in the device is 16GB can be further taken up to 64GB with the help of microSD card. You will also get a Dropbox storage plan of 25 GB (not certain for the number of years for which this will be available to you).
