I purchased this mobile to gift someone .the mobile Samsung Metro B313 is very good mobile. This mobile supports dual sim and has music player , video player, bluetooth, camera, Fm, external extented memory card support upto 32gb. The main thing of this mobile is very good battery backup , generally it gives 3days battery backup. It is very easy to use and stylish in look. It has keypad no tochpad.
Both of the sims works at a time. It is very good phone in case of price and facilities. I can use whatsapp , facebook, twitter on this phone also. There is gprs in this phone. Allover its a good phone with a brand name of samsung.
