HI , Just bought this phone on Ebay and reached what i needed , multiple features in a compact phone . As i've seen on different blog's this phone has all i needed Dual sim , Wifi & lots of other things , one thing im gonna question that even the seller wasn't sure about it , Is there any button somewhere around that you can switch from one sim to another directly by pressing it ??? I had a Samsung B5722 dual sim and was practically handy with that small button where you could choose by a click of a button from one side to another .. !!! Is it visible a button in the edges near the screen ??? Thanks hope to hear soon from you guys !!!
