After two weeks of intensive testing dual sim and despite my reluctance to buy from seeing the reviews, I plurtot satisfied. Apart Amazon deliveries that are still excellent, this smartphone perfectly answer my expectations. I use it in dual sim every day, the battery fits easily the day with non-stop 3G, 4 mail boxes in push (aquamail), facebook, Snapchat, insta, twitter, messenger, news, weather that runs in the background. No bugs found yet. GPS issue, it works perfectly with Waze and after several long drive. So no bp GPS as many points out. My only regret (and I have the impression that Wiko'll take the bad haibitude) is to be forced to choose between SD and second sim. Should not that Wiko fun too has this kind of thing because the dual sim is a strength for them in France. That said, Getaway to 16 G of internal memory which is enough for normal use. (I must have two games has to break everything in my phone). Hoping Wiko migrates under lollipop ... but should not be dreaming;) So in conclusion, you could buy it without pb, you will not be disappointed. I buy with a small silicone shell sold 12 Euros. The war népaissis shell phone in the pocket.
