I myself bought this phone samsung galaxy ace s 5830 two months back blindly .I thought this is a smartphone but I was shocked 2 know that it is not 3g compatible.My god my nokia N 90 2007 model is 3g compatible.Moreover battery life is pathetic charge on daily basis and if you use wi-fi or net , then you have to charge twice in a day.
In short, if you just want to buy a phone which is good in looks, touch then buy this phone but forget about 3g , battery problem and internal memory which is worst less then 200 mb .How can a big brand like samsung do this to its customers. In 14000 bucks, not compatible to 3g, very low internal memory poor battery. UNBELIVEABLE.
