Yes i believe it is Quad band so it will work almost everywhere. 1gb of ram is the best you can get for that price range and that will be sufficient for your requirements. You may check this for more info Asus Zenfone 4 A450CG - Full phone specifications

My son is using a samsung galaxy V it's has a much lower specs than the zenfone but it works well. You can try that also if you're brand concious but other than that I'd recommend the ASUS.
