Well talking about wallet these days is like you do not need to carry money in to your pocket if you using wallet like this but when it comes to the Oxigen wallet it is the worst wallet I have ever used.If you are adding money into the wallet there is a charge on adding money to the wallet and transfering it and if you transfer also there is a charge but if you talk about other apps they do not charge you.Well it was the first wallet which was introduced in the market and still not famous because no one likes to use it.
