Nokia Lumia sucks, it has almost no available app. The apps that are there are super outdated and buggy. You're better off with a cheap android, trust me.
Im a former nokia lumia owner, before i threw it to the wall the flushed it down the toilet.
Go out there and invest into an Android phone.
HTC One M8 is my recommendation.
Or Samsung, or a Nexus.
Don't waste your time with an iPhone. Unless you are bad with phones/technology then buy a 6/5
