I have no storage on my iPhone 5?

I don't have any storage on my phone. I don't have that many pictures and barely any apps. It's so annoying bc I can't take pictures, update apps, or get the newest update for my phone. I try deleting pics and messages but it doesn't do anything. Any advice on how to get more storage or anything would be appreciated.

What to look for when buying a iPhone?

I'm looking to buy a used iPhone 5 but I have a couple questions.

First of all, I plan on unlocking the iPhone so I can use Lyca Mobile as a carrier on it. I was told that I can't buy a Sprint iPhone with esn because esn means that it was reported lost or stolen or something like that, so it won't work with Lyca Mobile.

So as some questions:
Is what I heard true or not, or can I buy the Sprint iPhone to unlock?
If not, what should I look for when buying a iPhone to unlock later on (Special carrier, IMED, ESN etc.)?
Can I buy any iPhone and unlock it to use on Lyca Mobile?

-Thanks

My main question is will the Lyca Mobile SIM card work on the Unlocked Sprint iPhone 5?

What does No contract mean (iphone5s)?

Okay so I'm saving up to buy the iphone5s, I have verizon. I was told that getting it with no contract would be better. But my friends said that having no contract means I can't have; internet, unlimited texting or calls, and that basically it would be as good as an ipod. They also said that you have to have a contract. This doesn't make sense though cause why would the no contract be more expensive, if it meant that you can't get all the features I mean it is an iphone so isn't that the point? I know that for a 2 year contract you pay monthly or something and I can't do that (16 with no job). So my questions are:

What does it mean to have "no contract" for an iphone5s?

Is it better/ worth it to have no contract?

Can I still have unlimited texting/calls, internet with no contract?

and ya if someone can just clarify it would be very much appreciated thanks and sorry if it was confusing.
