How much is more storage for iPhone 5?

My iphone 5 tells me that i need to buy more storage and I think I need 5.9 gigabytes more or something like that… Does anyone know how much that will be? Xx

First of all you can't buy strorage to your iphone and if its 5 then you have minium of 32 gb so chill!

Yeah the comment above me is right you can't buy more storage or can follows these steps to find out how much storage you have left.

1)Go to settings
2)Then go to general
3)Then go to Usage
4)Then when that loads find the word storage and look under that word and it will say blahh blahh Gb available
and your done

IPhones don't have the option of expandable memory. You'd have to buy a newer higher capacity model to get more space.
