Can you add more gb on your iphone 4s?

I'm new to this & my mom ordered it online for my 14 birthday. Its a 16gb 4S. & i'm just wondering if you use all your gb… How can you add more?!

The iPhone is not upgradable so you won't be able to add more to it once you get it.

Some phones do allow micro SD cards but I don't think the iPhone is one of them.

It takes a lot to fill up a 16gb card with typical usage, unless your going to use it to watch videos and use it for music you should be fine.

I have an iPhone 5s and I have 16gb on it would I be able to try and have it 32gb?
