I can't register an account in iTunes?

I recently got an iPhone as a present from my mom then I tried to install a game on it (I already know how to download games)but after trying to register an account. I was shocked to see that there's no option on the credit card list that says "nothing" which means I have to register a credit card and I don't have one Please help (I'm by the Philippines by the way)

Use another Email to sign in iTune…

There are only TWO ways to set up an iTunes STORE User Account using the free iTunes App, on your iPhone, or your home computer:

(1) Get your own Credit Card, (or ask Mom if you can use hers). (2) BUY an iTunes Gift Card locally.

Then, on the same screen that asks for Credit Card info, there's an Option to enter Gift Card info instead, although they may need your Mom's Credit Card as well. After all it is a STORE, not a music PIRATING website.
