Does the at&t contract go on your credit?

I'm begging my mom to sign the at&t 2 year contract so I can buy an iphone. Everything will be in her name but I will be paying it. I'm 17 and I have a job. Does this go on her credit? She says she won't do it if it goes on her credit. We're using a prepaid visa card to do everything online. We talked to at&t and they said we can use a prepaid visa card.

If will go on the credit report if she defaults on the contract. They will give it to a collection agency and they will be the once to report it to the credit bureau

It will only go on her credit report if she defaults on the account and it goes to collections.
There are MANY good prepaid options that go not involve having to get a credit check or cosigner.
You can get an iPhone with Virgin Mobile and it's no contract.
