I ordered an Iphone do I need to Sign?

I cracked my old phone and I have insurance on it so AT&T is sending me a new one. They handed me a paper with no helpful info. It doesn't say what company is delivering it and there's no tracking number. I won't be home much tomorrow and I have no clue of the package will arrive tomorrow or Tuesday. Will I have to sign? Its a 4s.

Added (1). It shouldn't be a big package. I'm 15 so Will I need someone else to sign for it?

It depends who you orrdered from most of the time you do if your not older than 18 than someone else can sign it

Unless it is a very big package, you do not have to sign. All you have to do is sign and get on with your life… Its not a big deal.
