I woke up to the phone ringing. My mother says that it's hard for her to hear me on the phone and that I should get a new cell phone.

What? Just because it has a crack that reaches across the face and one side of the flip joint is broken so you can't hear through the actual phone and need an earpiece to listen and talk doesn't mean it's not a perfectly functional phone.

Notice the language. I said "functional" not "good". Subtlety is art when you don't have to point it out to others.
