Will I have to reactivate my SIM Card if I move it to another phone?

So I recently cracked my screen on my iPhone 5S (the reason isn't important and frankly embarrassing), and I have a spare 5C at home. Will I have to reactivate my SIM Card for my network provider? My provider is AT&T.

Nevermind, just spoke with AT&T, I don't need to. Don't bother posting answers.
