How do you turn on a Nokia cellphone?

Most Nokia Phones have the power button at the top; try pushing it or holding it in for a couple of seconds. If that doesn't work, then the battery may be dead or the phone itself may be broken; or your cellphone may be locked, requiring you to unlock and then turn it off.

A few Nokia models require you to press the "C" key for a couple of seconds to start them. Others require you to push and hold a red button on the side.
