Methods for remote control of a wireless unit such as remote power-on and remote power-off. An authorized user may send a power-on communication to a remote wireless unit. The power-on communication may be sent by way of an activation system. The wireless unit may be in a sleep state or be turned-off. In response to receipt of the power-on communication or a signal from the activation system, the wireless unit powers-on and may power-on through a remote power-on function. The power-on communication or the signal that initiates the power-on may include a security mechanism necessary to power-on the wireless unit. The user may be provided with confirmation of the power-on of the wireless unit, or the user may be connected in a communication with the wireless unit. Similarly, a wireless unit that is powered-on may be remotely powered-off.
