A parent mobile station (100) may establish a communication link (106) via a wireless network (104) using any appropriate technology. The parent mobile station (100) may send a control message over the communication link (106) which causes the child mobile station (101) to take various actions including being forced to call back the parent mobile station (100) upon any detected user action on a user interface of the child mobile station (101). For example, the child mobile station (101) may be locked such that no calls may be placed. Other actions of the child mobile station (101) may also be blocked such as, but not limited to, text messaging and Internet access. The command message may be a Short Message Service (SMS) message, a Session Initiation Protocol (SIP) message or any other appropriate message.
