1. A mobile phone, comprising:
- a near field communication (NFC) radio transceiver included in the mobile phone;
an NFC radio antenna included in the mobile phone; and
a coupling component included in the mobile phone that;
couples the NFC radio antenna to the NFC radio transceiver when selected to a first state, anddecouples the NFC antenna from the NFC radio transceiver when selected to a second state in response to receiving an NFC deactivation request from a cellular wireless network, wherein the NFC deactivation request is sent in response to an indication that the mobile phone has been misplaced, and wherein the NFC antenna remains decoupled from the NFC radio transceiver in response to receiving the NFC deactivation request until an NFC radio system activation request is received from the cellular wireless network.

7. A method of operating a near field communication (NFC) radio system in a mobile phone, comprising:
-
receiving, by an application stored in a non-transitory memory of a mobile phone and executable by a processor of the mobile phone, a deactivate message via a cellular radio transceiver included in the mobile phone from a cellular wireless network, wherein the deactivate message requests deactivating a near field communication radio system included in the mobile phone, wherein the NFC deactivation request is sent in response to an indication that the mobile phone has been misplaced; in response to the deactivate message, disabling, by the application, an antenna functionality of the NFC radio system included in the mobile phone until an activate message is received from the cellular wireless network; receiving, by the application, the activate message via the cellular radio transceiver from the cellular wireless network, wherein the activate message requests enabling the NFC radio system included in the mobile phone; and in response to the activate message, enabling, by the application, the antenna functionality of the NFC radio system included in the mobile phone. - View Dependent Claims (8, 9, 10, 11, 12)

13. A portable electronic device, comprising:
-
a cellular communication radio transceiver included in the portable electronic device; a near field communication (NFC) radio transceiver included in the portable electronic device; an NFC radio antenna included in the portable electronic device; a processor included in the portable electronic device; a memory included in the portable electronic device; and an application stored in the memory that, when executed by the processor, based on the cellular communication radio transceiver receiving an NFC radio disable criterion message from a cellular wireless network, selectively disables the NFC radio antenna and enables the NFC radio antenna based on a criterion provided in the NFC disable criterion message from the cellular wireless network, wherein when the NFC radio antenna is disabled, the NFC radio transceiver is not able to transmit or receive NFC messages. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
