Abstract

The present invention provides a method (300) of operating a wireless communications device, and comprising identifying a wireless network for communicating with the device in response to receiving subscriber provided network identity data (315), activating a restricted use mode restricting communications between the wireless network and the device (320), receiving network provided network security data from the wireless network (330) in response to a request for the network provided network security data transmitted from the device to the wireless network (325), deactivating the restricted use mode (350) in response to determining that subscriber provided network security data corresponds to the network provided network security data (340Y).

Claims

1. A method of operating a wireless communications device, the method comprising:

identifying a wireless network for communicating with the device in response to receiving subscriber provided network identity data;

activating a restricted use mode restricting communications between the identified wireless network and the device;

receiving network provided network security data from the identified wireless network in response to a request from the device to the identified wireless network; and

deactivating the restricted use mode in response to determining that subscriber provided network security data corresponds to the received network provided network security data.

2. A method of operating a wireless communications device as claimed in claim 1, wherein the subscriber provided network identity and security data is received from a removable module containing said data.

3. A method of operating a wireless communications device as claimed in claim 1, further comprising activating a restricted service provider lock which restricts communication between the device and another wireless network by securely storing the network provided network security data on the device and activating a restricted use mode unless this corresponds with the subscriber provided network security data.

4. A wireless communications device comprising:

a processor and memory;

the processor arranged to identify a wireless network for communicating with the device in response to receiving subscriber provided network identity data;

the processor further arranged to activate a restricted use mode restricting communications between the identified wireless network and the device;

a transceiver arranged to send a request to the identified wireless network for network provided network security data, and to receive said data; and

the processor further arranged to deactivate the restricted use mode in response to determining that subscriber provided network security data corresponds to the received network provided network security data.

5. A device as claimed in claim 4, further comprising a secure memory for storing the received network provided network security data, the processor further arranged to restrict communication between the device and another wireless network unless the securely stored network provided network security data corresponds with subscriber provided network security data.

6. A device as claimed in claim 4, further comprising an interface for receiving a removable module having the subscriber provided network identity data.

7. A wireless communications system having a wireless network and a number of wireless communications devices, the devices each comprising:

a processor and memory;

the processor arranged to identify the wireless network for communicating with the device in response to receiving subscriber provided network identity data;

the processor further arranged to activate a restricted use mode restricting communications between the identified wireless network and the device;

a transceiver arranged to send a request to the identified wireless network for network provided network security data, and to receive said data; and

the processor further arranged to deactivate the restricted use mode in response to determining that subscriber provided network security data corresponds to the received network provided network security data.
