Abstract

A method and apparatus for unlocking a mobile station operating in a limited service state, the method having the steps of: storing one or more predetermined contacts on the mobile station, and allowing, while said mobile station is operating in the limited service state, the mobile station to communicate with the one or more predetermined contacts, whereby the one or more predetermined contacts allow a user to obtain unlocking information for the mobile station.

Claims

1. A method for unlocking a mobile station operating in a limited service state comprising the steps of:

storing one or more predetermined contacts on the mobile station, and

allowing, while said mobile station is operating in said limited service state, the mobile station to communicate with said one or more predetermined contacts,

whereby said one or more predetermined contacts allow a user to obtain unlocking information for said mobile station.

2. The method of claim 1, wherein said allowing said mobile station to communicate step utilizes a voice channel.

3. The method of claim 2, wherein said storing step stores one or more voice telephone numbers.

4. The method of claim 3, wherein said one or more voice telephone numbers include a corporate IT telephone number or a customer service number of an operator subsidizing the mobile station.

5. The method of claim 4, wherein communicating with said corporate IT telephone number or said customer service number provides a user with an unlock code for the mobile station.

6. The method of claim 4, wherein a user communicating with said customer service number is provided with an option to purchase a subsidy on said mobile station.

7. The method of claim 1, wherein said allowing said mobile station to communicate step utilizes a data channel.

8. The method of claim 7, wherein said storing step stores one or more web addresses.

9. The method of claim 8, wherein said communicating step limits communications from said mobile station to browsing said one or more web addresses stored by said storing step.

10. The method of claim 7, wherein said storing step stores one or more email addresses or one or more SMS addresses.

11. The method of claim 10, wherein said communicating step limits communications from said mobile station to sending and receiving emails or SMS messages from said email and SMS addresses stored in said storing step.

12. The method of claim 11, wherein said method further comprises the steps of:

receiving an email or SMS message from an email or SMS address stored in said storing step; and

unlocking said mobile station automatically if said email or SMS message includes a correct unlock code.

13. The method of claim 11, wherein said method further comprises the steps of:

receiving an allowed email message; and

unlocking said mobile station based upon said allowed email message.

14. A mobile station operable in a limited service state comprising:

a processor;

a memory coupled to the processor, said memory adapted to store one or more predetermined contacts;

a user interface;

personalization data stored in the memory;

a radio coupled to the processor; and

a depersonalization module adapted to allow, while said mobile station is operating in said limited service state, the mobile station to communicate with said one or more predetermined contacts to allow a user to obtain unlocking information for said mobile station.

15. The mobile station of claim 14, wherein said depersonalization module allows communication over a voice channel.

16. The mobile station of claim 15, wherein said memory is adapted to store one or more voice telephone numbers.

17. The mobile station of claim 16, wherein said one or more voice telephone numbers include a corporate IT telephone number or a customer service number of an operator subsidizing the mobile station.

18. The mobile station of claim 17, wherein said communication by said depersonalization module is adapted to provide a user with an unlock code for the mobile station.

19. The mobile station of claim 14, wherein said depersonalization module allows communication over a data channel.

20. The mobile station of claim 19, wherein said memory is adapted to store one or more web addresses.

21. The mobile station of claim 20, wherein said depersonalization module is adapted to limit communications from said mobile station to browsing said one or more web pages stored in said memory.

22. The mobile station of claim 14, wherein memory is adapted to stores one or more email addresses or one or more SMS addresses.

23. The mobile station of claim 22, wherein said depersonalization module is adapted to limit communications from said mobile station to sending emails or SMS messages to said email and SMS addresses stored in said memory.

24. The mobile station of claim 22, wherein said depersonalization module is adapted to limit communications to said mobile station to receiving emails or SMS messages from said email and SMS addresses stored in said memory.

25. The mobile station of claim 23, wherein said mobile station is further adapted to receive an email and unlock said mobile station automatically if said email or SMS message includes a correct unlock code.

26. The mobile station of claim 23, wherein said mobile station is further adapted to receive an email message from an email address stored in said storing step and unlock said mobile station upon a user clicking a hyperlink in said email.
