11. The method of claim 10 , wherein the location-based operating parameter is a country name.

12. The method of claim 10 , further comprising registering with the first wireless network.

13. The method of claim 10 , further comprising updating the location-based operating parameter from the second wireless network by listening to a broadcast channel and not by sending data to the second wireless network.

14. The method of claim 10 , further comprising searching for the second wireless network, wherein the second wireless network is of a different network type than the first wireless network.

15. The method of claim 10 , wherein the location-based operating parameter is a mobile country code.

16. The method of claim 15 , further comprising determining a country name utilizing the obtained mobile country code.

17. The method of claim 15 , further comprising checking the validity of the location-based operating parameter by determining whether the obtained mobile country code is an expected value.

18. The method of claim 15 , further comprising:

identifying a frequency range of the second wireless network;

selecting a frequency within the identified frequency range;

detecting a signal from the second wireless network; and

updating the location-based operating parameter from the second wireless network by utilizing a broadcast channel.

19. The method of claim 10 , wherein the first wireless network is one of a CDMA and a non-CDMA wireless network, and the second wireless network is one of the other of a CDMA and a non-CDMA wireless network.

20. A non-transitory computer-readable medium comprising instructions tangibly embodied thereon, the instructions executable by a processor for:

receiving a request for a location-based operating parameter;

updating the location-based operating parameter from a first wireless network;

checking the validity of the location-based operating parameter from the first wireless network;

if the location-based operating parameter from the first wireless network is not valid, then

searching for a second wireless network of a second network type, and

updating the location-based operating parameter from the second wireless network; and

utilizing the location-based operating parameter obtained from the second wireless network to provide the requested location-based service via the first wireless network, wherein the service includes providing a dialing service to the first wireless network for initiating an international communication based on the location-based operating parameter from the second wireless network.

21. The medium of claim 20 , wherein the location-based operating parameter is a mobile country code.

22. The medium of claim 20 , further comprising instructions for checking the validity of the location-based operating parameter by comparing the location-based operating parameter to at least one expected value.
