Ronnie: Do you have any comment on the government’s requirement that you migrate all 3G subscribers to 4G? Could that lead to subscriber loss?

James: Yes, in accordance with NCC regulation, we have to terminate all 3G service by the end of the year, however 3G has to remain in the network because the voice service will fallback to the 3G network. So, even though 3G service is terminated, the 3G network will still remain. But we can use less spectrum for the 3G service. We used to have 15MHz for the 3G service including voice plus data, but since all 3G data service will be moved to 4G with the 3G network being used merely as a voice fallback, we will probably only use 5MHz for 3G. And the rest of the 15MHz spectrum will be used for 4G data services.
