✔ 最佳答案
I have been call OFTA and ask them "can I provide the IMEI and block the mobile device"
their answer is "NO this service at HK"
As I know USA and Canada's Telecommunications Authority . can use the IMEI to block the device. but U must submit the invoice or service provider documents for STOPPING the device in-use.
I think OFTA MUST add this service at HK, can be STOP all illegal mobile trade.
