The government is being urged to follow the American approach to tackling mobile phone theft by setting up a centralised reporting system with key service providers.
But the Office of the Communications Authority (OFCA) said technical difficulties could undermine the effectiveness of such a system.
The US Federal Communications Commission on Tuesday said it would launch a scheme to combat mobile phone theft, under which a centralised database would be set up to track stolen phones and to prevent them from being used again.
The new database will store the unique serial numbers of mobile phones - known as the International Mobile Equipment Identity (IMEI) number. Anyone whose phone is stolen will be able to report it to their service provider, who will enter the IMEI number into the database to prevent the device from being reactivated by another service provider.
The system - which requires collaboration with major wireless phone service providers - is expected to be up and running across the US in 18 months.
Hong Kong has a mobile phone penetration rate of 180 per cent, according to a global study.
