Mainland phone number, how to call Chinese mainland's family when traveling to Hong Kong?

You can use mainland mobile phones in Hong Kong, open international roaming in advance, or ask for prepayment, which is expensive. It is recommended to consult the mobile phone operator directly.

The common practice is to carry a mainland mobile phone and open an international roaming service, and then prepare a spare mobile phone. After arriving in Hong Kong, buy a local mobile phone card for making phone calls and surfing the Internet.
