Data roaming is when you use your phone’s mobile data connection to stay connected in overseas. In Hong Kong, your phone will connect to mobile networks run by local providers. The big 3 Internet providers in Hong Kong are 3 Hong Kong, SmarTone, and China Mobile.

By default, your home carrier will charge you rates to use these foreign networks when roaming in Hong Kong. The rate of data can vary but the price is still expensive per megabyte of data used.

To avoid roaming charges, you can buy a local Hong Kong SIM card, or instead of using data, you can connect to a Wi-Fi network to use the free Internet. Public WiFi is widely available throughout Hong Kong at malls, cafes, and on subway lines. Using WiFi is a good way to avoid cellular data charges.
