Coverage and networks

Hong Kong has four mobile operators: CSL Mobile, 3 (Three) Hong Kong, SmarTone and China Mobile Hong Kong (CMHK). Together they cover almost the entire city-state with availability of more than 98 percent. CSL has more than 95 percent 4G coverage, while CMHK excels in 5G speeds. Thanks to the compact area, coverage is strong everywhere, including in metro stations and on islands such as Lantau. Networks: CSL Mobile, 3 Hongkong, SmarTone.

For a city trip of a few days, 3 to 5 GB is usually enough. If you travel onward to mainland China, choose a bundle that covers mainland China separately or supports a VPN.

Hong Kong does not fall under the Great Firewall of mainland China, so Google, WhatsApp and Instagram work normally there, unlike in mainland China.
