How much will it cost for your trip?
Hong Kong is a separate telecommunications jurisdiction from mainland China. A China eSIM will not work in Hong Kong, and a Hong Kong eSIM will not work in mainland China. If your trip includes both, you need two separate eSIM plans or a HK+China combo plan. Note that Hong Kong has no Great Firewall restrictions — you can access Google, WhatsApp, Facebook and VPNs freely. Mainland China has the Great Firewall and requires a VPN installed before arrival.
Hong Kong's Octopus card is a stored-value card used for MTR, buses, ferries, trams, most taxis, convenience stores and many restaurants. Buy one at the airport on arrival ($50 HKD deposit). It's almost more essential than cash for getting around. For data, any of the four Hong Kong operators deliver excellent 5G speeds. Download Google Maps offline as a backup for outlying island hiking.

eSIM — Hong Kong
Network coverage in Hong Kong
Hong Kong has four mobile operators — CMHK, HKT, 3HK and SmarTone — all operating 5G. Across Kowloon, Central, Wan Chai, Tsim Sha Tsui, Causeway Bay and the main MTR corridors, all four perform well with 4G/5G. Differences emerge in the New Territories countryside and on the Outlying Islands, where CMHK and HKT have broader coverage, while SmarTone is regarded as the strongest inside MTR tunnels and indoors.
Among the providers on this page, Airalo routes via 3HK. aloSIM's Hong Kong carrier is reported inconsistently (CMHK or 3HK). Roamless network not confirmed. Saily and Yesim do not disclose their Hong Kong carrier. For outlying island hiking and rural New Territories, see the field tip above. Travel eSIM providers on this page route via one of the four operators — routing varies; check each provider card for the carrier listed.

VPN, passwords and documents
On hotel or café Wi-Fi, a VPN can be useful to keep your browsing private from the network operator. A password manager is also worth having for managing account access on the road. A secure cloud backup of your passport, visa, insurance and accommodation details can also be useful — keep an offline copy too. None of these are mandatory.
