Mobile Communications Services at the Huanggang Port Hong Kong Port Area
The Huanggang Port is situated within Shenzhen, with the Hong Kong Port Area and the Mainland Port Area sharing the same interior space within the building. To maintain smooth operation of the port, and to avoid mutual interference of radio signals of Mainland and Hong Kong mobile networks, the mobile communications services throughout the entire Huanggang Port (including the Hong Kong Port Area) are provided by Mainland mobile network operators as approved by the Mainland authorities.
How to Use Mobile Communications Services
Members of the public who wish to use mobile communications services at the Huanggang Port should apply for roaming services from their Hong Kong mobile network operators in advance. If users’ mobile phones have already roamed onto Mainland networks, phone calls made or received and mobile data usage for internet access at the Huanggang Port will be regarded as roaming calls and roaming data usage respectively, and will be charged at roaming rates.
Major mobile network operators offer a variety of mobile service plans that include Mainland roaming usage. Members of the public may consider subscribing to such service plans, or using roaming pre-paid SIM cards or Mainland SIM cards for connecting to Mainland mobile networks.
Emergency Calls via Mobile Communications Services
If a member of the public’s mobile phone has already roamed onto a Mainland mobile network, please call 00852-3661-1733 to contact the Hong Kong Police Force’s Huanggang Port Reporting Centre. When using the roaming service, members of the public will NOT be able to contact Hong Kong’s 999 emergency call centre by dialling 00852-112 or 00852-999.
If the mobile phone is unable to connect to the subscribed network, users may try calling 110 (police), 119 (fire services), or 120 (ambulance) to reach the Mainland emergency services. Should the incident reported occur within the Hong Kong Port Area, the Mainland authorities will contact the Hong Kong side for follow-up.

Government Wi-Fi Service User Guidelines
To facilitate members of the public to use Internet services in the Hong Kong Port Area, the Hong Kong Government provides free public Wi-Fi network coverage within the port building, including the public transport interchange. Members of the public simply need to turn on the Wi-Fi function of their mobile devices, select “Wi-Fi.HK” from the list of available Wi-Fi networks, and then click “Connect”. Once successfully connected, they can use the service without prior registration.
By using the Hong Kong Government Wi-Fi service, users agree to and unconditionally accept the “Conditions of Use and Disclaimers for the Use of Government Wi-Fi Services”. For details of the Conditions of Use and Disclaimers, please visit (https://wi-fi.hk/GovWiFi_TandC.html#en).
Free public Wi-Fi service is shared resources that are intended to meet the general Internet needs of the public during boundary crossing, such as browsing the web, accessing information and using general online services. Since the service is shared by all users, the performance of certain high-bandwidth applications (such as video streaming, large file downloads or uploads) may be affected during peak traffic or usage periods.
Wi-Fi signal strength is susceptible to various objective factors, including the distance between the Wi-Fi hotspot and the mobile device, the number of people simultaneously connecting and using the service, user distribution, interference from building structure, obstacles and other surrounding wireless networks, the performance of the mobile device and the orientation of its antenna, and the load of the website or application being browsed. Therefore, actual connection speed and user experience may vary depending on the time, location and usage.
Generally, the signal is stronger near areas marked with “Wi-Fi.HK” hotspot signage within the premises. We recommend that members of the public connect to the Wi-Fi in the vicinity of these signposted areas to enjoy a more stable Wi-Fi service.
