Data in a dense city
In Hong Kong the plan uses the SmarTone and csl networks. Coverage across the city is excellent: Hong Kong Island, Kowloon and the New Territories, plus MTR stations and tunnels, generally work well. The starting points of most island trips and hiking trails are covered too, but on remote trails on Lantau and in the New Territories the signal can weaken.
In Hong Kong, Google, WhatsApp and the other familiar services work normally, unlike in mainland China. If you make a day trip to Shenzhen or Macau, the plan may not work there, since those places are on different networks. Check separately whether your plan covers them.
A local SIM is available at the airport and in shops, and it needs your passport and often a queue. The eSIM is installed before you leave and the data starts on arrival. Your own number stays with you, and WhatsApp calls run over data. Hotel wifi is usually usable, but your own data makes getting around town easier. Roaming on your own plan is often dearer than a separate data plan.
