Best Plans for China & Greater Bay Area Data
Every plan below includes Mainland China or Greater Bay Area data, or a roaming day-pass. If you cross the border regularly, a bundled China/GBA allowance is far cheaper than paying daily roaming — and HK-routed data reaches services a local Mainland SIM may block.

Frequently asked questions
Can my Hong Kong plan work in Mainland China?
Many Hong Kong plans include a Mainland China or Greater Bay Area data allowance so your HK SIM works across the border without a separate China SIM, usually more cheaply than roaming.
