3HK
 
As the first local telecom operator to connect with all major mobile networks in mainland China, 3 Hong Kong is proud to offer our "Cross-network Roaming*" service, which now extends to popular travel destinations that are top favourites for Hong Kong people. These destinations include Japan, South Korea, Thailand and Australia.

You can instantly connect to all mobile networks while travelling, ensuring a seamless experience for dining, shopping, sightseeing, or in-depth exploration. Bid farewell to the inconvenience of local SIM cards and stay connected throughout your journey.

What is "Cross-network Roaming*"?
Cross-network Roaming*
No SIM swaps. You can instantly connect to all network providers upon arrival. When there is no signal at a particular location and time, it will automatically switch to the best network at that moment!
Without Cross-network Roaming
With a single SIM card, you can only connect to one network provider. If you encounter a weak signal, the only options are to buy another SIM or move to an area with a stronger signal.
