1. KingKing voice roaming service (“KK SERVICE”) is available only to CSL Mobile Limited subscribers and provided according to the terms & conditions governing your mobile service contract and special conditions for KK SERVICE.
2. KK SERVICE is compatible only with certain handsets. CSL Mobile Limited cannot guarantee KK Service performance in respect of incompatible handset models, nor call quality at every single Wi-Fi hotspot or any other place where Wi-Fi/mobile data service is available.

KK SERVICE charges will only be incurred when a customer uses KK SERVICE. If you have subscribed to another service plan, we will not charge you for KK SERVICE. IDD charges will apply if making calls to non-Hong Kong phone numbers. And local voice call minutes will be deducted/charged for the duration of such a call. Any charges for Wi-Fi connectivity, mobile data, IDD and or international roaming are additional. All mobile data usage of the service will be deducted from your monthly data entitlement or charged onto your account accordingly. Charges apply if you use KK SERVICE to send SMS and are calculated based on the SMS service (including intra-network, inter-network and international arrangements) provided by us, as if you were in Hong Kong.
4. Customers using KK SERVICE should download the latest KK SERVICE app to a mobile phone running iOS 13.0 or newer, or Android 9.0 or newer.
