KingKing^{(1)(2)(4)(5)(6)} from 1O1O is a VoIP application, based on Wi-Fi or mobile network connectivity that can be used in Hong Kong or while overseas.

• You can use your existing 1O1O number and have your caller ID displayed to people you call, and see the ID of those calling you.

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.
