Tencent King Card is directly free of traffic for QQ Music and does not need to be activated. Even if there is no free traffic mark, no traffic charges will be incurred, but you need to ensure that you are using a 3Gnet access point. If China Unicom Tencent King Card users cannot enjoy free streaming when using QQ Music, they can contact the local China Unicom customer service hotline to provide feedback for verification and processing.
