QQ Sync Assistant can back up the business cards and SMS messages in the phone to the network, or restore them from the network to the phone. The network storage is complete and stable. Use the smart synchronization function to synchronize only the changed business cards in your phone or network, saving your traffic and time. It only takes 3-5 seconds to back up the business card in the phone to the memory card, which is faster than the backup function provided by the phone. Professional digital certificate encryption is used to conduct security authentication for websites and mobile phone clients to ensure the security of your personal private information.
