Haha, is SMS binding safe?

Because I saw you asked a question in the QQ section, I wonder if you are asking about SMS binding for Tianlong Babu account. It costs 100 Sohu Card points to bind an account. There is no charge for account operations. Only the information fee is paid to the operator. It is relatively safe.

As for QQ. It is recommended that you use your mobile phone to bind it. No hassle and no fees. Just when you operate your QQ account, you have to pay the information fee to the mobile phone operator.
