What is the account code of Tianlong Babu SMS binding account?

A mobile phone number can only be bound to three accounts at most. If you only bind one account, you can enter TLSD without coding, such as locking and unlocking TLJS lines. If coding is necessary, add 1 after the English letters. If three accounts are bound, the first account code is 1, the second account code is 2, and the third account code is 3. Take it. That's right.
