Let me send ub05 to 10690700367. What is this?

Generally, this kind of message is used to verify some websites or software. First of all, you need to know whether the other person knows or doesn't know. If a stranger asks you to send this, you should pay attention. It's probably a stolen number. For example, if your mobile phone number is bound to an account of a website or software, such as, etc., the liar will pretend that his friend is missing and ask you to send a message to the designated number for verification. In fact, this verification code is an operation such as retrieving the password. Unless it is me, don't send it.
