A strange number sent a text message to my mobile phone, and the other party didn't answer. How will it affect me?

Generally, it will not have a big impact.

Generally, there are two situations: one is to convey the wrong information for others; The second is to swindle short messages by phone and charge high phone bills (there is something wrong with that number)

Don't reply to strange text messages and numbers easily. It is the basic ability to prevent being cheated at ordinary times. Please remember.
