My new mobile phone number has been receiving strange text messages.

Your newly purchased mobile phone number is a mobile phone number that was previously used by others for various reasons (for example, cancellation, shutdown, etc.). After the operator takes it back, it will be released to others after half a year or more. The person who originally used this number, his original customer or others, did not know that he had abandoned this number, but still sent him relevant information. So, you become his receiver.
