Why do I keep getting text messages from 5 173?

And LZ's mobile phone number The last phone number left by the user of your number when registering is 5 173. LZ can ignore him. My mobile phone number is like this. People always call someone, and in their dialect, they will receive such a call in a few days. In fact, LZ doesn't have to worry about him, just hang up, it doesn't affect you. .
