In the last two months, you have often received electricity bills from other people's homes. You can ask the mobile operator why other people's text messages are sent to your mobile phone number. This may be because the person who paid the electricity bill used your mobile phone number before and returned it, so his original contact information will still be sent to this number. You can ask the mobile operator to close this short message, or you can send this short-arm short message for blackmail.
