The person who sent the text message saw a fake number.

The other party received a fake number, probably because a virtual number was used. Virtual number refers to the number obtained through the network or mobile phone application, not the real mobile phone number, so illegal signals will appear in the address book and short message record. If you need to send real SMS, you should choose a regular SMS service provider and get the real mobile phone number through real-name authentication. At the same time, protect personal privacy and information security, and don't disclose and reveal your personal mobile phone number at will.
