Why is the Fetion message received by the mobile phone sometimes 12520+ mobile phone number, sometimes it is a flying signal, and sometimes there is only one name?

12520+ mobile phone number, because you disclosed your mobile phone number in the opposite direction, it shows Fetion service number+mobile phone number.

12520+ fetion signal, because the other party didn't disclose the mobile phone number to you, so it shows the fetion service number+fetion signal.

Remember: this is open to you, regardless of whether you are open to the other party.

There is only one name, that is, the landlord must have saved the other party's "12520+ mobile phone number" or "12520+ Fetion" as the address book contact.

The landlord can inquire whether his address book is stored in this way. . .
