What if the contact stored in the mobile phone sends a text message without displaying his name?

First, you may have saved the same contact twice, that is, Zhang San has two numbers in the mobile phone address book, one is the mobile phone number and the other is the landline number. Don't give a person different numbers, but let a person have several numbers under his name.

Second, it may be the same mobile phone number, and your address book has chosen a SIM card and a mobile phone. At this time, you need to adjust, try not to choose SIM card and mobile phone in the address book settings, both mobile phone and SIM card can be used.

Third, you have contacts in your mobile phone, but you prefix your mobile phone number with 12593 or 1795 1. It would be nice if you removed it.
