One possibility is that you saved the same contact twice, that is, Zhang San has two in the mobile phone address book, one is the mobile phone number and the other is the landline number. Don't save different numbers for a person, but let a person have several numbers under his name. Second, it may be the same mobile phone number. You have a SIM card and a mobile phone in your address book. At this time, you need to adjust and try not to choose SIM card and mobile phone in the address book settings. It's either a mobile phone or a SIM card. Third, you have a contact stored in your mobile phone. You can add the prefix 12593 or 1795 1 before the mobile phone number to see if it is. It would be nice if it were removed. In addition, whether it is a local call or a foreign call, just add the long-distance area code to the landline. For example, if the person is a local-Beijing, it will be added when editing. Including PHS, please be careful not to add any symbols between the area code and the number when editing the landline and PHS, just 0 108222 XXX. Of course, the name should be displayed at this time, even if it is local, the area code should be added when dialing. Friends try ~ ~ ~
