High score. Why doesn't the phone stored in my mobile phone show my name when calling me or texting me?

First, please make sure that all phone numbers have been copied from the sim card to the mobile phone.

If your business card is stored in the SIM card, you can't display the related name when you make a phone call or receive a short message, only the name stored in the card holder can be displayed. In addition, when sending a text message, if the number is not selected in the card book but directly entered. In the Sent directory, only the number will be displayed, not the name. If there is no relevant name and number in the calling card before the SMS or backup in the SIM card is copied to the mobile phone, the name cannot be displayed.

Sometimes: a name can only correspond to one number. If this person has two numbers, he must create another business card with different names.

1: A business card cannot have more than two phone numbers;

2. Two different business cards cannot have the same number.

3. The business card in the SIM card cannot be duplicated with the calling card holder, that is, a business card cannot be in the SIM card and the calling card holder at the same time;

4: If the number is prefixed with +86, delete 86.
