A, mobile phone contacts do not display processing method:
1, check the phone settings.
You can check whether the "SIM card" contact is checked in the following ways.
OriginOS mode: Enter Settings-Applications and Permissions-System Application Settings-Contacts-Sub-account Display-Check "Mobile Phone" Contacts;
Funtouch OS 10 model: Go to Settings-Applications and Permissions-System Application Settings-Contacts-Show Contacts, and check the "SIM card" contact;
Funtouch OS 9 model: Go to Settings-System Application Settings-Contacts-Select the contacts to be displayed, and check "SIM card" contacts;
Funtouch OS 3.0-4.5 models: Go to Settings-Contacts-Select the contacts to be displayed, and check the "SIM card" contacts;
2. Check whether there is a vivo account login on other mobile phones. If more than one mobile phone logs in with a vivo account and the "Contacts" synchronization switch is turned on, when other mobile phones add/delete contacts, all the mobile phones logged in with this account will be synchronized. It is recommended that you enter the cloud service and restore the contact information in the recycle bin; At the same time, on other mobile phones, cancel the vivo account before using it;
3. If you have backup contacts in the cloud service, you can go to Cloud Service-Settings-Contacts and select "Smart Merge Contacts", and the contacts will be synchronized from the cloud to the mobile phone;
If the above methods are not improved, you can go to vivo official website /vivo Mall APP-My-Online Customer Service-Manual Customer Service for detailed consultation.

2. Restart the phone;
3. Put the SIM card into another mobile phone, or put other SIM cards into your own mobile phone for comparative test to determine whether it is a SIM card problem or a mobile phone problem. If the SIM card is damaged, I suggest you change it in the operator's business hall.
