What should I do if my original information and contacts are gone after changing my mobile phone?

What if all the contacts on the mobile phone card are gone? How to deal with the short message or contact loss of mobile phone in vivo;

1. If the SIM card is replaced, the lost information and contacts may be saved on the SIM card. After changing the card, the messages and contacts in the SIM card will not be able to be viewed in the mobile phone;

2. Enter the phone settings (system application settings)-Contacts-check to show the contacts in the phone and SIM card. If unchecked, the contact will not be displayed;

3. If you used the cloud service to back up contacts or text messages before, you can enter the cloud service to restore the backup; If it has been backed up by a third-party software, it can also be used to restore the backup; If there is no backup, it cannot be retrieved.

It is recommended that you often back up important materials to avoid data loss. Reason to speculate:

1.

The Sim card is damaged.

2.

It's not that the contacts on the sim card are gone, but that when the contacts are initially stored, some contacts choose the path instead of the sim card, but the mobile phone memory.

Solution:

1.

Generally speaking, the sim card will not only lose data, but also be unusable if it is broken under normal circumstances. Assuming that the data is lost, we can only seek a solution to the sim card problem from the business hall of the local operator.

2.

If some contacts are not on the SIM card from the beginning, you can try to plug the SIM card back into the original phone. Assuming that it is completely displayed, some contacts are still on the original mobile phone. If you still lose contact, refer to the first one. The quickest way is to use address book-like number storage software, such as "xx address book", which can be downloaded and recorded on the original mobile phone, and then the address book can be overwritten on the new mobile phone.
