Why didn't my Apple 5 mobile phone text message drop? I mean, all the text messages and sending and receiving numbers will not be dropped in a few days.

Causes and solutions of the above situation:

1. The user may have accidentally hidden the contact. Recovery method:

(1), click the phone icon at the bottom of the mobile phone page, and then click "Group" after entering;

(2), click on the display of all contacts, to see if you accidentally hide the contacts.

2. If not, it may be deleted or system error. Solution:

(1), open the phone settings page and click "icloud" to enter;

(2) Then log in to your Apple ID account. If you are logged in, please push the closed address book away. Just import the backup from the user's icloud into the mobile phone.
