How to recover lost contacts on iPhone 5s
Before playing the trump card, I'd like to introduce two tricks to recover lost contacts on iPhone 5s.
Trick 1: Save lost contacts through iPhone messages app
Within this trick, you can recover some lost contacts you frequently use in daily life.
a. Run the iPhone message app and create a new message. Type the name of the contact you wish to save and the name will appear as a drop-down suggestion as long as you contacted the person before. Then tap the "i" symbol to the right of the auto-suggested entry.
