There are a few possible explanations for why your contacts might have disappeared on your iPhone. One possibility is that you may have accidentally deleted them.

If they’re not, you can try using a backup app or transferring your contacts manually. If all else fails, you can try restoring your phone to its factory settings.

If you have an iPhone and your contacts are not on iCloud, then they are most likely on your device only. To get them back, you can either restore from a backup or sync with iTunes.

There is no one definitive answer to this question. Some people prefer to save contacts to their SIM cards, as this can make it easier to transfer contacts between devices.

Ultimately, it is up to the individual user to decide which method works best for them.
