How Do I Delete People From My Messenger

Messenger continuously syncs contacts from your phone. If you want, you can turn syncing off.

Anyway, you can remove your non-Facebook friend contacts very easily. Follow these steps:

1. Tap People
2. Tap Info against the person you want to remove
3. Now Remove Contact

If your synced contact list is too long to manage, you can remove them altogether from Facebook.

Try following these steps:

1. Go to https://www.facebook.com/mobile/messenger/contacts
2. Now Delete All

Then log out from Messenger app and log in again. Hope you won’t see them anymore.
