Help!!! I deleted all my contacts from my iPhone! How do i get them back?

If you had iCloud enabled then it should have synced them, first of all try turning icloud back on. If this doesn't resync then plug your phone into itunes on your computer and see if they were synced there. If you have another apple divice (iPad, iPod touch) that also uses i cloud see if theywere synced to this, if so then turning on icloud and re syncing should fix your problem.

iCloud could have saved you if you did sync your contacts !!

Try to do via iCloud:

settings>icloud>check to see if your signed in or have contacts on, if you do then turn off contats, keep on phone, turn back on, merge and your contacts should show up again.

Besides, I do like to share you another tutorial recovery iPhone contacts without backup with third-part software, check it here: How to get deleted contacts back from iPhone

Turn iCloud back on. That's where your contacts live. If you turn it off, they vanish from the phone... As you discovered.

Many times the service you have will have them as in, If your Mail service is with G Mail they will be there, if Yahoo the same. Whoever your Mail is with will normally always have them.

Since you turned off iCloud, you can restore contacts from an iTunes backup if having one.

Restore from iTunes: Connect iPhone to the latest version of iTunes, then head to "File" > "Devices" > "Restore from backup..."

Or, directly restore from your device. There's a guide on iFoneTips showing how to restore contacts with or without backups. Hope it helps.
