Check your iPhone & iPad IMEI number to verify Apple coverage, activation status, warranty expiration date, AppleCare eligibility and status. Make sure the iPhone is original and not fake, not replaced, still under Apple warranty, doesn't have iCloud lock, clean and has not been reported as lost/stolen. Our online tool is especially helpful before buying or selling a used iPhone.
