Is your iPhone covered by AppleCare+?
If you have an AppleCare+ plan, you can use it to cover screen repair. AppleCare+ gives you expert technical support and hardware coverage from Apple, including accidental damage protection. Each incident of accidental damage is subject to a service fee or deductible, depending on your plan. If you don't have an AppleCare+ plan, you'll pay the out-of-warranty fee.
If your device is covered by AppleCare+ and you request onsite service, the additional onsite visit fee will be waived.
