If there's an issue when you send a gift

• The recipient of your gift must have an Apple ID in your country or region. For example, if you're in the United States, you can't send a gift to a friend who lives in Australia.
• In some regions, you can't send gifts. Store availability also varies by country or region. Find out what's available in your country or region.
• If you use Family Sharing and Ask To Buy is turned on for your account, you can't purchase gifts. 
• You can't gift individual songs on an iPhone or iPad. To send a song as a gift, use your Mac or PC.
• You can't send apps, TV programmes or films as a gift on a Mac or PC. To gift those items, use an iPhone or iPad.
• You can't send a free app or item as a gift. But you can tap the Share button  or the arrow button  to share a link to the app or item.
