How to Enable Airdrop on iPhone or iPad

Swipe up from the bottom of the home screen. This opens the Control Center.

Tap and hold one of the connectivity icons. You can tap and hold Wi-Fi (three curved lines), Bluetooth (a sideways bowtie), or data (the antenna). A list of connectivity options will appear.

Tap AirDrop. It looks like a spiral with a triangular chunk missing from its bottom.

Tap Contacts Only or Everyone. Choose Contacts Only to share files only with your contacts, or Everyone to share with people you haven't yet added. To disable AirDrop, tap Receiving Off.
