Once the setting has been finalized, you will be able to spot other Apple devices that are within range, and you can start sharing your files with them.
The best part about Airdrop is that there is no limit to the size of the file you can send via this service. Apple has not mentioned a top limit, so as long as the two devices are in range, you can send absolutely anything via Airdrop, and depending on the size, the transfer time will be determined.
Please note – Airdrop is only compatible with Apple devices, and as such, cannot be used to transfer files between an Apple and Android device.
