Airdrop users on ipads
I am new to the Apple iPads, and a senior. Can anyone tell me if airdrop only works in your own home, that is to share files, videos, and pictures between lets say your iPhone , iPads, or your apple desktop, or perhaps you have others visiting with apple devices, and they want to receive the airdrop information as well.
What I was hoping to do was to send a large number of photos, and the occasional video to my sister, who lives in a small town approx. 35 miles from us. She too has an ipad, and we have, I believe our settings set up properly. Blue tooth, and Wifi turned on, and receiving from anyone. I appreciate any help.
Thank you.
