If you both have Apple devices, you can FaceTime. You can set it up as a one-to-
one video call or set up a Group FaceTime with up to 32 people. (Group FaceTime
requires newer devices and an updated iOS; check this site for full requirements.) If your hands are going to be occupied and you’re joining from a phone or iPad, make sure you’ve got something like a stack of books ready to lean your device up against.
Here are instructions for how to set up and join FaceTime and Group FaceTime call.
If anyone in your planned get-together doesn’t have an Apple device, Google Duo is basically an Android version of FaceTime. The app is free to download. Up
to 8 people can join a Duo call. Here are instructions for how to set up and join Google Duo calls for individuals or groups.
