The AirTags unboxing videos have started doing the rounds on YouTube, with many reviewers showcasing their initial unboxing and demo clips for the first time. The packaging is simple and minimal; customers either have a choice of picking up a single AirTag or a whole bunch of them, with the 4-pack packaging being slightly taller and bigger, for obvious reasons. The unboxing does not even provide some Apple stickers, only a bunch of documentation and some instructions on how to use them.

When you remove the plastic surrounding the AirTag or AirTags for the first time, they will make a small noise, indicating that they are ready for use. After that, place an iPhone running iOS 14.5 (which will be available later) right next to the AirTag, and just like how the AirPods connect, you will receive a prompt to pair it. Next, you register which item you want the AirTags attached to, then register that tracker to your Apple ID.
