I cannot install AirTag
I can't install AirTag on my iPhone
Question marked as
Hi! When you take the AirTag out of the packaging and remove the plastic wrapper on it, it should chime and be noticed by your iPhone and a pop up should appear, allowing you to set it up. If the chime is not occurring, remove the back of the AirTag and take the battery out and put it back in, then put the back of the AirTag back on. This should reset it, and the chime should hopefully start. Follow the attached guides below for more details. Best of luck!
