You can send and share your location in iOS and iPadOS’ Messages app. Here’s how:
° Open Messages.
° Tap the name of the contact at the top of the conversation. If you’re using iOS 14 or earlier, or iPadOS, tap the Info button .
° Tap Send My Current Location. Your recipient will see your location on the map. Or tap Share My Location. Then choose the length of time that you want to share your location.
(This how-to is based on my experiences and info on Apple’s support pages — where the images sometimes come from.)
