Hello kuromi112,
To help us get a better understanding of the issue, we’d like to ask a few questions.
1. Is this happening with multiple contacts, or only a certain one?
2. Are you experiencing any issues receiving calls or messages?
If you are experiencing issues making or receiving calls, please check out this link, which has information that may help: If you can't make or receive calls on your iPhone
You might not be able to make or receive calls on your iPhone if you have certain settings turned on, if your software isn't up to date, or if there's a problem with your network.
For information on sharing your location from iMessage, please check out this link, which may help as well: Share or stop sharing your location
You can stop sharing your location with a particular person by choosing that person in the People tab, then scrolling down and choosing Stop Sharing My Location. Or you can stop sharing with everyone by turning off Share My Location in the Me tab.
If the Find My app has been deleted from your device, you can turn off Location Services (go to Settings > Privacy > Location Services) to ensure your location isn’t being shared, then download the Find My app from the App Store again.
Important: If you initially shared your location from iMessage rather than Find My and stop sharing, the person you stop sharing with may receive a banner in iMessage that you’ve stopped sharing your location. If you began sharing from Find My, and then stop sharing your location through Find My the person won’t be able to see you on their list of friends. If you reenable sharing, they get a notification that you’ve started sharing your location with them.
Thanks!
