Find My Friends: Notification issues
If you can’t set a notification
You or your friend might be using a device that doesn’t support location notifications.
You can set a notification on a device with iOS 5 or later, however, the person you’re creating the notification for needs to have iPhone 4 or later, iPad 3rd generation or later, or iPod touch 5th generation with iOS 6 or later.
You can’t set a notification for anyone who is using iPhone 3GS, iPad 2, or iPod touch 4th generation.
If you’re not receiving notifications
Your friend might be in a location with poor cellular coverage. Also, make sure your friend:
Has Find My Friends turned on in Location Services (Settings > Privacy > Location Services).
Has turned on Wi-Fi in Settings.
If friends aren’t receiving notifications
You might be in a location with poor cellular coverage. Also, make sure you:
Haven’t stopped sharing your location (in the Me pane).
Have Find My Friends turned on in Location Services (Settings > Privacy > Location Services). If Find My Friends is dimmed, check Settings > Restrictions to see if the restrictions need to be changed. If not, contact the person who controls the device’s restrictions.
Have turned on Wi-Fi in Settings.
If friends aren’t seeing the name they expect in notifications from you
When you send notifications, the name that your friends see is the one that’s associated with your Apple ID. You can check or change your name on the My Apple ID website.
Tap Manage your Apple ID, then sign in with the Apple ID you use with Find My Friends.
Check or change your name in the Name, ID and Email Addresses section.
