I have 6s and she has 5c. Maybe this is the problem. Still, not seeing photo
Are you both on the same OS? Try on "contacts only". Make sure you each have the other's Apple ID email in the contact cards. Review the list I posted above. It doesn't matter you have different phones. Be sure wifi and Bluetooth are on in both devices.
Here's more tips:
•Sign out of iCloud on your devices and then sign back in
•Restart your iOS devices
•Force restart an iOS device by holding the Sleep/Wake and Home button
•Restart your Wi-Fi router
•Disable and re-enable Wi-Fi and then*Bluetooth
•Enter Airplane Mode on an iOS device for 30 seconds, then exit
•Sometimes disabling and then re-enabling iCloud Drive seems to*do the trick
•Don’t use uppercase characters in your Apple ID login
•Toggle Bluetooth off and then back on again
•Update both to iOS 10.3.1
•And the*mother of all iOS troubleshooting tips—reinstall iOS.
