I am literally copying and pasting this question from another user because I am having the same issue.
My daughter has the Just Kids plan, I have Smart Family app to control her contacts & usage. She has many friends that do not have cell phone plans yet & only have email addressses to use their phones with over wifi. The Just Kids plan allows 20 contacts & I put them in with the Smart Family app. The app only allows telephone numbers & will not allow me to put in email addresses of her friends that do not have phone numbers. How can I get those email addresses put in on the APP for trusted contacts? I do not want to go through Settings>Messages>iMessage, since that is already active on her phone.
The message she is receiving when she tries to text the icloud email address is is: Verizon Msg: Your phone has been restricted by the account owner. You cannot send messages until the time of day restriction ends.
I don't have any restrictions on her phone for usage times.
