Okay, one of two childrens phone is HTC One m8s. HTC uses "people" app for contacts. Norton family has allowed contacts (6pcs) to call even the device is locked either for over consumed usage time or time table restriction. Well for this HTC model the people app is blocked by norton family like this similarly to this post. I have no time to get back to Norton support second time to resolve this, after 1st try and hour spent with the Norton mobile teams the resolution was to re-install family. Did it, didn't fix it.
One way to go around this is to make (atleast in htc) a shortcut/launcher to phones "desktop" for direct call to "whitelisted" persons. When you make the call, the norton family pop ups but the call goes through.
@ Norton, you might wan't to resolve the issue with htc ones people app..
