My son just got his first phone and I've set it up with parental controls. However this means he can't have WhatsApp, so can't join the group family chat which he wants to do (to message aunties uncles and grandparents). Is there a way to keep safety filters on but allow WhatsApp? It is there another free messaging service we could all get. I know WhatsApp is classed as social media but he doesn't want to talk to anyone other than his family!
