If you're walking in an isolated area (I often walk my dog in a large remote field) and someone approaches you or comes to attack you and you're in danger, is it better to call 999 or a contact like your DH or parents? I'm just thinking if you can't outrun them or get away or they grab your phone, surely 999 wouldn't do anything if it got disconnected whereas an emergency contact might realise somethings wrong but then if they don't pick up maybe 999 is better?
