I know there are issues with Web Guard at the moment with the latest update and resent iOS for iPhones. Just to let anyone know from Trend Micro and the community that I have been resetting my phone and I will get internet activity for around 2 minutes then it will stop again after that. There is data being downloaded after the stop to internet and app activity but where it is going I’m not sure. 
This issue is only whilst using Telstra and not wifi.
