Having had uninterrupted access to BBC iPlayer and also watching free Filmon for a long time . Things are changing .
Obviously the best way to still see BBC iPlayer and have access to other stuff from around the world is to install a VPN. Lots of options free and subscription.
I tried lots of the free ones and they are unsecure and unreliable...did all the research and the best value for money at the moment is NordVPN......there is a special offer which is $79 for two years http://nordvpn.vpn-coupons.com/ scroll doen to see the offer.
I can now see what I want including access to my son's Amazon prime video account in the UK . The security is very good .
The free version of Filmon is now full of adds and switches off frequently .
A lot of reviews e.g. https://www.vpnmentor.com/reviews/nordvpn/
