you may not
I tried that with Sky that with Sky go
It detected i was on a IP outside the UK and stopped me viewing
So assume BT are already ahead of you and will be blocking viewing
I'm abroad at the moment and can't get BT Sport. Or live UK TV streams of any kind. Or online catch-up services. Or today's Daily Mail. Or baked beans and tomato ketchup. There's no Sainsburys. The Royal Mail aren't bringing me my letters. Some people can't understand English. And they drive on the wrong side of the road. And I love it.
