We did not sign up to the agreement that would allow Sky to transmit from a U.K. subscription via the internet outside of the U.K. and Ireland. We have also not signed up to the current data roaming agreement which means that prior to the 01/01/2021 you could use the 4G anywhere in the EU as if you were in the U.K. The companies are no longer bound by these restrictions and are starting to impose stand alone charges for U.K. users in the eu. I believe some have started already with the majority to follow on the 01/01/2022. If you travel to the EU and you pay the bill turn off your data roaming until it is required then shut it down again.

For balance you do have a duty free allowance but the prices do not appear to be that much cheaper. I don’t want to derail the thread but you also now need to remember we are the all others gate at passport control, and the nothing to declare at customs (if you don’t of course. I would not suggest going through the EU gates if they are separate, because they are likely to send you back or search your luggage. We are now classed as a third party country (I believe that what it is called ).
