TV Box abroad?

Hello

I have a technical question about your NET + TV Box (NOT Sat!).

I wanted to know if I take a NET/TV/Voz subscription, may I also use the TV Box abroad part of the time (in Luxembourg)?

I’m asking this because we generally are 3 months/year in Portugal, the rest of the year we live in Luxembourg. It would be handy to have TV in Portugal with your TV box during those 3 months and taking the TV box with us to Luxembourg the rest of the year, in order to have Portguese TV there with your box.

Is your TV Box blocked to NOS internet subscription line (is it checking the internet IP before connecting to the IP TV service)?

Thank you for your response.
