I'm assuming you have a smartphone. Whenever we're in Europe, I always use 'Tune in Radio' or 'BBC Sounds' apps on my phone. It's also handy if you want to listen in the car - you just bluetooth it to the car stereo. In the stationery van / awning, I bluetooth to a stereo speaker that doubles as a sound bar for the TV. I don't have a massive data allowance on my mobile plane (about 12GB a month I think) and I've never been anywhere near the limit when away (or, probably anywhere near even 25% of it either!). From memory, I think either app uses about 1Mb per minute. Just be careful if your mobile plan only covers you for the EU - in Greece (for example) some parts are very close to Turkey which is outside of the EU and you can get really stung for using a Turkish mobile provider if your phone connects to one instead of a Greek tower (which I found out to my cost but, luckily realised after about 20 minutes!
