I have just received this from Voxi. I have been in France one week:
"Hello. Just to let you know, we're making an important change to how you use your phone while you're abroad. From 27th May 2022, you'll need to purchase one of our new European Roaming Passes to use your plan in our European Roaming Zones. These are available from £2 a day, or £1 a day if you purchase an 8 or 15 day pass. A fair use policy of 20GB applies to data while roaming. For more info about this change, and our new European Roaming Passes, please visit https://help.voxi.co.uk/1787185942"
