Roaming prices are the equivalent of scamming tourists, I don’t think there’s any body that can prevent it internally unfortunately, it’s just somehow acceptable for companies to shake down travelers for stupid amounts of money.
I've read a new clause in an ad that lists the UK as one of these countries, with an asterisk that said only until the date of Brexit (obviously..).
I wonder how much of this was due to ministers being annoyed at having to change SIM cards whenever they landed in Brussels...
