Worked out perfectly fine for me. My provider is one of the cheapest available in Austria and they recently sent me a message to let me know that I now pay the same for phone calls and mobile internet in other EU countries.
Of course it is a problem. I pay for 10gb a month but go on holiday for say two weeks and only have 2gb available precisely when I'm likely to need most of my allowance. I get charged a ridiculous rate for each GB after that. This is a big improvement but is not the end of roaming as it is currently advertised.
