I was in Croatia (from Slovenia, the nighbour country) for two weeks and I used cca 24GB(!!!) of data and was still left with 6GB unused. For €11 (eleven Euros)!
I'm also "in this business" for more than 30 years (counting the learning years from when I was 7) and I can only say: "Yup!"
I'm paying those 10€ for the Home plan at this moment!
