12g roaming cap

[Barchy]

Why are we limited to 12g when roaming in EU. How is this 'fair use' who decides the figure? Why are we one of the lowest now. Is it time for me to jump ship and get a better roaming deal?

I think you will find that most networks put a cap on how much data use can use when EU roaming.

I believe that this is linked to the fact that they probably have to pay the hosting network for your usage. I used to be with Giffgaff and they certainly had the same situation.

Good luck finding a better deal jumping ship @Barchy. 
If you do, please share the details here - thank you.
