I spoke at the Future of Mobile conference recently and stated silly mobile tariffs were holding us back as an industry. And they are silly. They're complicated, there are too many of them, there's lots of very small print (which I can't read even *with* my glasses on), extra roaming charges on a per megabyte basis (who knows what a megabyte is anyway and how do you know the size of a page *before* you click on it?) and well, they're just so unnecessary.
And if you don't believe me, go take a look at MobileMeg who has attempted to collate all UK mobile data tariffs (albeit I suspect it's a little out of date as I know Tesco has recently introduced a new mobile data tariff - yet another one!). It's not pretty and it's not clever. Network operators - sort it out! Complexity is not a good thing.
