What I'd like to see investigated is the home data rates operators charge.
How on earth can they justify the £2 or £3 per Mb rates just for UK? !! (looking at you Orange!).
Daily caps are okay apart from the likes of Orange ignore your request to be put on such a rate and worse by default they sting you for £3 per Mb or more if you don't set a rate.
On the roaming front though, caps on the extra charge are good, but the operators own daily caps are not applied when roaming, so when you pay a flat £1 per day or whatever in the UK, you could be back to paying archaic "per Mb" rates abroad.
And of course none of these caps apply out side the EU.
£8 per Mb for US data Orange say? No chance mate! Thankfully I have WiFi on the phone, and at least in the US I can find free or cheap hotspots in cafes, hotels and major cities, unlike most of the "fleece the customer" operator run hotspots in the UK.
