David Meyer at ZDnet has some interesting comments on Orange UK shooting itself in the foot with a supposed "flatrate" tariff at £8 / month which it's capped at 30MB. Which is the same cap that T-Mobile offered about 15 months ago on Web'n'Walk - mostly over 2G devices at the time - for a broadly comparable price.
Funny, I could have sworn the intervening period has had several HSDPA launches, and much faster ramp-up of WCDMA, which vastly reduce the cost-per-MB to deliver Internet access.
30MB is fine for email & some very limited WAP & HTML browsing. I know, as I've got that pre-flatrate Web'n'Walk tariff and 2G device I use for that purpose. But it's not useful for any decent usage of a decent browser on a decent phone with a decent connection - I got hit with substantial over-use charges when I swapped the SIM into a 3G Nokia with a good browser for a month.
I hate to think what the roaming charges are.
