I've just been informed both by o2 and 3 that they do not support Pay as You Go (or contract) Data Roaming for iPads. So if abroad and you need to access the internet for flight planning, and no WiFi is available, what do you do?

Buying separate SIMs for each country does not seem to be a viable solution either.

I realise this is an Apple not SD problem but it does seriously inhibit the use of SD on the iPad for touring abraod.

What Vodafone and O2 told you is a crock of bull. I use data roaming all the time. I have an Austrian A1 contract and buy roaming packages add ons as needed when I go abroad. They are about 15 EUR for 250 MB, IIRC.
