There are a few threads already on GPRS (data) roaming in specific countries - but does anybody have a solution which is reasonable worldwide?

I'm starting to use gprs a bit more now that I have a new phone (Nokia 6131) to bluetooth to my Nokia 770 (plus for data-triggered callbacks etc). Main countries I need are Mexico, France, Australia.

Best I've found so far is my old Virgin UK (postpaid) sim which is GBP 5 (nearly $10) per MB - this roams fine on Movistar in Mexico (with Edge speeds even). But that's pretty much it (gt-sim, and presumably most Manx sims, don't roam for data there, although it works in the US).

Are there any other companies, preferably prepaid, that have one flat-rate worldwide for data with excellent roaming agreements? (ignoring perhaps the constantly-changing Italian operators at present!). As this is only occasional use (when I'm out of range of wi-fi) nothing with a monthly fee would work.
