New data-roaming offer by Wind Italy

[Bossman]

Okay, I just learnt something new. So, there actually has to be 3G agreement, and not just data agreement for foreign sims to roam on 3G if available. My Virgin UK sim roams on AT&T's 3G here without any problems. So does a friend's Tmobile UK sim. You would think as long as a phone has the appropriate bands and there is data agreement, it should be able to use data, 3G or not.

I can tell you for sure that in the USA it doesn't work on AT&T's 3G net, but surely you have 3G in UK, Germany, Switzerland, Austria, Spain, Portugal and probably many more...

no, the agreements for GSM and 3G are negociated seperately.
