I subscribed to Roaming No Limit while in Greece. (It didn't work with Cosmote - see Greece HSPA thread.) Returning through Italy I sent a 'Roaming No Limit No' SMS which was rejected: 'invalid text'.

Now back in the UK I looked at my account and found that Roaming No Limit already had a Deactivation Date one month after activation. I also found this:

L'opzione ha validitÃ* mensile e NON si rinnova automaticamente.

So it seems this one works differently from the others.
