Hi all. I had problems where my Orange contract hero couldn't connect to the new Orange T-Mobile service, so they sent me out a new SIM. Now, when I manually try to connect to orange t-mobile, it says "can't connect because data roaming is disabled". I'm not really sure what the implications are of this... whenever I turn this on I get warned I could get charged, and most advice I've searched for says to keep it off. Do I have to have this on to connect to orange t-mobile, and is it safe to do so?
