A few days ago I had to get in touch with Orange Customer Services, in order to enable international roaming on all four of my family's mobile phones. I was needless to say not looking forward to this. However, after a bad start - death by automated menu system, which took over 2½ minutes - I got to speak to a real person, in the UK, who spoke English. Within no time at all, she had done what I'd asked, and even advised me against using mobile data because of the cost, and told me how to turn it off on my particular phone! Excellent.
Also, in my previous post about Orange I had criticised their online system. Well, since it was fixed it has been working fine. My only negative point is regarding their Android app, which is pretty useless (for me) because it will only show details for a single phone. Note: subsequently fixed later in 2012.
