     The first time I used it was in China in April.  I thought something was wrong with my setup.
     After an hours contacted their CS.  Turns out that about 2 hours or so later it was working - before I got a response.   It worked fine after that and always logged on right away when ever I turned on the phone.  To save themselves CS time - they should warn people it might take up to 3 hours, in some countries, to log on for the first time.   Their rates in most countries are VERY competitive.
