I have had no end of problems with this sim. Yes - when it works it is good.... However every time they bring out a MUST HAVE update it stops working. I have had to pay twice.... I bought the Premium version - then after about three or four crashes it failed to ever work again. So I bought the standard version. Each time my internet supplier told me I had used up my monthly allocation... Then that basic version failed.. And the Jabiru that I paid for was gone.... That was last year. Now we have upload 5 and it is happening again. Nothing works. Worst program EVER!
