@Ashok,
 
Just to confirm to you that I'm not making stuff up. Please review this thread that the Orange EVDO modem not working across all flavours. I also do not see any of your responses to this thread below. I see that it talks about the different versions that the modem works on and others that does not. Also mention where the problem is, whether the kernels need updates etc,
