Recently, I bought a 3G HSDPA modem from Cell C (South Africa). it is a ZTE MF190 capable of 7.2Mbps up and 5.76Mbps down.
So anyway i noticed usb_modeswitch does not support it. The details are as follows:
before switching: 19d2:1224 after switching: 19d2:0082
So the question is how to switch this modem? which I will provide as an answer.
