Is there anyone here knows how to unlock a ZTE MF 190 usb modems. I need to unlock my Usb modem badly, because i'm having a very poor internet connection. I need to change my ISP, but buying another locked modem in another ISP is the most very stupid thing to do, practicality speaking. Please help. THANKS
From what I'm reading its usually costly and done remotely. Also many who say they managed to unlock by flashing it have issues after a few weeks.
