I am buy this modem 4 year ago. running well without any problem.
nice look. speed 7.2 mbps.
micro sd card slot.
network connection searching fast.
but network speed slow because this is 7.2 mbps modem.
this modem not work in windows 8, windows 10, windows 8.1.
Driver installation with windows 8.1 gives problems. Also the sim card tray in the device is difficult to move. However once installed with sim card the usage is pretty smooth.
Use your mind to it when buying.
