I have a Tata DOCOMO 3g usb modem (MF631- manufactured by ZTE) which works fine on on Mac or Windows based laptop/desktop. 1) When I use this on Adam by connecting on the USB port, it is not recognized and nothing happens. The light on the modem shows blue. I have hunted for any generic driver in the web but could not find any. Is there any good driver that will work for this? 2) I removed the SIM card from this modem and inserted in the SIM slot of Adam. The SIM is recognized, signal strength bars are shown but the E or 3g signal icon is not visible. Even though I am able to send SMS, I am not able to browse the internet. I had set the APN parameters as recommended by the ISP. (BTW, I have a 3G enabled SIM from the same ISP on my Nexus One phone which works fine on Adam). I suspect some minor setting should make the modem sim work. Can any one throw some light on this please? Even though I have contacted the ISP's support they do not appear to be competent and Adam is new to them (India). Any help is appreciated!
