I have tried Tata Docomo 2G Plan, Rs.95 for 4GB/30 days validity. It is working fine giving upto 20 kbps (avg). Uninor offering 2G data plans starting from Rs.9. I was unable to connect through Uninor customer care executive answered that they support only through mobiles but not for 2G data cards.

    I am from Bangalore. Yesterday I bought D-Link 3G USB Adapter(Model No:DWM-156) and I recharged DoCoMo for 2G .After that I tried to connect through D-Link connection Manager but its not connecting and also the entire system will be stuck. Then I contacted D-Link executive, as per his direction I did the settings, but same result .While using D-Link, three times I forced to shut down my lap top as there was no other way for me. Please give me one solution for the same . I tired with access no:**99***1# but its does not work :(. I had seen your settings documents. As per the documents i did the settings,after that when i press the “Connect ” button the entire system will stuck :(

      Rakesh virus effected systems or low configuration systems may struck. If you doesn’t have these problems, once unstall Dlink software and again install and try to use USB Extender and place data card in full signal receiving mode.

  2. Musharraf ansari says:

    Rakesh i think that you tried to manual setting for configure your usb modem like that ..
    For Tata docomo …For acces point type– ” TATA.DOCOMO.INTERNET” and access number is *99# or *99**1*1#
    For Airtel Acces point — airtelgprs.com and oter thing same as avobe
