I just bought BSNL 3G connection a few days back .I am using it with Huawei E1750 USB modem for browsing internet on my laptop.Initially I was getting just 1 bar where the signal is showing on the USB modem software.I attached the USB modem to a USB extension cable and relocated it just 2 feet away from the laptop.Interestingly now I am getting 3 to 4 bars or even 5 bars sometimes which keep changing from HSDPA to WCDMA and vice versa but a constant Blue LED is observed.But I have still not been able to experience speeds more than 1.5 Mpbs(download).More such tips for mutual benefit would be welcome
