BSNL MMX300G 3G Usb Modem is a very good Modem . But the speed may differ in different places because of the Network problems.

* Double check (UMTS) 3G is available in your place .
One Tweak which you can try if you are using Windows XP is (similar steps for VISTA - but you will have to navigate your way through) :

Go To My computer >> Control Panel >> System >> Hardware >> Device Manager >> Expand Modems section >> Select the 3G USB Modem installed >> Right Click for Properties >> Modem Tab >> Note down the Port Number following Port: COM? (Lets say COM5 for now.) Close the Modem properties Dialog Box.

Now Expand Ports (Com & LPT) section:
Select the Communications Port (COM5 as in our case)>> Right Click for Properties >> Port Settings tab >> Bits per second >> Increase it to the highest possible value (128000 in my case).

Close all Dialog Boxes. This setting should take immediate effect without any restart.
