I tried multiple data cards but I didn’t found any data card who is comparable with any usb supporting router(for example tp link tl mr 3020). and after searching a lot finally I found this beast called Micromax mmx310g who is working for me very well.
I had bsnl EVDO connection but it was really not good if you are using the default evdo card most of time it was not detecting on my computer or its not compatible with windows 7 8 or 10 this data card was only working with windows xp this is the main issue had.
some more issues with the official bsnl evdo data card.
Network issues.
No detection.
Not compatible with latest windows.
Not working with, usb supporting routers.
Micromax mmx310g is able so solve your multiple issue like its really greate device only if you are a BSNL EVDO customer( I am not sure about how it perform with other evdo networks) and its able to get high stregth of network in any location compatable with any windows version and multiple routers.
I am using this data card with my usb supporting router tp link tl mr 3020 and both are working really amazing you won’t need to do anything once you set it up it will automatically connect every time no network issues and now I am able to use internet wireless with the help of router.
These both devices are working very well if you want to create a small internet network without any broadband connection this setup is also very affordable.
