Hello friend, I previously bought micromax mmx 210g 3g usb data card. I PURCHASED FROM A LOCAL STORE. I want a data card for my laptop to access internet any where. Company says that speed 14 mbps but inreal world you will never get this speed. I am currently using this data card almost six month and its works well. This is a unlockd data card so can support any simcard for internet access, also have sms and voice calling feature thats I like this modem. This is a good modem.
