I used micromax data card for a few days in 2016.It was plug and play type.But yet you have to install a numbers of software before it becomes usable.Another draw back is that it frequently lose signal and in main occasions you need to unplug and replug it again to get the signal.P rocessing speed is also very slow.Sometimes it refuse to give you even the minimum 2g speed.Another problem is that it doesnot support BSNL 3g sim.
The product also have heating issue.After 20minutes of continuous use it becomes very hot.I think the product made from material that have low thermal resistance. I will not recommend you Micromax data card.Instead You can go for Airtel, ZTE data card.
THANK YOU
