Airtel Micromax MMX 350G is very slower internet provider data card.Even I used this data card last 1 years.But it is a bad experience for me because its internet service is very slow and gives poor signal.It supports 3G network signal.But its slower internet speed like download and upload speed is within 200 kbps.Sometimes the internet connectivity break due to its technical issues.The customer service is very bad.The main problem of this product is slower internet speed and connectivity problem.
