I purchased this data card 2 months back, its paid ahead of time. Max speed accomplished 350 kbps in city limit(Company guarantees upto 6.2Mbps) Very irritating stuff is they used to change the arrangement all the time.
For example, When I got the device, I paid 999 for 20GB after that it was 1250 for 20GB and today when I am going to energize it indicates 5GB for 999.
Note: Worst arranges and data card ever. I wont recommend this gadget to anybody, even to my enemy, contrast with TATA MAX WIFI there are parcel of good gadgets out in business sector.
