I have been using this data card for nearly 8 months, but what I had experienced is horrible, it’s just horrible, I never receive the full network on this device, even at the same time I was receiving the full network of the same sim in my phone, I bought it for ₹1, 799, which is totally wasted, please anyone who is planning to buy this USB card, please dont go with it, you will hate it from the first day, due to its low network, I had never received high speed internet, the maximum speed it went in my whole experience was approx 280 kbps, but in the description it shows 21 MBPS, please guys don’t buy this product, I strictly don’t recommend it. It’s service centre is also very much poor, I thought there is some defect in the device so I tried to contact the company, but no one responded me for this, please guys don’t buy it.
