I have a mts mblaze dongle and trust me I really regret to purchase it. Its exactly like throwing ur valuable money in fire. I never recommend u to try mblaze.
Nowadays, the price of high speed internet packs keep decreasing day by day but still mts is providing it in expansive rate. For 1 gb of data, you have to pay more than 250 rs plus u wont get good speed. Mts mplaze is completely a waste product as first you have to purchase mblaze which will cost you around 1.5K plus u have to recharge it with expansive data packs, again and again.
I highly not recommend you to go for mts mblaze, I think you should prefer mobile sims instead of mts mblaze
