I have purchased MTS Mblaze( Huawei EC 306) for my personal use couple of months ago. What I thought was, it would be handy for me to carry a dongle for highspeed internet service. Here are some views:
Advantage:
Speed is quite good. Speedtest gives 10-15 mbps
I have not faced any connection problem.
Disadvantage:
Price is too high. You can use your 4G internet in the same price.
Why use a dongle when we get high speed internet in same or low price in our mobile phone.
Its data calculator differs with server's data calculator.
Suggestion:
I would suggest not to go with MTS dongle. In case u need it then use prepaid only.
