I bought MMX 350G and tested it with the airtel 2G SIM. I got a speed of average 5kbps which I found very slow then when I tested the SIM in Nokia E71 I got a speed of 15kbps.
This is really strange as I was getting 3 times more speed with the same SIM in nokia E71 phone. I concluded that MMX 350G receiver reception is 3 times poor compared to E71 receiver.Although its fish design with flexible cable is good as you can use it with your laptop while in bed and your modem will not bend or get damaged.
It can be used as pen drive as it support up 16GB sd card
