I purchased this data card a year ago and using it without any issue. But the speed is too slow only 7.2 Mbps which very less compared to other dongles available in the market.
This data card is not supported with Windows 8.1 and above Operating System and if you want to use it with above mentioned OS. then you have install two extra drives which is available in C:\ProgramFile(X86)\MMX353G 3G USB Manager\Driver\Win7_64\cmnsmdm and cmnsser. Right click on the both driver and install it and enjoy the internet. This dongle is not suitable for the workers who want high speed internet while working because it have only 7.2 Mbps speed.
Good: Easy to use
Bad: Sometimes stops working, hang issue, Lost of connection, very low speed, Not suitable for higher version of windows OS if you do not install extra drivers which is0 mentioned above, Boring user-interface.
