I have bought 3G usb stick since 5-6 months before. Since I purchased this USB stick. It is not working properly. Always network problem. Frequent disconnection problem. I have online business and this type of worst 3G service affect my business.
Unfortunately, I have to use it for 6 months because I have recharged of Rs.4250 for 6 months. This is the mistake I did by seeing that good advertise of zoozoo flying. I have also complain to their customer care many time. The give resolution time of 15 days. Working like Government department.
