Bought 4 months ago. I don't want to use it anymore because the 500 Taka package was made limited. You can carry it around and it has a 4-hour battery backup. No hassle of wires, you can connect a CC camera or PC TV if you want. SIM registration is done, only 1 cable and unlimited packages start from 800/1000. There is no date given in any documents saying the company will replace it if it gets damaged. Everything is ok, just recharge and use. I originally bought it for travel, but later the 500 Taka package (60 GB) was made limited, which became a problem for an unemployed person like me to use.
