Bought 2 months ago. I don't want to use it because the 500 taka package has been limited. You can carry it with you, it has 4 hours of battery backup. No wire hassle, you can connect CC camera or PC TV if you want. SIM is registered, only 1 cable and unlimited packages starting from 800/1000. There is no date on the documents, but the company says they will replace it if it breaks. Everything is ok, just recharge and use. I bought it mainly for travel, later the 500 taka package (60 GB) was limited, which is a problem for an unemployed person like me.
