Samsung GT-B3740 4G LTE Modem
First of all, this USB modem is not for everyone. If you live in an area which doesn't have LTE coverage, then don't get these LTE modems. You won't be able to use this device without LTE connectivity because, like other LTE devices, it is not backward compatible with older technologies. That being said, let us now move on to the merits of this wonderful device.
