Unquestionably deserving of the cost. It is an excellent choice for use as a 4G modem. No, because USB 2.0 isn't compatible with connecting an external hard disk. As for its advantages, it functions without hiccups and reliably. Work may be done remotely through the application on the phone, and the setup is very convenient overall. There is sufficient coverage over the area. Cons include the fact that the material is of poor quality and that the antennae are easily bent. Does not have any effect on the work.
