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. Below are some advantages: It continues to function without any issues. Work may be done remotely through the application on the phone, and the setup is very convenient overall. It provides a good coverage area. Cons: The material is of poor quality, and the antennae are somewhat fragile. Does not have any effect on the work.
