mobile-broadbandnetworkingusb-modemwireless-networking

I just received a ZTE MF667 mobile Internet modem. It has two slots: one for the SIM card and one for a microSD card. Is the microSD card required? What is it used for? Is it required for the Internet connection or just a feature so that I can store data on it?

  • Does the microSD card required?

    No.

    What is it used for? Is it required for the Internet connection or just a feature so I can store data on it?

    Yes, exactly!

    [EDITED] Just a feature to store data on it, not required for connection. Every USB - Modem has a small Flash memory to store the driver needed for Windows / MacOS installation. That is why the microSD slot is not "needed" at all and is just a feature ...
