How do i configure huawei usb modem
I can't say for your model and/or place, but I have tested these Modems 3G Huawei which are listed in the Telcel Mexican Broadband ISP and everyone is working right out of the box. There is simply a procedure that should be done in order to use it as modem, because of the dongle installs initially as a CD-ROM Drive, which shifts to Modem mode when ejecting.

A screenshot of the modems is placed here for your convenience.
Good luck!
