It presents three ports:

umodem0: <F5521gw Mobile Broadband Modem> on usbus1
umodem0: data interface 2, has CM over data, has break
umodem1: <F5521gw Mobile Broadband Data Modem> on usbus1
umodem1: data interface 4, has CM over data, has break
umodem2: <F5521gw Mobile Broadband GPS Port> on usbus1
umodem2: data interface 10, has CM over data, has break

I tried this on all of them:

AT+CPIN=nnnn
