How to get password for AT commands? (EM7421)

Is it usually written on the manual for example your laptop?

you can try

AT!ENTERCND=“A710”

is this new module from Sierra factory?
Has someone changed the password before?

I never even installed the drivers since I bought this Fujitsu Laptop. Just found out, never changed anything. It was bought new from a Fujitsu Reseller.

others user do not find problem on this command on EM7421:

no idea, maybe someone changed the password before

the device is new. but i will contact fujitsu. thx
