A few simple ways how you can throw attempts to enter NCK code in some modems Huawei, screened for E1550, E1750, E173, this method works 100%.

AT^CARDUNLOCK="nck md5 hash"
Counter attempts to enter the unlock code to reset the value of 10 (10 times you can re-enter NCK)

You can now directly through the terminal to enter the unlock code itself Modem AT^CARDLOCK="nck code"

Get the key can unlock Huawei modems by NCK

Check the lock status and attempts left with the command

AT^CARDLOCK?

modem will give the answer, for example

AT^CARDLOCK?
^CARDLOCK: 2,10,0

The first digit -> 2 - means that the SIM Lock is cleared or not, 1 - indicates that the modem is locked.
The second digit -> number of tries remaining unlock code. By default, the new modem to 10 (sometimes new modems over the counter that do not attempt, as conceived by the operator, but also can unlock;)

We remind that all operations should be performed without a memory card and SIM card in the modem, so reliable.

A small addition to the different types of GSM networks:

at ^ hspa = 0 - wcdma
at ^ hspa = 2 - hspa-mode
at ^ hspa = 1 - hsdpa
at ^ hspa = 3 - hspa + mode
