unlock code

[brozer]

can I get a unlock code that I can reuse if modem that I unlocked by dc-unlocker become locked again?
I had found out that modems that are not being used for a long period of time become locked again! I can make a script that determines that modem is locked and will send the AT^CARDLOCK=<unlock code> to unlock it again, but I need the unlock code!

Devices are not relocking after not being used for long time, they can only relock after factory reset or firmware upgrade. If it so happens, that device gets locked again, login with same username/password or dongle that you had unlocked it before and perform unlock again.

I have SIX Huawei EM820U that were being used successfully for a couple of weeks. Then they were disconnected for 5 about month. Now they became locked. All of them.
I use them on a Linux terminal to provide a remote access, so it is not a good solution to go to a place where terminal is installed, remove modems, unlock them and install again.
I can use a COM port sniffer to get the unlock code, but I'd prefer to use correct way, I'm asking about.
