Sierra Wireless AC875 cannot unlock

[scorpiosez]

I have a Sierra Wireless AC875 PCMCIA card that was a part of a pile of computer stuff I won on eBay. The card was provided and is badged as Big Pond (Australia). There is a sim card inserted, and the card does detect in Windows Device Manager on my XP Pro SP3 laptop, and also in the dc-unlocker program. The latest firmware was already installed, and the BigPond connection Manager detects the modem as not yet registered. Below is the response to the auto-detect by dc-unlocker

When you remove the sim card, the modem does not detect in the dc-unlocker or in the Windows Device Manager.

How do I unlock the card without the sim inserted, if the card is only detected with the sim inserted??

Could you try to unpdate drivers from dc-unlocker folder? It may be drivers problem that dc-unlocker can not detect it.
