T400 and WWAN cards

Dear All,
Dear Zender,

I have Lenovo T400 (2765 22G) with the SIM module ready, I bought new OPTION GTM-378E WWAN 3G card unlocked.
After rebooting I got error 1804 and the system is unable to work unless I uninstall the new card.

After searching online, I found that it is something related to Lenovo, and that only cards from Lenovo are accepted.
Is there any way to bypass this BIOS protection ?

Please advice :?:

This subject is extensively covered in the the T6X forum: T6x BIOS device whitelist (error 1802/1804)[solved] - well worth a read. :thumbs-UP:
