T470P WWAN card support

I have a T470P laptop. I wanted to upgrade it with a WWAN card. Checked the supported devices and bought the Sierra Wireless EM7455. I installed the card and I got the 1802 unauthorized network error on boot up. Check this forum and I can see that there is a FRU number and that is important to be compatible.

This is out of my mind how it is possible that this important information is not written at the supported cards. Now I have a EM4755 card with newer FRU number that is supported and I can not use this.

 

Is it possible to update the supported card list in the bios or some other trick to use my stuff?

 

Thanks a lot

Re: T470P WWAN card support

Welcome to the Community

Approved wwan cards and their marketing p/n or FRU # are listed in multiple Lenovo sources:
- on-line stores http://accsmartfind.lenovo.com
http://www.lenovoquickpick.com
- system service parts file
https://pcsupport.lenovo.com/us/en/solutions/PD104722
- the parts lookup service on the support site

Anyway, I agree, some information might be outdated or not full.

what do you mean?

> Now I have a EM4755 card with newer FRU number that is supported and I can not use this.

what's the card's p/n or FRU #?

Re: T470P WWAN card support

Dear x220forme,

 

 the details of my card:

 

 FRU PN: 00JT547

 Lenovo PN: SW10H24567

 

 Attached a screenshot from the card.

 

 Is it possible to update the whitelist of the BIOS somehow?

 

Thanks a lot!

 

Best Regards,

Gabor

Re: T470P WWAN card support

Not a white list causes issue you've faced. All Lenovo branded modems em7455 with different p/ns have the same IDs - USB\VID_1199&PID_9079. The difference of the wwan modems for SkyLake (x60) and KabyLake (x70) based ThinkPads is their revisions, as well as some settings stored in the NVRAM. The card you have is for x60 ThinkPads family. Even more, presently it's positioned for MIIX-710-12IKB only.
