Hi jeancarlosff,

Warm Greetings & welcome to Lenovo Community, happy to have you here.

 

Sierra Wireless EM7455 is compatible with ThinkPad X270 but the FRU #00JT547 that you have posted will not work with your system, as BIOS is whitelisted. 

So compatible WWAN card will be 01AX746 also you need to check whether your system is WWAN ready or not.

 

I hope the above information helped you.

Please feel free to post in Lenovo Community Forums if you have any further queries!

 

Regards,
Prabhansh

Let me explain.

BIOS (its whitelist for wireless devices) isn't a cause of possible issue of incompatibility as all em7455 modems with Lenovo FRU have the same hardware IDs.

Modems have different revisions. According to my tests and the forum cases, new ThinkPads, Kaby Lake generation, don't support old modem revision, TC' modem is one of them. Most likely the laptop will not recognized it as it should, no matter what is the OS.

In addition to the compatible FRU 01AX746, there is another FRU - 01AX748, as it's a substitution of the first one.
