Lenovo ThinkPad EM7455 4G LTE Mobile Broadband (4XC0M95181)

The headline says it.

I checked carefully, I went to the documents and Lenovo website, copied the FRU number, searched Amazon. Ended up on this card. The laptop tells me that an improper network card is installed, system halted. This is the second one, so I give up, no LTE for me. 3 Stars because the card works in a dell, but two because the card doesn't work in my laptop, despite the same part number.

Great product! Easy to install, never had and issue!

Tested on Thinkpad P51: - Works on Windows 10 out of the box. - Linux kernel 4.17 or more is required, after that, wait for network registration (a notification should show up), and connect to your APN. Edit (July 2019): Sounds like 4.17 has some troubles with the hardware. It is most of the time required to restart the NetworkManager and ModemManager, or even to completely reboot to make it work. However, upgrading kernel to 5.0 seemed to have fixed all the problems (still works after suspend, weeks uptime, etc)

Does the job. This particular revision is required for the X270. Other EM7455 cared are not compatible (same model, different revision).
