Hello all, thanks in advance
i bought the yoga x1 recently without the wwan. Now I want to add the card but note there are two available on the website
em7355 and em7455.
Have searched by can't definitively figure out which one goes with 2016 yogax1. I wish it was 7355 though you can find cheap used ones of that.
So so which one is it and is it easy to install?
Thanks for your help

Huawei 906e is cheaper (Cat 4), the EM7455 is about 30% more expensive (CAT 6) and may support more bands world-wide. No chance using EM7355 due to whitelist - otherwise it would be perfectly compatible.
Double-check FRU before buying as generic ones won't work unless the USB IDs are the same as whitelist. Allegedly you can convert them to Lenovo though I have been personally unsuccessful.
