I recently bought a X1 Yoga 2Gen in a HK reseller which does not come with any Sierra EM7455 WWAN card. Would like to know if I can add the card in order to use mobile network for connecting the internet. The machine type is 20JDCTO1WW. Any reply would be appreciated. Many thanks.

Welcome to Lenovo Community! And happy to have you here.
As your system is CTO model can you message me your System's Serial Number through private message 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!

Thanks for sharing the details, sadly your system is not WWAN ready as required Antennas are missing from your system and also it can't be upgraded later on according to this thread.

It is possible to retrofit the antennae. Requires taking apart the entire notebook. There are several threads in this forum about it. I did it on my x1 yoga 2nd OLED and WWAN now works wonderfully.
