2 days ago I upgraded to Win 10 Pro, yesterday I went to use my mobile broadband connection (4G) and noticed I wasn't able to "see" the cellular connection or activate it anywhere.
Checking in the device manager I see the hardware (Sierra Wireless, etc), although strangely the driver is from Microsoft (Generic Broadband Device).
Nothing I do seems to be able to make it work, I've uninstalled the drivers, rebooted, downloaded the current Lenovo driver package (which supposedly has Windows 10 drivers), it installs fine but still no mobile broadband is available to me.
I use this feature a lot, and would really like a solution to this...
Attached is a screen shot of the current driver situation:

Hi, I have the same issue on 2nd gen X1 (3460-2SG) that after Win 10 upgrade (from Win & Pro 64) lost Mobile Network but has WiFi OK?
Looked for updated drivers but found none...
Looked in "Mobile accsses" tool in previous profiles i had, and it states "device is not found" in front of the H5321 gw Mobile broadband driver.
I believe I'm talking about WWAn with Sim card.
Where do I find the card type and driver ver.?

Has there been any updates to this issue?
It seems like this is quite simply could just be a driver issue... Even though the lenovo driver package says it has Windows 10 drivers, it doesn't seems like it has the correct drivers. It's clear that if I force install the drivers for the Gobi windows doesnt' like them and reverts back to "Generic Broadband" drivers.

The below may apply to your situation:
If the card's firmware hasn't been updated before upgrading to Windows 10 the card will produce a yellow bang in device manager and not function. The current firmware doesn't allow itself to be installed running Windows 10 resulting in the system having to be rolled back to the previous OS, the firmware installed and then upgraded again to Windows 10.

That's a much, much older card then I have... so that will not work for me.
The problem here seems to be purely driver related... Even though Lenovo lists driver packs for Win 7, 8, 8.1 and 10...
What I just noticed was that the driver version is actually the same. Almost as if they just repackaged the same old driver.

Can you please post a screenshot of Device Manager showing the "Driver" tab of the Sierra Wireless device?
One of my colleagues updated his T440s with Sierra WWAN and ended up with driver version 14.9.10221.0. He did not manually install it, that's just what he ended up with after the Win10 upgrade. And WWAN is working OK on Win10.
So we think this must be some driver problem, now we are checking to see where that 14.9.10221.0 driver came from, and why you apparently didn't end up with the same version after your Win10 upgrade. And why this version doesn't seem to correspond to the version on the website. Anyway, we are still investigating this.

It certainly seems to be a driver thing... here is the screenshot, as you will see the driver is from Microsoft, and although in the device manager it says it's a Sierra Wireless EM7355, the driver is not and is a Generic MS driver:
