Purchased the T470s with 4G LTE modem. The Sierra wireless EM7455 is clearly visible in device manager with no errors and can be turned on and off, but it won't detect any SIM-cards (have tried updating, restarting, different SIM-cards), but nothing. Only asks to enter the SIM-card, but does not detect it when inserted.
How silly! Not touching the SIM-Card nor the SIM-tray, just rebooting the laptops (plural) 2-3 times, et voila! Now they connect via CELLUAR.
I guess we can blame Bill Gates for this and not Lenovo?

Ditto here. The very same Issue. All fine, drivers etc, but SIM-card is not detected.
This happens on TWO Lenovo T470s with two different SIM-cards so far.
Any solution? Any "utility" of some sort that still needs to be installed?
