LENOVO THINKPAD 450s WON'T DETECT A SIM CARD

2017-09-26, 9:30 AM

Hello Guys. 

I'm running on ThinkPad T450s. I've tried to install a SIM card in its tray with no detection at all. After going through google, Wireless WAN, Ericsson® N5321 and Wireless WAN, Sierra Wireless EM7345  came into my attention. 

  1. I went to my Device Manager where I found non of the adapters installed. Is it possible for them to be installed without being displayed on Device Manager? 
  2. I've seen some suggestion to replace the current Wi-Fi adapter with Sierra Wireless EM7345. My concern is if I'll be in position to access Wi-Fi after its adapter being replaced with this Wireless WWAN adapter. Are these Wireless WWAN adapters provide access to Wi-Fi? 
  3. Most of the Wireless WWAN adapters I've gone through eBay works with X230s X240 W540 T440P T440S W540; will these works well with this T450s of mine?

 

Thanks in advance. 

Regards, 

Cathbert.

There isn't a wwan card in the factory configuration, while the wwan antennas kit is there.

So, you might purchase and install the wwan card yourself:
Ericsson N5321 HSPA+ 21Mbps M.2 - FRU 04W3842
Sierra EM7345 LTE/HSPA+ 42Mbps M.2 - FRU 04X6014

Do it well, worse becomes itself

Hi

Most likely the wwan card isn't installed in the laptop. Provide, please, its MTM code (it starts with 20BW or 20BX) to check out the factory configuration. If there are CTO symbols, send me laptop serial number via the forum private messages service.

Only Lenovo approved wwan cards for T450s will work in the laptop, with appropriate service p/n (FRU).

The wwan card will not work in the wlan slot, it even can't be fitted there. Of course, modern built-in wwan cards don't support wifi capabilities.

There is a common misconception that software named lenovo access communications (or something like that) is needed to operate the wwan card, and does not work on windows 8 or 10.  However you do not need this software, windows will work the cellular data by itself if you look though the internet settings.  ALso, if you're having sim card issues with it saying its not detected, check its inserted properly (might be the wrong way around).
