thinkpad P50 WWAN connection won't detect SIM Card

2019-02-04, 15:39 PM

Hello,

I own a Thinkpad P50 and I found it has a SIM slot under the battery, when i put my SIM card inside it will not detect any connection eccept for WiFi connections. 

I read online that it had to be enabled in the BIOS and i checked, it was already enabled.

Also I downloaded the WWAN Sierra Wireless Driver from the lenovo website and installed it, and nothing!

I then checked in device manager to see if the driver was there, and all I saw was the Sierra Driver under "Sensors" (no idea why it wouldn't be under the "Network" tab but ok...) 

I saw in a different form that this issue could be fixed by downloading a Sierra OCT tool but I got an error message saying that the modem couldn't be detected.

also I checked windows System Information and when i clicked on modem there were no informations for the modem.

I'm completely lost, I don't know what else to try....

can anybody help?

Welcome to the Community

Most likely, the wwan modem is absent in the laptop. What's the laptop MTM? It's needed to check out the specification. If the laptop model is CTO, provide me, please, its s/n via the forum private messages service.

By s/n you've provided the factory configuration doesn't include both wwan antennas kit and wwan modem. This is a specification by MTM matched to s/n:

The factory specification of the laptop MTM 20EN0007PB doesn't include the wwan modem, it could be installed separately.

Re:thinkpad P50 WWAN connection won't detect SIM Card

2020-09-01, 7:43 AM

Is it possible to check a P50 if it is WWAN upgradable or not without opening it and looking at the WWAN slot if the antenna cables are present?

 

The model numbers are not all listed at the PSREF web site https://psref.lenovo.com/Product/ThinkPad_P50

Therefore it is diificult to find this information checking PSREF.

 

For example I have looked at two P50:

 

  1. 20EQS3B31V does have the WWAN antennas and I could successfully install the WWAN module
  2. 20EQ0005GE doesn't have the WWAN antenna

 

Both models are not listed in the PSREF web site.

When I only check the model number I don't know if the WWAN antennas are there or not.

 

Or is it possible to find this information somehow without PSREF?

 

Thanks.

Not all models are listed on the PSREF site, only bestsellers for the retail market are there.

 

Take a look at these pages

  1. https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-p-series-laptops/thinkpad-p50/20eq/20eqs3b31v/parts/display/model

 

wwan upgradeable, has a wwan antennas kit

 

2 https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-p-series-laptops/thinkpad-p50/20en/20en0005ge/parts/display/model

 

non wwan upgradeable.

 

Also, this laptop specification for EMEA region w/out country code in the MTM is below
