INFO. Installing a M.2 SSD in the WWAN slot E5250?? IT WORKED
I bought a 2016 Lattitude E5250 a few months ago. Noticing the WWAN was a mini PCIe slot. Did a search to see if any SSD's would work as a 2nd back up drive. Found a YT vid "Dell Latitude 5401 - install second SSD into WWAN slot" He made the point to use the M.2 NVMe PCIe type card. So looked on the bay and found a cheap £10 TOSHIBA 128GB M.2 2230 PCIe NVMe SSD Just to try out. My WWAN should have the 2242 SSD card. Although too small to screw down. I was able to make the card stable, using some masking tape and sticky pads. The SSD was recognised from start up, no messing with bios. After usual setting up for any new HD, It worked perfect Still working perfectly after 2months. Speeds of the New drive has settled down to: Read = 850MBs Write =600MBs

Thanks for sharing @Derek M! I was able to do the same in my E5470.
Now if I could just figure out how to get the system to recognize the regular SSD(connected with a Dell SATA transposer cable)....

Very interesting thread.
I wonder, could the reverse be also true? Could a WWAN card be used in an nVME M2 slot.
Has anyone ever tried it?

You would need antennas for the WWAN anyway. So if You already have WWAN antennas inside the laptop then there also is a slot for the WWAN card, right?
I don't think installing a WWAN card into a storage m.2 slot would work, even if You retrofit some random antennas.

This is an old computer already, but I will chime in and give my two cents.
Yes, it is possible to install an m.2 SSD into the WWAN slot and use it for storage, as OP stated. However, Peto Pedro is correct in the fact that it's not possible to boot from that drive. You still need to use the SATA drive to boot.
Why I needed the m.2 to boot was an interesting turn on events - the battery died on a E5250 and I had lying around a 4-cell battery for E5450. Unfortunately that battery is bigger and occupies the space for 2.5'' drive. Looks like I still need to order the correct battery, as m.2 slot is not booting...

I have the same problem, battery break, new battery order is 6 cell so :
if the computer does not boot on an m2 SSD, has anyone tried with mSATA? looks like there is a slot under the SATA 2.5 SSD ?

Hi, I'm the original poster Along with the M.2 NVMe in the W/WAN slot. I have a Kingstone 480gb M'2 Sata with the appropriate cage adapter. Works perfect.

Hi again looking on eBay myself i see there Msata adapters. They slot in in Just like the SATA 2.5 drives. These can take the longer and cheaper MSATA SSD. I'm getting one myself.
