DW5821E 3G/4G/5G Card, Network Adapter Card, for PCI Express M.2 Specification 3042 Type Key.B Slot, for PC, Laptops

I purchased this to install it on various Dell Latitude laptops and it works flawlessly. It works using T-Mobile and At&t, it did not work with Verizon but I think the issue was on their apn settings. This card even works using FirstNet cellular which is a must for any rapid responder! Unfortunately, it does not work on 5G LTE as advertised, only 4G, but the speeds are excellent, by far bearing my MR1100 hotspot. I also tried this on my HP laptop out of curiosity, but I was only able to get it connected to T-Mobile, using 4G LTE with okay speeds. Definitely, not good for other laptops not listed in the ad.

Waste of money. It is not 5g, and only compatible with Verizon and AT&T, who will not let you activate this modem because it's 4g.

When trying to use this with a USB SIM adapter, my computer kept complaining about drivers for it, and it sent me looking for proper drivers just to make this thing work. I found out that after getting the proper drivers, as long as I keep the USB adapter plugged and don’t reboot, it’ll eventually settle down and function properly. If you do try doing either of those, you'll once again have that driver issue loop all over again. Although it does EVENTUALLY work, I’m disappointed that it, despite the name of the product page, does NOT support 5G, it only have 4G LTE.

Took a bit to figure out how to setup the cellular conection on the pc but after a bit had it figured out. I have metro pcs sim linked to it and im getting speeds close to the 120$ plan from xfinity for only 30$ so the price for this chip and the card reader was well worth it and saves money in the long run. Depending on your location the speeds can vary greatly
