Dell Wireless DW5804/E371 4G (LTE-3G) PCI-E WWAN Card for DELL DP/N 01YH12 not for IBM/Lenovo/Thinkpad and HP

Bad investment for me.

I purchased a refurbished Dell e6230 laptop a few months ago, and an available option was an LTE cellular card. This DW5804 card fit the available M2 slot, was still current, and works fine with my carrier. It added a minimal additional charge to my existing AT&T shared data account for the convenience of an additional cellular device. Windows 10 had no problem recognizing the card. (Refurb'd laptop? - Sure. How else could I get a third gen i5, 3½ lb, 12 inch display, ultra-portable class laptop w/250GB SSD, 16GB of RAM, backlit KB, and cellular, not to mention USB3 & eSATA port, for under $225 lol. No brainer.) The Chinese seller shipped the new-in-package part with minimal fuss & delivery time, and absolutely no drama at all. Very satisfied.

Works great, I use it with Project Fi Data cards and they work perfectly.

Super! Thank You Amazon!

Firstly thanks to previous reviewer brdavis9 whose review made me decide to get this card. I knew it "should" work on my e6230/e6330 but hearing someone else confirm that is everything.So, I bought one of these for under $15 and liked it so much I bought a second.The story is that I have been waiting for over 10 years for an easy and affordable way to get a laptop online anywhere using the cellphone network and feel this card finally delivers on that. No more expensive lattes at Starbucks just to use their wireless. No more tethering my laptop to my iPhone and the rebooting laptop and/or phone until they decide to recognize each other.The download speed of 100mbps is supposedly the same as my iPhone 5s and it does feels like it, very acceptable. Card installs easily into the internal WWAN port and you can find drivers online pretty easily. Took the nano sim out of the family iPad which doesnt need it as it is only used at home on wireless, bought a quality sim card adapter so nano sim becomes regular sim card size, insert sim into sim card slot within battery compartment in back of laptop, AT&T network appears at top of wireless menu, click on connect and you're connected to AT&T 4G LTE. No passwords, no mess, very easy.Downsides, I have a bunch of Dell Latitudes of different vintages and this card only works on e6230 and e6330 which date from around 2013. It wont work on my older beloved e6410's or e4310 which is a shame.Also you'll need a good data plan as you'll chew thru data pretty quickly using a laptop on cellular service, especially if you watch videos. We have a family plan with plenty of data, but I still like to send a text message on my phone to *3282# afterwards to check how much data I used.Now I can roam freely with my laptop and go online/write/upload my scribblings to DropBox from anywhere with cellphone service. Next up will be a 7000 series Latitude with a Snapdragon x7 cellular modem with 300mbps download, but that's going to be a while ....
