Latitude 7300 and WWAN card, which model is officially supported?

[waregen]

Got latitude 7300, it has sim card slot, and a slot ready for WWAN card with two antenna cables near it.

Which WWAN cards does one need to buy to get LTE internet? Which one is officially supported?

Welcome to the Dell Community @waregen 

The Dell wireless 5821e is the only one I see in the online Latitude 7300 Setup and Specifications PDF, page 15.

Mobile Broadband Qualcomm Snapdragon X20 Global Gigabit LTE (Optional)

And the only driver listed on your driver support page.

Best regards,

Well that is the one I got and is already inside, drivers installed correctly and the sim card is recognized.

Asking to remove pin, it just would not connect.

When putting it in, there are two antenas inside, I connected white to MAIN and black to AUX6, the lowest number AUX. 

But win10 would not connect, it just does not react or some parts are greyed out.

I played for two hours with custom APN, but no luck.

#6, Aux 1 is not used

#8, Aux 3 is Black (gray with black tracer)

#7, Aux 2 is not used

#5(red), Main is White (gray with white tracer)

If it still doesn’t work after you put Black on Aux 3, what are the two digits that end the Foxconn PN?  T77W968.??   What parts are grayed out? APN should be Automatic.

Thnx for the info https://i.imgur.com/5uv2zEX.jpg Will have it again in hands monday, will update how it goes when moving the cables. and the foxconn PN

[waregen]

Well, antenas switch did not help.

Will try clean install on a temporary ssd and see how it goes.

Clean reinstall did not help.
Default drivers that windows 10 pulls did not work
Dell latest drivers with firmware did not work
Latest bios plus everything as up-to-date as possible

The two last digits that end the Foxconn PN are .04

Not really sure what is more to try.
Can anyone really 100% confirm that 7300/7400 works with dw5821e?

Here is the pic of the card inside the notebook,
with all the labels visible and connected antennas

I’m sure it works, if the laptop is purchased from Dell with the DW5821e as a preinstalled option. However, I’m not so sure when the DW5821e is purchased as an aftermarket part, especially when it appears in the US FCC database, like your .04 HMGJ3. What the FCC usually gets are engineering samples not meant for consumer use. If I were you I’d use your provider’s BYOD check database to determine if the device will work on their network.

So, it is solved.

Contacted the support that does on site repairs and they had me send them picture of the WWAN so that they have the serial on it and then send me link to a tool that I run.

site has it labeled as
Dell Wireless 5821e and Dell Wireless 5829e/Qualcomm Snapdragon X20 LTE Customer Kit Tool

I run 1_Click_Cust_Kit_Tool.exe and it was just a single button to enable wwan kard or whatever it was labeled.

And then it just worked.
