Covering the WWAN antennas used by the Verizon 3G card?

I got one of these to toy around with as it was the best of the breed for netbooks due to the 11.6” screen (I also have a compatible screen so…) since it was cheap, However, the screen is cracked but I can fix that - the spare screen will work.

However, mine is the -1037NR, which means it has the HP WWAN card. Cool, right? Well, EXCEPT Verizon blocks new cellular activations on 3G/no VoLTE hardware so the card does me no good. I would like to “delete” it from the computer so I don’t need to worry about it’s existence when I go rebuild the OS. So yeah, this card isn’t going to do me any good and I’d prefer to remove it.

What is the best way to cover the WWAN antennas on the machine, so it doesn’t short anything?

This is how the cards are laid out in the 311:

Some manufacturers ship laptops with antennas preinstalled, but no WWAN card unless you pay for it. Those units have heat shrink tubes to secure the antennas.

Scotch tape works as well.

Usually it’s just a PCIe card, open it up and remove it.

Better yet, you can find another newer card and put it in as long as the amount of antennas is correct.

BIOS whitelist era HP, so may not work. And to make it worse, it has no SIM slot like the commercial notebooks where if you got a unit with a useless CDMA card you can run GSM hardware. I'd need to find a GSM eSIM card that isn't NGFF, or adapt it most likely. Or get a LTE Verizon card.

Might be easier to put Kapton tape over the antennas, remove and just not bother trying to make it work (and tape it down after isolation so they stay put). My phone can act as a hotspot - but I am open to it if I can get a cheap LTE card to check for a BIOS WL.

@nick Maybe there are cellular card with an onboard SIM slot instead of eSIM.

@tomchai Yeah someone tried the screen before me. It's obvious, but there was no damage - it took the replacement screen no problem.

Looks like they tried, couldn't do it, looked at a guide and gave up to me.
