For most people, it’s not the end of the world outside of hurting the resale value. For example: I don’t want a WWAN card on most Lenovo laptops after it’s ~18 months old or it just has to come with the deal - that’s because many of them tend to use older network technologies that are close to death, especially pre XX40 models. The cards are whitelisted, so I can’t decide that the cards sanctioned by Lenovo are too old to bother with, but I can buy any card I like as I can with a Dell Latitude. It’s generally not something that’s cared for after it gets to be too old.
In this laptop, the current card the US models use is the Sierra Wireless EM7355 (FRU: 04W3801). It’s an LTE card (which is good) and outside of regional issues one card is used with these machines so it’s nowhere near as bad, but even then it’s not something people always care about - especially if you take my attitude and don’t care if it comes with one, but if it doesn’t NBD. In the past, it was done with a few specific cards and after 18-24 months, they’re all either dated and not worth having (unless you NEED IT) or in the case of a 36+ month machine, all obsolete (usually 3G GSM or CDMA). On top of that, the cards are highly regionalized - not an issue for most but can be a pain for travelers. I have yet to buy ex business hardware where someone sunk money into WWAN hardware - much less find it in the hardware roster. It’s that rare of an option.
I have the same rule with Dells but to a lesser degree since they don’t have a WWAN WL and if I can use it, I can fit something like an E6X40 card in the same PCIe slot if it’s known to be technologically compatible; I draw the line when the laptop is so old it’s MiniSIM based like the E6X20/30 series.
Unless you NEED a WWAN card, I wouldn’t risk it over a part few people seldom care about after 24-36 months. Get a MiFi hotspot if you really need it like the rest of us with old laptops who want a backup. You’re at 96 months/8 years with this, so you’re at the point buyers like me will just ask for a price break and use a MiFi hotspot the one or two times per year they probably need it. You may not even be ABLE to buy it anymore and unlike old machines, you can’t flash the BIOS - Intel Boot Guard ruined that. Are you doing this to protect yourself from losing $50-60 worth of lost resale value (which will be completely lost if you ruin it since it’ll be a parts machine) or do you need it?
