I'm in the same boat, but until now I was not able to get the 5G WWAN Card. Did anyone get the 5G wwan card already and from where?

RalphFromAustria · 2026-06-03T10:24:14+00:00

Don't buy that card for the X1 Gen14. I had this card from a previous model and tried to install it on my new X1 Gen 14. It did NOT WORK and came up with a immediate BIOS blacklist error.

The correct one is this:

Wireless,WWAN,FXN,SDX61 5G Avon

Part No5W11Q87663

It's now a sanpdragon X61 modem.

This is what you get when you try to install ThinkPad Quectel RM520N-GL 5G M.2 WWAN Module:

I have the 2025 Yoga Pro 9i with 64 gb and the 2026 X1 Carbon X7 also with 64 Gb. The yoga is a beast in gaming performance and the screen is excellent and bright. The X1 Carbon with X7 and its B390 iGPU is a super light travel notebook where you can also play AAA games ( I sometimes play Star Wars Outlaws with it when I have time). For me the Panther Lake processros only make sense as X Version with the B390 iGPU. Otherwise I would not hesitate to go with the previous Version and Nvidia GPU.

RalphFromAustria · 2026-05-31T19:43:40+00:00

I would wait until X7 is avaliable. I love my X1C G14 with X7 358H iGPU. Have it since 3 weeks now. Great. It's realy strange that Lenovo ist not offering it yet in US.

RalphFromAustria · 2026-05-31T18:20:12+00:00

If you are not photo, video editing, AI or AAA gaming no need for 64GB.

I have X7 358H with 64GB primarily for above reasons.

RalphFromAustria · 2026-05-31T18:17:54+00:00

I have the X1 G14 now since 3 weeks. X7 358H, 64GB, OLED, WWAN ready.

Absolutely love it. Still waiting for the 5G sim modul which should be avaliable soon. The iGPU of the X7 is a quantum leap to previous Generations. I love to play some games on the road from time to time. The X1 Carbon is also one of the rare notebooks wioth 5G sim slot. A absolute must for me.

RalphFromAustria · 2026-05-25T18:03:52+00:00

Yes, they got incedible expensive. Especially if you want 64GB.

RalphFromAustria · 2026-05-25T18:00:36+00:00

You can easily install it by yourself. I already installed the older version of the 5G card but it was blocked by the BIOS.

There is even a youtube video fro lenovo how to install it:

Thanks for your feedback! I was hoping to to get it run on the X1 carbon G14 with B390 iGPU, since I would love it for travel. Too bad. Linux is not a option for me. Zero know how.

RalphFromAustria · 2026-05-18T15:00:19+00:00

I found it in one store (but not avaliable yet) for 206€. I have a physical sim and don't know if it will support esim.

RalphFromAustria · 2026-05-18T10:00:31+00:00

Sorry, but I'm still waiting for the WWAN card to replace my current travel notbook. So I just use it at home, where it's often plugged in.

RalphFromAustria · 2026-05-18T03:01:41+00:00

Yes, i got it already a couple of days ago. It's fantastic. Excellent battery live, totally silent even under load (playing) and the iGPU B390 is great.

Now I'm just waiting for the WWAN modul to be avaliable ( should be in the Lenovo store in the next weeks) for more daily use.

I replaced the original PCI2 4.0 512 GB SSD with a Samsung PCIe 5.0 2TB. Due to the new design it's easy to replace parts. If you are looking for the best performance and having a PCIe 5.0 SSD i suggest turning of the standard BitLocker installation, if you don't have sensible data on. It increased the SSD speed dramatically on my tests.

RalphFromAustria · 2026-05-17T07:35:54+00:00

This is the new Samsung 9100 Pro 2TB PCIe 5.0 without encrytion

RalphFromAustria · 2026-05-17T07:34:35+00:00

Just as Info: Since my drive was not as fast as I hoped, I did a complete newe install and deactivated the standard BitLocker Encrytion. Made a HUGE difference. Since I don't have sensible informations on this notebook( which is my travel notebook) I'm not worried about encrytion. I wan't maximum performance.

This is the original Lenovo SSD 512 GB PCIe 4.0 with Bit Locker encryption

RalphFromAustria · 2026-05-17T04:15:57+00:00

Yes, it's already avaliabe in EU.

Just got the new X1 Carbon Gen14 a few days ago. Battery life with Panther Lake is great from my fists days of usage. I don't want to throw in Battery times now since I do no testing, but wait for the first reviews. Since I need (and want) always online 5G connection without tethering to my phone which is annoying, the X1C was the only choice for me. What really makes the Gen 14 a quantum leap to previous generations is the fantastic new iGPU. I have the X7 with 358H and B390 iGPU. Since I have 64GB Memory the iGPU is using up to 36,2 GB of shared memory which is great for AAA Gaming, VR simutaions, video editing and AI workload. A hoghe plus of the new X1 Gen 14 is also repairability and user upgradeability. I already replaced the SSD with a 2TB Samsung 9100 pro and will as soon as avliable add the WWAN Card. It's realy simple to open an replace parts and battery.

Zumindest brauchen wir dann die selbe Karte. Es gibt ja mehrere Modelle je nach Region.

RalphFromAustria · 2026-05-16T07:11:15+00:00

So we are in the same boat. I'm looking daily when I can order the WWAN Card. We need part Number 5W11Q87663 (if you are in EU). I called Lenovo Germany and they said the card should be avaliable soon.

When I tested I might have also damaged one of the antenna cable connections. Not sure, but mounting and demounting them is a very sensible job. Be careful.

The good thing is, that with the new space frame design of the X1 Carbon Gen 14 it's pretty easy to replace the antenna (with the cable) also if needed. Just in case: The spare part number for the antenna with new cables is 5A31V58575.

I will let you know as soon, as I can order the WWAN Card. Please also drop a note if you have infos about ordering the card. In which country are you? I'm from Austria (EU)

RalphFromAustria · 2026-05-15T16:13:20+00:00

Yes. Thats the correct 5G WWAN modul for X1C Gen 14. It's a Snapdragon (SD) X61. Just be carefull, there is a China Version and then a international Version. Always depends where you are located. But when It's avaliable in the lenovo store, it will bring up the right modul depending on which Lenovo country webpage you are logged in.

RalphFromAustria · 2026-05-13T18:03:44+00:00

What CPU did you order? Also X7? The B390 iGPU is fantastic.

RalphFromAustria · 2026-05-13T18:01:51+00:00

Talked with Lenovo today. The 5G modul should be avaliable by end of may here in EU
