Lenovo ThinkPad Quectel RM520N-GL 5G M.2 WWAN Module — Mobile Broadband for Your ThinkPad

5G Sub-6Quectel RM520N-GLBuilt-in eSIMLenovo option

The Lenovo ThinkPad Quectel RM520N-GL 5G M.2 WWAN Module (part number 4XC1Q34838) is an internal M.2 mobile broadband card that lets a supported ThinkPad connect to the internet over the 5G, 4G LTE and 3G networks with a SIM or eSIM, without a hotspot or USB dongle. The Quectel RM520N-GL module supports 5G NR Sub-6 in standalone and non-standalone mode, with receive diversity and four antenna connections, in the M.2 3052 size with a PCIe interface. In practice it keeps a field engineer, sales person or manager online on the road, with the connection built into the laptop.

Compatibility — check before buying:
It only works in the ThinkPad models Lenovo lists, and only if the laptop is WWAN-ready — that is, built at the factory with the WWAN antennas for 5G installed. A ThinkPad without WWAN antennas cannot use it, and antennas are not in the box. Lenovo lists: ThinkPad T14s Gen 5, T14s Gen 6 (Intel and AMD) and P16v Gen 2 (Intel). The same RM520N-GL module is sold under other Lenovo part numbers for other ThinkPads, so this kit is not a universal 5G card. A SIM or eSIM data plan from your mobile operator is needed. Send us the laptop’s machine type (the first four characters of the MT on the label, e.g. 21MC) and we confirm it before you order.

Frequently Asked Questions

Will it work in my ThinkPad?
Only if your model is on Lenovo’s list for 4XC1Q34838 and was built WWAN-ready with the antennas installed. Send us the machine type from the label and we check it.
Are antennas included?
No. The card uses the WWAN antennas already built into WWAN-ready ThinkPads. A laptop built without them cannot use this card.
Do I need a SIM card?
Yes, a data SIM or an eSIM profile from your mobile operator. The module has a built-in eSIM; physical SIM use depends on the laptop.
Is this the right RM520N-GL kit for my laptop?
Lenovo sells the same Quectel RM520N-GL module under several part numbers, each for different ThinkPads. 4XC1Q34838 is listed for T14s Gen 5/Gen 6 and P16v Gen 2 (Intel); 4XC1Q24435 is listed for X1 2-in-1 Gen 9/Gen 10 Aura, T16 Gen 3/Gen 4 and P16s Gen 4 (AMD). Always order by the list for your model.
Singular Expert Insight
We suggest checking the machine type before ordering any WWAN card: the model name alone is not enough, because WWAN-ready and non-WWAN versions of the same ThinkPad exist. For 5G, the laptop must have the 5G antenna set. If your laptop is not WWAN-ready, one of our 4G and 5G routers shares mobile data over Wi-Fi instead. See also our ThinkPad docks.
