⚙️ Fit Notes

• This is a WWAN M.2 Key-B module (30x52). It is not an SSD and will not work in M.2 Key-M NVMe/SATA storage slots.
• Your laptop must have a WWAN-ready configuration (proper WWAN slot, antennas, and approved BIOS support). Many business systems require an approved/whitelisted WWAN card.
• Carrier performance depends on your region’s supported bands and your plan/SIM provisioning.
• Driver/firmware support is OS- and OEM-dependent (some systems install drivers automatically, others require OEM driver packages).
