Quad LTE-A Cat-12 cellular module for Balance SDX, SDX Pro, and EPX FlexModule Plus bays
The Peplink FlexModule Plus 4x LTEA Cat-12 is the quad-cellular expansion module for SDX-class FlexModule Plus bays. Four embedded LTE-A Cat-12 modems on a single FlexModule Plus card, hot-swappable into any Balance SDX, SDX Pro, or EPX-M8 chassis. The right choice when maximum cellular redundancy at moderate cost matters more than headline per-modem throughput. SKU EXM-4LTEA-Q.
Why pick the 4-modem variant
Two FlexModule Plus 2x 5G modules deliver 4 cellular paths in 2 bays at premium price. One FlexModule Plus 4x LTEA Cat-12 delivers 4 cellular paths in 1 bay at moderate price, freeing the second bay for fibre, Ethernet, or SIM Injector. Pick the 4x LTEA Cat-12 when:
- You need 4 active cellular paths but the per-modem throughput needs are modest (200-400 Mbps real-world Cat-12)
- Bay count is the constraint and you want to keep bays free for non-cellular FlexModules
- Cellular spend at scale matters, Cat-12 modems are meaningfully cheaper per path than Cat-20 or 5G
