Digi Core Plug-in LTE modem
Modular LTE Connectivity with Carrier Smart Select and Dual SIM Support Across Major Carriers for Optimal Mobile Network Access
The Digi CORE Plug-In LTE Modem is a modular, swappable LTE connectivity solution that integrates with Digi enterprise routers and infrastructure devices for scalable, future-proof cellular access.
The Digi CORE Plug-In LTE Modem enables easy upgrades to LTE, LTE-Advanced, or specialized bands without replacing the entire router. It features dual SIM slots (software/hardware switchable), Carrier Smart Select™ for automatic optimal carrier switching, optional Digi eSIM accessory for remote provisioning, tamper-proof locking, external SMA antenna connectors, and support for Digi WAN Bonding (aggregation + failover). Certified with major carriers (including FirstNet Trusted™ in select models), it provides persistent connectivity via Digi SureLink® and remote management through Digi Remote Manager®. Ideal for future-proofing deployments in retail, industrial, transportation, and critical communications.
