Ericsson Cradlepoint MC400 modular modems allow Ericsson Cradlepoint MC400-capable branch, mobile, and IoT routers to be easily field upgraded with the most recent industry-leading cellular capabilities. The Ericsson Cradlepoint MC400 modular modems combine enterprise reliability with industry leading performance. Available modems include both LTE Advanced and 5G for fast robust connections.

## Notable Features

- Better return on investment with the capability to upgrade to the latest modems without replacing the original hardware.
- Higher availability by installing a second modem for failover connectivity.
- Lower data plan costs by automatically switching to the second modem/SIM when the data plan cap on the primary modem/SIM has been reached.
- Certified versions are available for public safety networks worldwide.
