Cat-M (LTE-M) and NB-IoT are low-power cellular technologies designed specifically for IoT devices with reduced bandwidth needs and extended battery life.
Hologram is actively expanding via new roaming agreements. Check our Hologram coverage page for the most up-to-date availability of Cat-M1 and NB-IoT in your area.
Note: Carriers typically prioritize standard mobile data (e.g., 4G/5G) over low-power IoT technologies (like Cat-M or NB-IoT). In congested areas, they manage network resources by giving higher scheduling priority to regular smartphone traffic, which can temporarily limit bandwidth or response times for IoT connections. This approach ensures mainstream user experiences remain smooth while still accommodating IoT data within each cell’s capacity.
