Cat-M1 and NB-IoT coverage

Cat-M1 and NB-IoT are next-generation IoT-specific networks that are currently being deployed internationally. Hologram will continue to develop this service as the network matures. For the most up-to-date information for your deployment plans please contact

At present, Hologram is fully deployed on the following networks:

Cat-M1 USA: Multiple Carriers

Cat-M1 International: Globally the Cat-M1 roaming scenario isn't fully standardized yet, so we are still in a holding pattern while our partner carriers deploy. We are working closely with carriers to get a timeline. Our plan is that by the end of the year/early next year we will have major international carriers enabled.

NB-IoT USA: T-Mobile's NB-IoT network is restricted to beta access SIMs only. Please contact for more information.

NB International: Same as Cat-M1 International.
