Carrier-Certified Cell Modems

Dramatically reduce time to market, certification costs, and risk with industrial modems suitable for low-cost M2M data plans and the Internet of Things.


Zoom’s line of carrier-certified industrial cell modems provide reliable wireless connectivity between your equipment and any Internet-connected equipment you choose. These USB modems are easily integrated into your system, and benefit from robust power supply and antenna design.
