The Multi-Network eSIM

Business continuity starts with connectivity that adapts

Managing devices across carriers shouldn’t require a carrier for every device. Kajeet smartSIM™ is a single eSIM that automatically switches among all three major US networks, providing your IoT fleet with uninterrupted connectivity without manual SIM swaps, truck rolls, or multiple vendor contracts. Backed by our Sentinel® platform, every device is remotely activated, monitored, and optimized — from a single dashboard, anywhere.

Who can benefit from Kajeet smartSIM™?

IoT solution developers
Businesses that have people in the field
Telehealth device manufacturers
Schools and libraries managing hotspot programs
ANY ORGANIZATION that requires a reliable Internet connection

Solution Overview

Meet Kajeet smartSIM

See how Kajeet smartSIM gives devices access to multiple major U.S. carrier networks and lets you switch carriers remotely, with no SIM swaps.

Summary

See how Kajeet smartSIM puts access to multiple major U.S. carrier networks on a single SIM, in any form factor. Powered by Sentinel, smartSIM lets customers choose a carrier and switch it remotely over the air, with no SIM swaps or truck rolls. Customers get one managed provider instead of multiple carrier bills, plus built-in content and web filtering. The SIM keeps IoT sensors, field service teams, telehealth devices, hotspots, and kiosks connected.

Kajeet smartSIM FAQs

How does Kajeet smartSIM differ from traditional SIM cards?

Unlike a traditional SIM tied to one carrier, Kajeet smartSIM can dynamically switch between carrier networks, improving uptime, flexibility, and reducing the need for physical SIM swaps or on-site maintenance.

Who is the Kajeet smartSIM designed for?

It’s ideal for organizations managing large or geographically dispersed IoT deployments where reliable connectivity is critical.

Can I manage multiple devices across different locations easily?

Yes. Through Kajeet’s Sentinel® platform, you can view and manage all your connected devices, data usage, and network profiles from a single dashboard, no matter where your devices are located.

How is network switching managed?

Switching is handled automatically over the air (OTA) - there’s no need to manually change SIMs or adjust configurations. Sentinel’s remote provisioning makes this seamless and secure.

What type of security does Kajeet provide?

Kajeet operates on a highly secure, carrier-grade network with built-in data protection and network redundancy, ensuring your IoT deployments stay safe and reliable.
