About

Bring smart devices online, from anywhere

Internet of Things (IoT) deployments hinge on secure, stable internet connectivity. Businesses are shifting away from old-age WiFi and ethernet connections in favor of cellular data. With stronger security and broad, global coverage, Telnyx M2M and IoT SIMs enable vendors to activate, configure, and monitor devices remotely, no matter where they’re deployed.

All Telnyx SIMs are eUICC enabled and are available as triple-size plastic SIM cards, eSIM chips (embedded MFF2) and over-the-air eSIMs.

Customer Stories
We used several different carriers before Telnyx, but it was a huge headache to manage. From data limits, to billing, to having to switch SIMs as devices moved around to different parts of the world.
