Automatic network failover
Telnyx SIMs automatically connect to the best available network, providing a seamless connectivity experience with built-in redundancy for maximum uptime.
Pay-as-you-go pricing
Pay $1 one-time-charge per SIM and only pay for the data you use, with plans as low as $0.0125 / MB, and low fees for inactive SIMs.
Data limits, alerts, & reporting
Set custom thresholds for alerts & limits across one SIM card or a group of SIM cards. Export bespoke reports with in-depth usage data, network registrations, device locations and more.
Private LTE networks
Connect devices directly to your corporate network with Private Wireless Gateways to avoid the dangers and inefficiencies of the public internet.
Public static IP
Map public IP addresses to your SIMs so you can connect to your devices from other places on the internet, expanding their usability and making it easier to scale your IoT solution.
Say goodbye to minimum order quantities and monthly data usage lock-ins. Pay as you go, for what you need and nothing more. Contact our team for custom pricing!

Understanding eUICC and eSIM
Learn about the similarities and differences between eUICC and eSIM, and how they can benefit your IoT and mobile devices.
Futureproof your IoT deployments
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.
