Twilio IoT provides global cellular connectivity for your Internet of Things devices. Our developer documentation will show you how to integrate our connectivity products into your IoT devices, applications, and backend infrastructure.
Twilio IoT connectivity is delivered through Twilio SIMs that are fully manageable through our software APIs. With Twilio SIMs, you can go from prototype to production with CAT-M1, LTE, Narrowband, and 2G/3G:
- Super SIM — Multi-network connectivity for IoT deployments across the world.
- Programmable Wireless SIM — Connectivity for Broadband IoT applications through T-Mobile’s global partner networks.
- Narrowband SIM — Connectivity for Massive IoT applications on T-Mobile’s NB-IoT network in the United States.
These SIMs, which are available in multiple card and module form-factors, are backed by powerful APIs from which you can construct sophisticated fleet management systems for your application.
Both Programmable Wireless and Super SIM provide access to hundreds of cellular networks around the world, through one SIM, with one simple bill and pricing model. Differences exist in pricing — mostly affecting African countries — and certain functionality.
|Super SIM||Programmable Wireless|
|Coverage||Multiple global tier-1 networks||T-Mobile USA and its roaming partners|
|Connections||2G, 3G, 4G, Cat-M (global)||2G, 3G, 4G (global); NB-IoT (US only)|
|Network steering||You control which networks your devices use, wherever they are deployed||Subject to T-Mobile USA’s steering|
|Flexibility||Twilio’s Distributed IoT Mobile Core provides unified functionality via one API across all supported carriers||Dependent on networks’ own cores|
|Performance||Twilio’s Distributed IoT Mobile Core provides consistent global latency rates||Dependent on networks’ own cores|
We generally recommend new customers choose Super SIM. However, our IoT specialists will recommend the best solution after a conversation about your specific technical requirements.
Whichever SIM you select, you’ll need to know how to instruct your IoT devices to connect to the network. You’ll also need to understand the basics of SIM management.
Start developing an IoT product based on Twilio IoT using our Getting Started Guides to get your proof of concept or prototype up and running.
Mobile cores are a key part of any cellular network: they manage SIM access, and route traffic across home and roaming (‘visited’) networks. Unlike carriers’ cores and those of many of our competitors, Twilio’s Distributed IoT Mobile Core was built solely for IoT.
The Twilio Distributed IoT Mobile Core is deployed to multiple data centers around the world. It provides our customers with total flexibility and scalability for their global deployments. Devices get a consistent connectivity experience, whether they’re deployed in Los Angeles, Berlin, Taipei, or Nairobi. The result: less device downtime, and a real choice of which networks to use in any given region.
Need assistance with integrating your chosen cellular module with Super SIM and other Twilio SIMs? Then consult the new Cellular Module Knowledgebase for general and module-specific advice and insight.
Partner products have a Twilio SIM built in. You don’t need to register a SIM with Twilio to get started — it’s already built in!
Twilio IoT provides great cellular connectivity, but its real strength lies in its programmability — the key to creating sophisticated connectivity management and monitoring tools able to scale to millions of devices and beyond that are tailored specifically for your needs.
- Use the Super SIM API to manage Super SIMs, individually or in fleets.
- Use the Programmable Wireless API to work with Programmable Wireless SIMs and Narrowband SIMs.
The API documentation contains all you need to connect your own systems to your Twilio IoT SIMs, including sample code.
We can all get into difficulty when we’re beginning a new project. Sometimes we’d just like a little further clarification about a feature or a setting before continuing.
