Programmable Wireless: Cellular Connectivity for IoT

Twilio Super SIMs and Programmable Wireless APIs let you add cellular data and full messaging capabilities to your Internet of Things (IoT) devices. Our REST APIs allow you to manage massive fleets of IoT devices just the way you choose.

Whatever your use case — or however how far you’ve progressed on your IoT journey — this page will provide you with the resources you need.

Get started

Kick off your IoT endeavors by ordering a Twilio SIM. If you plan to use a Twilio Developer Kit, a SIM comes included — or you can head to the Console to order some standalone SIMs. Need a hand? Here’s some helpful guidance.

You can use the SIM with a compatible IoT device, or a mobile phone or tablet. Whichever you use, you’ll need to configure its Access Point Network (APN) setting first.

Here are some suggestions for trying out your SIM with a variety of IoT devices:

• Explore Programmable Wireless’ capabilities using popular prototyping products.
• Get application code for key IoT use cases with Twilio Blueprints.

Build your IoT product

Twilio Developer Kits enable you to bring your ideas to life by making it easy to prototype IoT products. Our Developer Kits come ready with hardware components, software tools, sample code and Twilio SIMs for connectivity.

Narrowband IoT kits

If you’ve received a Twilio T-Mobile Narrowband IoT (NB-IoT) Developer Kit, we have a setup guide just for you.
