Twilio Programmable Wireless lets you add cellular data, voice, and SMS capabilities to your connected devices. Our REST APIs ease managing large device fleets, allowing you to control your IoT devices in the way you choose or to build an entirely custom deployment.
Order and register your first SIM, configure the APN to point at Twilio, then dig deeper into sending machine-to-machine commands, making and receiving voice calls or sending and receiving SMS. Whatever your use case, Programmable Wireless will help you stay connected.

Using Programmable Wireless usually begins with a SIM order - head to the console to pick up your SIMs now. Whether you're using an IoT device or testing Wireless through a handset, you'll need to set the Access Point Network or APN.
After that, your path will depend on how you're using Wireless:
Programmable Voice and Programmable SMS are offered as a developer preview for Wireless SIMs.
Programmable Wireless SIMs are capable of making and receiving voice calls and sending and receiving SMS messages using TwiML® in the style of Programmable Voice and Programmable SMS. This functionality is offered as a developer preview; it is not recommended that you use this functionality to power a production system today.
