Programmable Wireless

Programmable Wireless, developed in partnership with T-Mobile USA, provides cellular connectivity access for IoT devices by leveraging T-Mobile’s partner networks around the world. Our Programmable Wireless API allows you to manage massive fleets of IoT devices just the way you choose.

You can choose from two different SIMs depending on your use case and hardware. Both SIMs are available in multi-size SIM card (2FF/3FF/4FF) and embedded (MFF2) form-factors. Both SIMs types can be managed using the Programmable Wireless API or the Console.

Programmable Wireless SIM

Use Programmable Wireless SIMs to add 2G, 3G, or LTE cellular connectivity to your IoT devices. Send information to and from your devices over cellular data or machine-to-machine (M2M) SMS.

In the United States, Programmable Wireless SIMs will connect to the T-Mobile USA network. Outside of the US, Programmable Wireless SIMs provide access to T-Mobile’s partner networks around the world.

With pay-as-you-go data metering, Programmable Wireless SIM usage is billed per megabyte. This gives you the flexibility to use as little or as much data as you need with no commitments. Learn more about Programmable Wireless SIM pricing here.

Outside of the United States, Programmable Wireless SIMs are subject to network steering.

If you are interested in having access to multiple networks in the United States, or having the freedom to choose from the best networks around the world with no network steering, we encourage you to check out Super SIM.

Narrowband SIM

Use Narrowband SIMs to access the T-Mobile NB-IoT network in the United States.

Narrowband technology is designed to support massive Internet of Things (IoT) use cases, which are typically low bandwidth. Narrowband is designed to improve power consumption for devices that send small or infrequent packets of data. Narrowband’s technical fundamentals reduce the cost of connectivity and lower the cost of hardware.

Narrowband enables Massive IoT: connectivity that supports huge volumes of low-complexity devices that send or receive messages infrequently. Typical use cases include low-cost sensors, preventative maintenance monitors, utilities meters, and location trackers. Devices like these are often deployed in challenging radio conditions, such as in building basements or outdoors at the extremes of network tower coverage. They often rely solely on battery power and may need to stay operational for years between maintenance checks.

The Narrowband SIM supports data only.

For more information about the Narrowband SIM and Massive IoT, please see this page.

Twilio Narrowband SIMs can only connect to the T-Mobile NB-IoT network in the United States. They are not able to be used outside of the US.
