The nationwide network built for IoT.

Our Narrowband IoT (NB-IoT) network is the first nationwide network designed specifically to provide reliable, secure cellular connectivity for IoT devices. Our NB-IoT network offers nationwide coverage, features to extend battery life, and authenticated LTE communication.

Coverage not available in some areas.

Low-cost scalability.

Narrowband gives you a dedicated highway using existing infrastructure. Because it can operate in guard bands – the network equivalent of driving down the shoulders on the highway—NB-IoT carries data with greater efficiency and performance than LTE, helping to control costs over time.

Improved performance and longevity.

Products designed with NB-IoT can provide up to 10+ years of battery life while transmitting small periodic amounts of data. It’s an ideal solution for IoT in smart cities, building automation, asset tracking applications, and more.

Additional security and control.

Secure your NB-IoT operations with T-Mobile’s Network Services Enablement
Platform (NSEP). It provides centralized visibility and flexible device
and data management capabilities specifically for Narrowband.
