Global Roaming

As of today, NB-IoT roaming is relatively limited, and few network providers have offered multi-network NB-IoT access for global IoT deployments. One reason is that operators are currently transitioning from a pure volume-based intercarrier billing model to one that also incorporates base pricing per device.

PSM and eDRX Availability

PSM and eDRX are two important features to deliver the best power-saving capability in cellular LPWAN. Therefore, it's recommended to ensure they are supported with NB-IoT network services when the low-power requirement prevails.

Technology Availability

NB-IoT standardization was completed in 2016, and yet technology roll-out has been slow. So far, less than one-third of all countries have had NB-IoT deployed.

NB-IoT hardware recommendations


As NB-IoT has not been deployed on a global scale yet, we recommend using cellular LPWAN modules that support not only NB-IoT but come with a fallback to common RAT types. Contact one of our experts to help you with your module selection.
