To achieve globalcoverage and wide adoption of LPWA services, mobile The GSMA plans to maintain and update this guide on aregular basis, particularly with respect to the adoption of This document contains non-binding guidelines intendedto help mobile operators and solution developersto ensure interoperability and smooth roaming. Therecommendations have been developed by membersof the GSMA 5G IoT Forum based on significant globaldeployment experience gained since 2017 and practicalinsight regarding which features have gained market 1. Introduction 1.1Overview 1.1Scope NB-IoT and LTE-M are cellular radio access technologiesspecified by 3GPP to address the rapidly growing marketfor IoT devices requiring low power wide area connectivity.The two technologies have complementary performance This document considers and categorises the featuresassociated with NB-IoT and LTE-M up to and includingRelease 17, with a view to helping both mobile networkoperators and solution developers to differentiate 2. Enabling Global NB-IoT and LTE-Mare low-power wide-area network(LPWAN) radio technologies that have once been specifiedand standardised in a very short timeframe, in response Moreover, in order to reduce device costs, developersneed to know whichbandshave been deployed by MNOsin territories where they intend to operate. To this end, Since the first deployment of Mobile IoT networks in2017, several MNOs and network providers have gainedextensive insights and experience with NB-IoT and LTE-Mfeatures.This documentwill help to share that experienceand learning with all MNOs, network providers and chipsetproviders deploying and supporting NB-IoT and/or LTE-M. Both technologies are now established withglobalcoverage, enabling application service providers to deployand operate their solutions worldwide in a smooth andpredictable manner. As of Oct 2025 there were more than140 NB-IoT and 129 LTE-M networks deployed. Furtherdetails of these launches can be found at the GSMA’s IoT The Mobile IoT Deployment Guide builds up a pictureof global deployment architectures, from the roamingand interconnect perspective, to realise the benefits Both the mobile industry and its customers benefit fromtheability of devices to roamand to interconnect to allmobile networks. However, each MNO’s setup of NB-IoTand LTE-M frequency bands, data architecture and key —If PSM and eDRX timers were set differently indifferent networks, device and service behaviourwould change, impacting responsiveness to backend-originated commands and the longevity of the battery.—If some (optional) features are not enabled, there could Consistent deployment configuration settings, or atleast transparency on them, are required to achieve acommon deployment experience for IoT developers andusers globally, independent of the MNO network beingaccessed. For any given IoT solution, application logicshould be as constant as possible regardless of which RANis used. From the IoT developer perspective, their devicesneed to work the same way and utilize the same minimum 3. Feature Deployment Emerging features are those that may have some limitedsupport, but it is too soon to know whether adoption ofthe feature will grow further to become widely adoptedor not. For example, LTE-M can su
