Narrowband IoT (NB-IoT) is a low-power wide-area (LPWA) cellular technology that connects IoT devices over existing mobile networks. Chile was among the first countries in Latin America to experiment with NB-IoT, with early pilot projects (e.g. smart water meter trials in 2017) using the 700 MHz band).
Operators Providing NB-IoT Service
Entel Chile: Entel ensures a commercial NB-IoT network in Chile “between Arica and Punta Arenas” (i.e. from the far north to the far south of Chile) covering all major cities and regions where Entel has 4G coverage.
Movistar (Telefónica Chile): As of 2024, Movistar’s primary IoT offering is an LTE-M (Cat-M1) network, which it launched commercially to serve IoT devices with extended coverage and low power consumption. The coverage spans Chile’s main urban centers, given its extensive 4G footprint.
Claro Chile: Claro (América Móvil) has deployed NB-IoT on its LTE network. Claro’s NB-IoT coverage would correspond to its 4G coverage areas – i.e. available in major cities such as Santiago, Valparaíso, Concepción, and other regions where Claro has network presence.
