  Internet of things (IoT) is very much attractive for several sensor based
applications. It provides large coverage of the services with small amount of
resources. Its applications span from the ordinary scenarios such as sensing in
the common digital ecosystem to the far more complicated processes of modern
manufacturing, agriculture, security provisioning, location tracking and health
care. Several types of IoTs have been proposed for the recent applications.
Narrowband IoT (NBIoT) is one of the economical versions of the IoTs. It is a
low power wide area network technology and thus suitable for resource limited
scenarios. In the developing countries, the resources are scarce and economical
solutions are always preferable. Therefore, NBIoT is an attractive solution for
the developing countries. In this article, we present its features and
functions which make it suitable for developing countries. We also provide
several sector based analysis which are suitable for the NBIoT deployment.
