To maintain their leadership positions in their respective markets in such a competitive industry, CIMA and HOLA AMERICA need to constantly innovate their products and services, taking advantage of the benefits of new technologies. To help them in this purpose, Nexos Software designed and built mobile applications on different platforms that innovated the way to connect national and international long distance calls, since it was possible to dispense with physical calling cards, simplifying the process of making a call for users of both brands. As a result, their customers were able to use long distance connection services from their cell phones by dialing transparently to international and domestic destinations, without using the tedious traditional process of dialing access numbers and providing PINs, which has given a boost to the image of both brands with their respective customers.
