It all started with a real problem.

Year 2002. In Argentina, foreign cell phones did not work because the country used a different technology. That’s when HolaSim’s four founding partners —all with backgrounds in mobile telecom— spotted an opportunity

That’s how Phonerental was born — renting fully equipped phones to travelers arriving in the country. Before SIM cards were even a thing, we were already solving one big problem — helping people stay connected.

Over time, we expanded — opening offices in the United States, Mexico, and later across several countries in Latin America. And in 2015, with the rise of international SIM cards, we took a major step — HolaSim was officially born.
