History

Holafly was founded, in Murcia, Spain, in 2017 by Pedro Máiquez and Yingyan Hu. [1] [2]

In 2019, Holafly joined the Lanzadera accelerator program. [3] With the help of this program, Holafly expanded its products to include eSIM services in countries such as Germany and France. [1]

eSIM

Holafly was an early adopter of eSIM technology and provides unlimited prepaid data and roaming plans to international travelers in over 190 countries. [3] [4]

The Holafly app, which is available on iOS and Android, [5] helps monitor a user's data usage. [4]

Ritoban Mukherjee, writing in a review for TechRadar , described Holafly's onboarding process as "user-friendly" and its support as "excellent". [4]

Controversies

In August 2025, Holafly was mentioned among other travel eSIM providers in independent research examining potential security risks associated with eSIM technologies. A study, presented at the USENIX Security Symposium, found that traffic from Holafly eSIMs was sometimes routed through Chinese and other undisclosed networks. In light of Chinese legislation, such as the 2017 National Intelligence Law (Article 7) and the 2016 Cybersecurity Law (Article 28), the research noted concerns about potential state surveillance. [6] [7]
