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 of the People's Republic of China|National Intelligence Law] and the Cybersecurity Law of the [People's Republic of China|2016 Cybersecurity Law], the research noted concerns about potential state surveillance.
