The pressure group (or otherwise the Lobby) GSMA said that VodafoneThe Deutsche TelekomThe Orange and five other telecommunications providers have agreed to share mobile location data with the European Commission to track the spread of Coronai. Telecommunication providers, including Telefonica, Telecom Italia, Telenor, Telia and A1 Telekom Austria met earlier this week with EU industry leader Thierry Breton.

Concerns over its use have intensified in recent weeks technology by governments, which aim to monitor those who are in quarantine and detecting cases of coronary heart disease. Concerns arise that the issue of potential privacy violations is being raised, which can largely happen within the scope of state surveillance.
As an EU official said, the Commission will use anonymous data to protect privacy and aggregated cellphone location data, with a view to coordinating measures related to the spread of the Coronation. To alleviate privacy concerns, the data will be erased as soon as the crisis is over, the official said, adding that the EU plan is not about collecting mobile data or policing people.

While the anonymous data do not fall within the scope of EU data protection regulations, the European Data Protection Supervisor (EDPS) stated that the project does not violate its protection rules privacy, as there are safeguards.
According to Reuters, the EU spokesman said in a letter to the EU executive that the Commission should clearly define all the data it wants to obtain and ensure transparency to the public in order to avoid misunderstandings. In addition, the head of the EDPS, Wojciech Wiewiorowski, indicated that it would be preferable to limit the access data to authorized experts specializing in epidemiology, protection and data science. He also warned that these measures could become permanent. The EDPS often stresses that such developments usually do not include the possibility of return when an emergency ceases to exist.

Finally, countries from Singapore to Taiwan and Israel use various methods to combat the spread of coronation, such as smartphone applications for tracking contacts, "electronic fence" based on mobile phones, satellite phone tracking and location bracelets, to ensure that citizens stay at home.
