Bouygues Telecom, headquartered in Paris, is a pioneering French telecommunications provider with a legacy dating back to 1994. As part of the renowned Bouygues group, it stands out for its robust network infrastructure and deep-rooted expertise in mobile connectivity. While Bouygues is a trusted name in France, there is no verified evidence of a dedicated travel eSIM product called "My European SIM." Its reputation is built on reliability and comprehensive service for domestic users rather than unique travel-focused offerings.
