For a dynamic week exploring London, from hiking along the Thames Path to navigating the vastness of the city, we recommend an eSIMAdventures plan with 7-15 GB of data. This robust allowance supports extensive use of navigation apps for finding hidden trails, frequent social media updates from iconic spots like the Tower Bridge, and even some light streaming on long Tube rides. It ensures you're always connected, without needing to hunt for unreliable public Wi-Fi, perfect for the independent explorer.
