For a 3-7 day adventure exploring both urban and natural landscapes around San Francisco, we recommend an eSIMAdventures plan with 7 GB to 15 GB of data. This allows for extensive use of offline-capable mapping apps like AllTrails or Gaia GPS (with occasional online sync), checking weather forecasts for your hike up Mount Tamalpais, coordinating with fellow explorers via messaging, and sharing your epic vistas from Lands End. Consider more if you plan to upload high-resolution videos or tether other devices.
