For a typical 7-day trip exploring California's diverse attractions, from Hollywood to Yosemite National Park, a Ti Porto in Viaggio plan with 5-10 GB of data should suffice. This allows for navigation, social media, light streaming, and staying in touch. While public Wi-Fi is available in many cafes and hotels, it's often unreliable, making a dedicated data plan essential for consistent connectivity.
