A typical 5-7 day trip to Barcelona usually requires 3-5 GB of data. This is ample for navigation with Google Maps, checking public transport (TMB app), social media, light browsing, and messaging while exploring neighborhoods like Eixample or Gràcia. If you plan to stream videos or work remotely, consider 10 GB or more.
