Caught mid-trip in Osaka and need data? For a typical 5-7 day visit, 5-10 GB of data is usually enough to cover your needs. This allows for extensive use of navigation apps (crucial for Osaka's intricate public transport), translation tools, social media, and communication. If you plan on streaming lots of video or making frequent video calls, consider 15-20 GB for peace of mind. With eSIM On Trip, you can get sorted in minutes, ensuring you have the data to explore Shinsekai or Namba without interruption.
