My trip to Japan last October was memorable for its sense of total immersion. Every day was different: a Shinkansen ride in the morning, museums and old-town streets in the afternoon, and dinner in the evening at a small restaurant with no English menu. Sometimes I had to improvise, especially with navigation and communication. In such moments, my mobile phone service was a lifesaver. I used Mobal’s Japan SIM because it came with a real Japanese phone number https://www.mobal.com/japan-sim-card/ , which proved convenient. The trip was stress-free: everything worked, I was always connected, and I could focus on what mattered most—my impressions and the road.
