Guest User2025-09-11
Upon arriving in Japan, the signal on my phone screen was a silent welcome. There was no rush to remove a SIM card, no anxious scrambling for an outlet. I simply turned on my data connection, and the world quietly unfolded. At that moment, I realized that travel doesn't begin with a customs stamp, but with the moment I connect to the internet.
Walking through the streets of Tokyo, the crowds were packed yet quiet, the neon lights flashed without a clamor. Relying on my DoCoMo eSIM for navigation, I navigated between the unfamiliar and the familiar. From the intersection of Shibuya and the coffee shops of Yanaka's alleys, the signal remained stable, like a constant companion. It was unobtrusive, yet ever-present.
In an electronics store in Akihabara, I snapped a photo of the bustling street scene and immediately sent it to a friend in Taiwan. Under the afternoon sun in Shinjuku Gyoen National Garden, I opened a message and received a greeting from home. In that moment, I understood that the internet isn't just a tool, but a bridge that bridges distances. It allows me to walk through foreign streets while still feeling the warmth of familiarity.
This trip, thanks to the DoCoMo eSIM, I had fewer worries: no need to remember to bring a WiFi device, no need to repeatedly check if my SIM card was lost. Without all that weight, I felt more at ease. I could focus more on seeing the scenery, breathing the air, and feeling the rhythm of Japan.
Travel is never just about reaching your destination; it's about every subtle detail along the way.
And the internet has become the most gentle connection between me and the world.
The DoCoMo eSIM, like an invisible thread, quietly connects me to people far away and the scenery before me.★

This is my second purchase. The signal is strong even in Shangri-La, and I've been able to use it without any problems. I'm going to Kunming-Korea next, so if it works as well as last time, it will be perfect. It's very convenient to be able to use it in other countries without changing the settings. I'll definitely use it again.★

The speed of the 4G and 5G signals is very good. It works without any interruptions. If you try using eSim, you will find it easy, convenient, and economical. You do not need to buy or subscribe to expensive mobile phone roaming packages. You also need to register your identity. We recommend using eSim to complete every trip.
