eSIM Doesn't Have to Be Complicated
If you've never heard of eSIM before, that's fine. This guide uses plain language, no tech jargon, and tells you exactly what to tap on your phone.
The short version: An eSIM is like a digital SIM card. Instead of putting a tiny chip in your phone, you scan a code and your phone connects to the internet in Japan. That's it.

Should You Use eSIM or Pocket WiFi?
| If You... | Choose |

| Have an iPhone XS or newer | eSIM โ follow this guide |
| Have a newer Samsung or Pixel | eSIM โ follow this guide |
| Don't want to touch phone settings | Pocket WiFi โ read this instead |
| Have an older phone | Pocket WiFi |
| Travel with a partner who's tech-savvy | Ask them to set up eSIM for both phones |
Honest advice: If phone settings make you anxious, pocket WiFi is fine. It's more expensive ($35-70/week vs $13) but requires zero phone configuration โ you just connect to a WiFi network.
