What to choose between SIM and eSIM?

SIM and eSIM serve the same purpose: one is physically inserted into your phone, while the other is virtual. The downside of eSIM is that, although most modern phones are compatible, some older devices are not. Therefore, it’s important to double-check your phone’s compatibility before purchasing one. What is certain, though, is that eSIM is the future, and traditional SIM cards are becoming less common. Once you've used an eSIM, it’s hard to go back to the traditional SIM card.

Pros and Cons of eSIM in Japan

• You can purchase it from abroad, receive it, and configure it in less than five minutes, so there’s no need to struggle with SIM cards upon arriving at the airport.

• Since it’s not a physical item, there’s no risk of damaging or losing it.

  • Not every phone and device supports the technology.

  Can my phone support eSIM in Japan?

  It’s crucial to verify this before you spend your money! Read our article List of eSIM-Compatible Phones to see if your particular device is compatible.

  While most smartphones manufactured in recent years come with eSIM functionality, not all of them are unlocked. If you bought your phone outright, it’s likely unlocked. However, if your phone was obtained through a contract with a network provider, it’s probably locked to that provider.?
  
  Checking if your phone is unlocked is a quick and straightforward process. If you find that your phone is locked, reach out to your service provider to inquire about unlocking it before purchasing an eSIM. Alternatively, if you’re traveling with family or a small group, consider renting a pocket Wi-Fi device to share among yourselves.

Do I need an unlimited data SIM card in Japan?

If you prefer a hassle-free option, then the unlimited data plan is perfect for you. However, if you mainly plan to use Google Maps and Google Translate while out and rely mostly on hotel Wi-Fi for browsing the internet, then an unlimited plan might be excessive.

Which SIM card offers the best coverage in rural Japan?

When it comes to network coverage in Japan, NTT Docomo is often regarded as having the most extensive infrastructure across the country. However, there isn't a definitive winner when comparing overall quality among the three main providers: Docomo, AU, and Softbank. Recent studies have ranked Docomo highest in terms of general availability, while AU and Softbank lead the race in 5G coverage. Though Docomo is said to have the largest network, its large user base means it may experience slower speeds in crowded urban areas but typically performs better in rural regions.
