There are a few ways to get internet in Japan, but an eSIM stands out as the easiest and most convenient option for travelers. Here’s why it’s a game-changer.

What is an eSIM?
It’s a digital SIM card you download straight to your phone—no tiny card to fiddle with! You set it up online, and you’re good to go.

Why You’ll Love It:
・Easy to use for short periods of time
・No need to carry a Wi-Fi router
・No need to insert a SIM card into your phone
・Can be used immediately after purchase
・No risk of loss or theft
・Can be used on hotspots and multiple devices
・Can be paired with a physical SIM card
・No need to pick up or return
・Can be used in low-speed mode once data usage reaches the limit

■Any Downsides?
・Installation can be difficult if you are not familiar with it
・Not all devices are compatible with eSIM cards

All iPhones released after 2018, and most Android phones released after 2022 are compatible with eSIM cards. However, it is advisable to verify compatibility before making a purchase, as some models may not support eSIM cards.

eSIM alternatives include renting a pocket Wi-Fi device or buying a physical SIM card. However, if you opt to rent a pocket Wi-Fi, you will need to pick it up and return it at the end of your trip, and you will have to always carry it with you. You will also need to consider the possibility of the router's battery running out.

If you opt for a physical SIM card, you will need to insert it into your phone, which poses a risk of losing it, as it is quite small. This may also be inconvenient for people who struggle with meticulous tasks. Additionally, if you purchase it online, it may take a while to arrive.

For these reasons, we recommend getting an eSIM when traveling in Japan.

For the simplest eSIM experience, grab one from JP-Pass. Here’s why it’s perfect for first-timers.
