WiFi & Sim Cards
Other FAQ's
Staying connected in Japan is easy and important for travellers, whether you need to navigate trains, use translation apps, or stay in touch with friends and family. Visitors can choose from several options: SIM cards, eSIMs, and portable Wi-Fi routers.
SIM cards are physical cards inserted into your phone, offering local data and sometimes calls. They are available at airports, convenience stores, or online, but your phone must be unlocked. eSIMs are a digital version of a SIM card and are perfect for newer smartphones. You can buy and install an eSIM before arriving, giving you instant connection upon landing—no need to swap cards or find a shop.
Another popular option is portable Wi-Fi (pocket Wi-Fi). These small devices create a personal Wi-Fi hotspot you can carry in your bag, ideal for groups or travellers with multiple devices. They’re available for rental at airports or online and often come with unlimited data.
Each option has pros and cons, but all provide reliable access to Japan’s fast and widespread mobile networks. Whether you prefer to travel solo with a SIM or stay connected with friends using a pocket Wi-Fi, there’s a solution to match your needs and budget.
