One of the essential things we need while traveling is definitely a strong and reliable internet connection. For our trip in Japan we decided to go for an eSIM from BuddySIM. Traveling across Japan with BuddySIM made everything so easy! From Tokyo’s bustling streets to the serene temples of Kyoto, we were always connected. Whether we were navigating through the crowded Shibuya Crossing or exploring the quieter backstreets of Osaka, the high-speed internet allowed us to instantly pull up maps and guides. There was never a moment where we felt disconnected.

BuddySIM is a highly convenient eSIM provider, ideal for travellers looking for reliable mobile data without the hassle of switching physical SIM cards. Their eSIM plans are tailored to deliver seamless high-speed internet access, ensuring users can stay connected effortlessly.
The main convenience for us was being able to be connected as soon as we touched down in Japan, as you can already activate your eSIM in advance and have it ready to go the moment you arrive at your destination. No more waiting and queueing at the airport arrivals to get a local sim, we could head straight to our hotel to rest after a long journey, being already connected and checking to best way to reach our accommodation on the maps.
BuddySIM‘s offerings for Japan stand out due to their flexibility, making them a top choice for both short-term tourists and long-stay visitors. The available data plans are designed to cover various needs—from light data usage to more extensive consumption—ensuring that travelers remain connected throughout their trip. For instance, BuddySIM offers a 1 GB plan priced at around €9.99, ideal for a quick stay, and a 3 GB plan for €24.99, both with 30 days of validity. These plans come with 4G and 5G compatibility, ensuring high-speed connectivity across Japan, a critical feature for those relying on maps, social media, or business communications. There is also a 20 GB plan for extended usage, allowing travellers to access fast mobile internet throughout their trip without worrying about running out of data. This plan is perfect for those who need substantial data while exploring or working remotely in Japan.

Their services come with additional benefits like zero roaming fees, meaning you only pay for local data rates without worrying about hidden charges.
