Many travelers visiting Japan are looking for an eSIM that allows them to stay connected. While some eSIM plans are labeled as "UNLIMITED PLANS," it is important to note that eSIMs offering unlimited high-speed data in Japan come with a Fair Usage Policy (FUP). This means that high-speed data is not entirely unlimited.
Before purchasing an unlimited eSIM plan, it's important to understand two key points:
Many travelers seek eSIMs that offer unlimited data, but in reality, most people find that 1GB of data per day is more than enough for their smartphone needs. If you have an eSIM plan that allows around 2GB of data per day, most users will be able to enjoy data services without worrying about speed restrictions.
Telecommunication companies share a limited bandwidth among many users. If a small number of users were to consume a large amount of data continuously, it could slow down the network for others. The FUP is designed to prevent this from happening.
Unlimited plans can easily become unfair due to the excessive data use of a small number of users. By limiting the speeds of users who exceed a certain data amount, telecom companies ensure a fair balance between heavy users and regular users.
Operating telecommunication infrastructure, such as base stations and networks, involves significant costs. If truly unlimited plans were offered, these costs would skyrocket due to the need for constant infrastructure upgrades and maintenance. The FUP helps to control excessive usage and manage costs.
The FUP ensures that all users can enjoy a stable and fair network environment. By applying speed limits to users who exceed certain data thresholds, other users can continue to enjoy a good quality of service.
Some heavy users consume large amounts of data for illegal downloads, streaming, or other commercial activities. The FUP is applied to discourage these behaviors and ensure the network is used responsibly.
