What this page covers

Most unlimited eSIMs have a daily high-speed cap.
Bloomy Unlimited Max is designed so you don’t watch caps, throttling or balance.
Pay once; Bloomy manages the data during the term.
Data-only (app calls like LINE/WhatsApp work). Quality varies by network, device and area.

Why “unlimited” can still feel uneasy

Many plans slow after a threshold. A fair-usage policy often sets a daily high-speed cap, and such conditions may be written in the plan details or notes. That’s why “unlimited” can feel slow.

Unlimited eSIM

An eSIM plan you can use without watching data volume — though some throttle after a threshold under a fair-usage policy.

High-speed cap

The amount you can use at full speed per day/term; beyond it, speed may drop.

Fair-usage policy

A common mechanism that adjusts speed for extreme usage so everyone can use the network comfortably.

Who it’s for

Temporary return to Japan

Study abroad / working holiday

Business trips

Travel with video & SNS

Tethering for PC work

Want zero data hassle

These cases may suit another plan

If messaging and maps are enough
If you prioritize the lowest price above all
If several people will tether constantly
If you want it as a substitute for a fixed business line

In that case, a capacity plan or standard unlimited plan may suit you better. See plans

Important notes

*Network quality may vary by area, time of day, device, and local network conditions. If usage far beyond normal travel or stay is detected (e.g., commercial use, prolonged bulk transfers, or excessive multi-device sharing), we may review or temporarily limit the service.

FAQ

Does Bloomy Unlimited Max have a daily high-speed data cap?

Unlike the common “up to X GB/day at high speed, then slower” daily-cap type, it is designed to be easy to use without watching your data on normal travel or stays. Note that connection quality can vary by area, time, device and local network. For usage far beyond normal levels, we may review or temporarily limit communication.
