Unlimited Max conditions

1. Slowdown by data used

Unlimited Max has no slowdown based on how much data you use. Normally, if you use up your data, more is added automatically.

2. Fair use

To keep usage fair, extreme usage may be limited.

3. Extra payments during the term

Bloomy manages the data during the term, so you are not asked for extra payments.

Speed changes due to signal conditions or congestion can happen on any network.

*Based on how the service is run as of 12 October 2026. Conditions may change.

How it differs from other unlimited eSIMs

Fixed data

The amount you can use during the term is set in advance. After it runs out, the connection stops or slows down depending on the plan, or you buy more.

Unlimited plans with a set daily high-speed amount

The plan sets how much you can use at high speed each day, and past that the speed drops for the rest of that day.

Unlimited Max

There is no daily high-speed cap. There is no slowdown based on how much data you use. Normally, if you use up your data, more is added automatically. To keep usage fair, extreme usage may be limited.

The three types and the conditions of each plan (countries, days, total price, what happens after the daily amount, tethering, start of the term) are compared in our guide to unlimited eSIMs.

What this page covers

  • Most unlimited eSIMs have a daily high-speed cap.
  • Bloomy Unlimited Max is not a daily high-speed cap plan; Bloomy manages the data during the term.
  • There is no slowdown based on how much data you use. To keep usage fair, extreme usage may be limited.
  • Data-only (app calls like LINE/WhatsApp work).

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.

What Bloomy Unlimited Max solves

No slowdown by data used

There is no slowdown based on how much data you use.

Bloomy Unlimited Max is available on single-country plans for 184 countries and regions, plus 25 multi-country plans (counted from our plan list; last checked: 2026-10-26).

Validity 1〜365 days 1 to 180 days (choose the number of days) 1 to 30 days (choose the number of days)
After the limit Depending on the plan, data stops or slows. Speed may drop after the daily allowance. The throttled speed differs by plan. Unlimited Max has no slowdown based on how much data you use. Normally, if you use up your data, more is added automatically.
Extra purchases Plans that support top-ups can be topped up from My Page (varies by plan). Whether you can top up depends on the plan. No extra payments are requested during the term.
Fair-use conditions The total data amount is the limit. Governed by the provider’s fair-use policy. To keep usage fair, extreme usage may be limited.
Suited to Trips and stays where you can estimate usage, such as maps, messaging and searches. When daily usage is predictable and you want to choose the number of days. When you want fewer balance checks and top-ups, and to use video as well.

Who it’s for

Temporary return to Japan
Study abroad / working holiday
Business trips
Travel with video & SNS
Video meetings and online classes
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

  • Data-only eSIM. No phone number, SMS or voice calls (data apps like LINE work).
  • Availability differs by country/plan and rolls out gradually.

*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.
