Bloomy eSIM is a data-only eSIM you can use for travel, study abroad, long stays and trips back home. Many people assume that a carefully run service must come at a premium, but when you line up the actual listing prices on a like-for-like basis, many Bloomy plans come in lower than the major global eSIM services. Depending on the country and data amount, some plans land at roughly a third to under half the price of other providers (this does not mean Bloomy is the cheapest for every country or every plan).
- Many Bloomy eSIM plans are priced lower than major global services
- For some countries and data sizes, you may pay roughly a third to under half of what others charge
- Prices move with exchange rates, stock and promotions — always check the latest before buying
- No phone number, SMS or voice calls; app-based calling (WhatsApp, etc.) works over data where coverage allows
- When choosing, also check data amount, speed/fair-use limits, data-only status and device compatibility
This article organizes listing prices as of the survey date (June 2026) so you can compare providers under conditions that are as close as possible. Beyond price, it also helps you check the points that are easy to overlook behind a low number — speed/fair-use limits, data-only status, and device compatibility.
The short version: Bloomy eSIM isn't a "pay-more-for-peace-of-mind" service — it's a clear, easy-to-choose, low-priced data-only eSIM. Comparing data plans on a like-for-like basis, some countries and data sizes come in at roughly a third to under half the price of major services. Prices do move with exchange rates, stock and promotions, so it's worth confirming the latest figure at the moment you buy.
Many Bloomy eSIM plans are priced lower than major services
It's easy to assume that a well-supported service must cost a little more. But when you place the actual listing prices side by side under the same conditions, many Bloomy eSIM plans come in lower than the major services. For some countries and data sizes, you'll find plans at roughly a third to under half the price elsewhere. That said, Bloomy won't be the cheapest for every country or every data amount. That's exactly why the surest approach is to decide your destination, data amount and number of days first, then compare.
- Prices, data amounts and validity are laid out clearly so they're easy to compare
- It's easy to find a right-sized plan based on the data and days you actually need
- Data-only (no phone number or SMS, as a rule). An eSIM-compatible device is required
Why eSIM prices vary so much between services
Even for the same country and the same data amount, prices can differ widely between services. Some people worry that "too cheap" means low quality, or assume "more expensive must be better." In reality, most of the gap comes not from quality but from how each product is designed and what conditions apply. The main reasons:
- How data sizes and validity periods are tiered (strong on small/short plans, or on large/long plans)
- Differences in speed limits, fair-use policy (FUP) and tethering conditions
- Whether the lineup is built around unlimited plans or around capped data plans
- Movement from exchange rates, promotions and stock
- Support languages and the level of after-purchase help
In particular, unlimited plans and standard capped plans rest on different assumptions, so they can't be compared one-to-one. As a rule, this article compares capped data plans on a like-for-like basis and treats unlimited plans separately. Looking past the headline number to what that number actually includes (whether there's a speed limit, whether tethering is allowed) lets you choose with confidence.

eSIM price comparison for South Korea (popular for short trips)
South Korea covers a wide range of use cases, from quick two-to-four-day getaways to stays of about a week. If you mostly use social apps, maps and translation, a small-to-mid plan is often enough — which makes price differences easy to feel here.
| Data / Days | Bloomy | Saily (official) | Approx. ratio |
|---|---|---|---|
| 1GB / 7 days | ≈ $1.06 | ≈ $3.99 | about 1/4 |
| 3GB / 30 days | ≈ $2.68 | ≈ $8.99 | about 30% |
| 5GB / 30 days | ≈ $4.06 | ≈ $10.99 | about 37% |
| 10GB / 30 days | ≈ $6.99 | ≈ $18.99 | about 37% |
| 20GB / 30 days | ≈ $12.23 | ≈ $29.99 | about 41% |
* Listing prices as of the survey date, shown in USD for reference (1 USD = 160.275 JPY). Check other providers' official pages for the latest. Holafly's unlimited plans are covered separately.
eSIM price comparison for Canada (for study and long stays)
Canada is a common starting point for longer stays such as study abroad or a working holiday. An eSIM works well as a bridge — keeping you connected for the first few days after arrival until you sign up for a local plan.
| Data / Days | Bloomy | Saily (official) | Approx. ratio |
|---|---|---|---|
| 1GB / 7 days | ≈ $2.18 | ≈ $5.29 | about 41% |
| 3GB / 30 days | ≈ $5.55 | ≈ $12.99 | about 43% (under half) |
| 5GB / 30 days | ≈ $8.49 | ≈ $17.99 | about 47% |
| 10GB / 30 days | ≈ $14.72 | ≈ $30.99 | about 48% |
| 20GB / 30 days | ≈ $24.96 | ≈ $43.99 | about 57% |
* Listing prices as of the survey date, shown in USD for reference (1 USD = 160.275 JPY). Airalo's Canada plans should be checked on its official sales page, so they're omitted here. Holafly's unlimited plans are covered separately.
eSIM price comparison for the United States
The US covers a broad mix of business, leisure and study, and trip lengths vary a lot from person to person. Longer stays tend to need more data, so the trick is to match the data amount to how you'll actually use it.
| Data / Days | Bloomy | Saily (official) | Approx. ratio |
|---|---|---|---|
| 1GB / 7 days | ≈ $1.25 | ≈ $3.99 | about 31% |
| 3GB / 30 days | ≈ $3.43 | ≈ $8.99 | about 38% |
| 5GB / 30 days | ≈ $4.93 | ≈ $13.99 | about 35% |
| 10GB / 30 days | ≈ $8.98 | ≈ $21.84 | about 41% |
| 20GB / 30 days | ≈ $17.22 | ≈ $35.13 | about 49% |
* Listing prices as of the survey date, shown in USD for reference (1 USD = 160.275 JPY). Saily's US 10/20GB figures may reflect a promotional price, so the regular price can differ. Airalo's US plans should be checked on its official sales page. Holafly's unlimited plans are covered separately.
(Taiwan: Bloomy eSIM did not offer Taiwan plans as of the survey date. Since a Taiwan comparison would cover other providers only, it isn't included here. Check the comparison page for the latest list of supported countries.)
Three things to check alongside the price table
Choosing on price alone can leave you thinking "that wasn't enough data" or "this didn't fit how I use my phone" once you're there. When you read a comparison table, check these three points too.
1. Does the data amount fit how you'll use it?
If you mostly use maps, messaging apps and web search, a small-to-mid plan is often enough; if you watch a lot of video or tether frequently, a larger plan or an unlimited plan suits you better. Rather than "1GB because it's cheap," aim for "enough data, at the lowest price that covers it." There are data-size guidelines in the eSIM guide as well.
2. Speed limits and fair-use conditions
Speeds may be limited once you pass a certain amount of usage. Even unlimited plans can come with a fair-use policy or tethering conditions, so think of them separately from capped plans.
3. Data-only and device compatibility
Bloomy eSIM is data-only. You'll need an eSIM-compatible, carrier-unlocked device, so it's worth checking compatible devices before you buy.
Compare unlimited plans "separately"
Unlimited plans like Holafly's rest on different assumptions than capped plans, so they can't be compared one-to-one. Unlimited suits people who don't want to think about how much data they use, or who watch a lot of video on a short trip, and it tends to cost more than a capped plan. Note too that even unlimited plans may carry speed limits, a fair-use policy or tethering conditions — so "unlimited" doesn't necessarily mean unrestricted no matter how much you use.
Bloomy eSIM also has unlimited-style plans (such as Unlimited Max), but since they serve a different purpose, it's best to consider them apart from the capped-plan price comparison. To decide whether unlimited is right for you, see the unlimited eSIM explainer and the Unlimited Max page.
Why Bloomy eSIM is affordable and easy to choose
Compare by destination
Pick a country or region and see that destination's plans in one list. Because the right choice changes depending on whether your trip spans multiple countries, narrowing down by destination first is the quickest path.
Choose by data and days
Find a right-sized plan from the combination of data and days you need. The lineup makes it easy to match small data for short trips and mid-to-large data for longer stays.
Buy just what you need
From small/short to large/long, you can choose to fit your use. It's easy to arrange just the amount you need, including options if you run short.
Check prices on the web
You can review prices and conditions on the web before installing any app, so you can move forward only once you're satisfied.
Clear and easy to navigate
Listings and support are designed to be clear and easy to follow, even for a first trip abroad. If you get stuck, the FAQ and setup guide are there to help.
What to watch for when choosing a low-cost eSIM
Will the data be enough?
How much you need depends on how you use your phone — maps, social apps, video and so on. It helps to check a rough guideline for short trips too.
Are there speed limits?
Speeds may be limited once you pass a certain amount. If you'll use a lot of data over a long stay, check the conditions first.
Conditions on unlimited plans
Even unlimited plans can come with tethering or fair-use conditions. It's important not to assume "unlimited" means no restrictions at all.
No phone number or SMS, as a rule
Bloomy eSIM is data-only. If you need a phone number, SMS or voice calls, also consider a plan that includes a number, a local SIM, or pairing it with a VoIP / virtual-number app. App-based calling such as WhatsApp can work wherever you have a working data connection.
Is your device compatible?
You'll need an eSIM-compatible, carrier-unlocked device. Some older or budget phones aren't supported.
Compare prices on Bloomy eSIM
If you already know where you're going, enter the country, data amount and number of days on the comparison page to compare plans at the latest listing prices. Prices are updated weekly and move with exchange rates and promotions, so confirming the latest figure at the moment you buy is the most reliable approach. Keep in mind that real-world connection quality varies with the local network, your device and the area you're in.

Summary
Bloomy eSIM isn't a "pay-more-for-peace-of-mind" service — it's a clear, easy-to-choose, low-priced data-only eSIM. Comparing capped plans on a like-for-like basis, some countries and data sizes come in at roughly a third to under half the price of major services. That said, prices change, and Bloomy isn't necessarily the cheapest on every plan.
When choosing, look beyond price to "will the data be enough," "the speed/fair-use conditions," and "data-only status and device compatibility" to avoid surprises. Start by deciding your destination, data amount and days, then compare prices on the comparison page.
