Fukuoka eSIM Review 2026: USIMSA for 3 & 4-Day Trips

As I was preparing for my Fukuoka trip,

I made sure to get a Japan eSIM in advance again.

During my Osaka trip, I also used Usimsa

to buy and use a Japan eSIM.

I remembered the data working really well back then,

so for this Fukuoka trip, I didn't hesitate

to choose Usimsa's eSIM again.

Today, I'll organize details about the Japan Fukuoka eSIM price,

how to use it, and my review.

(I'll also tell you how to get a 20% discount!)

​

​

1. Japan Fukuoka eSIM vs. SIM Card

There are many places selling travel SIM cards and eSIMs,

but since I had a great experience using Usimsa's eSIM during my last Osaka trip,

I immediately bought their eSIM again this time.

Once you try an eSIM,

you'll find it hard to go back to a physical SIM card!

When I actually used it in Fukuoka,

the data connected flawlessly not just in the city, but also when I traveled to areas outside Fukuoka like Yufuin and Dazaifu.

I was really satisfied!

One of the things I loved most about using Usimsa

was the ability to use Google Maps and ChatGPT for free, without any data deduction.

​

I actually used ChatGPT a lot during this Fukuoka trip.

​

From checking menus at restaurants and finding tourist spots,

to figuring out transportation, whenever I had a question,

I could just ask and get an answer right away, which was incredibly convenient!

2. Japan eSIM: 3-Day vs. 4-Day Data Comparison

Usimsa's Japan eSIM allows you to choose your travel duration,

from 1 to 90 days, and there are various data capacities available.

The price of Usimsa's eSIM changes depending on the duration you select,

so the most accurate way to check the price is to enter your travel dates when you're actually purchasing.

📌 How to Choose Your Data Capacity

1) 500MB

This is suitable for those who only use KakaoTalk, do simple searches, or navigate with maps.

Recommended for travelers who barely use data during their trip

and rely on Wi-Fi at their accommodation.

2) 1GB

Good for those who occasionally use KakaoTalk, Google Search, maps, and social media.

If you plan on uploading even a few photos,

we recommend choosing at least 1GB or more.

3) 3GB

Recommended for those who frequently use Instagram or other social media, upload many photos and videos,

and occasionally use video calls or watch videos.

If you're traveling with children like me

and occasionally show them YouTube videos on the go,

or if you simply don't want to worry about data usage,

we highly recommend the unlimited plan.

Especially if the price difference between 3GB and unlimited isn't significant,

going with unlimited is a great option.

(In reality, the price difference isn't that big!)

3. How to Use eSIM in Fukuoka and Osaka

Using the eSIM is incredibly simple!

Once you purchase an eSIM, USIMSAR will send you a

QR code for installation via KakaoTalk.

Just tap 'Check eSIM Information' to install, and you're all set!

📌 If you see the phrase 'Pre-installation available in Korea,'

you can install it domestically.

Since the Japan unlimited eSIM is also

pre-installable in Korea,

I installed it in the car on my way to the airport.

Just press the 'Instant eSIM Installation' button,

and it installs automatically – nothing else you need to do!

Wait about 1-3 minutes, and the installation will be finished quickly.

You'll then see the eSIM when you go into your SIM Manager.

Once you've confirmed it's installed correctly, switch it to OFF.

You can then turn it ON once you arrive at your destination.

4. My 4-Night, 5-Day Fukuoka eSIM Experience Review

On my Fukuoka trip this time,

I used it extensively for showing YouTube to my kids,

constantly using Google Maps, and even ChatGPT!

That's why I was so satisfied with choosing the USIMSAR unlimited plan.

I also took photos and immediately sent them to our family group chat,

and checked social media occasionally.

The most convenient part about choosing unlimited data

was not having to worry about monitoring my data usage.

And when you're traveling, there are always those days

when you unexpectedly use a lot of data, right?

You might be fine in the morning, but then suddenly run out of data in the afternoon

if your kids watch YouTube for a long time

or you upload many videos.

That's why I think I'll choose the unlimited eSIM option

again next time I travel to Japan!

The USIMSAR eSIM I used in Osaka was great,

and I used it without any issues in Fukuoka this time too,

not just in the city center but also when visiting Yufuin and Dazaifu.

So, I highly recommend USIMSAR eSIMs!

If the price difference between 3GB and unlimited isn't substantial,

it's a great idea to simply use unlimited data comfortably

rather than trying to conserve it.

You can find out the actual payment amount by entering your travel duration and required data capacity.

So, check the prices according to your itinerary at the link below!
