日本 プリペイド旅行カード IIJmio eSIM

Connected straight away as soon as arrived. Internet speed is very good +150Mbps.
Had some issues from the beginning as couldn’t do wifi hotspot. Contacted technical support and the issued was fixed.
Used them previously in Thailand trip and South Korea trip. No one beats their price.
Highly recommend them👍🏼

Google Maps worked instantly and directions loaded fast. Very helpful in busy areas.

Setup took only a few minutes and instructions were easy to follow. No issues at all.

Speed was really good even in crowded areas. Maps and translations worked instantly.

Instructions were easy to follow and setup didn’t take long. Worked straight away.

Tried activating too early and thought it didn’t work. Once landed in Japan it connected fine.

Used in Tokyo, Kyoto and Hiroshima. Coverage stayed reliable everywhere I went.

Work fine overall but instructions could be a bit more clear for beginners. After setup, no issue.

No need to find airport SIM or WiFi. Just turn on eSIM and go. Very convenient after long flight.

Used daily for maps, booking tickets and messaging. Connection stable whole trip. Battery drain also not too bad.

Email instructions were clear and setup took just few minutes. Didn’t need to contact support at all. Everything just worked.

Speed was really good in crowded places like Shibuya and Osaka station. No lag when using translation apps or uploading photos.

Used it everywhere from Tokyo to Osaka on bullet train. Signal stayed strong most of the time. Even while moving fast, Google Maps still worked fine which was very helpful.

First time in Japan and first time using eSIM, was a bit unsure but actually very simple. Just scan QR, follow steps, done. If it doesn’t connect straight away, just wait until you arrive in Japan like they say.

Got the QR email within minutes after purchase, which was really quick. Installed before flight and it activated straight away once I landed in Tokyo. Data speed was very fast, even in busy Shibuya area. Used maps and train apps all day no issues.

I’m a bit of a tech dinosaur and accidentally deleted my activation email while waiting for my flight. I messaged Global Starlink on email and they re-sent the QR code through in under ten minutes. Once I landed in Tokyo, the eSIM worked flawlessly. That kind of customer service is rare these days!

Scanned the QR code at Sydney airport and it activated the second we touched down. Used it for Google Maps and Translate constantly with zero lag

Had a bit of a blue trying to activate it at Narita, but the support team on email sorted me out in minutes

Don't bother with the overpriced pocket WiFi rentals at the airport. This eSIM is cheaper and way more convenient. It connected to the local network immediately and the speeds were fast enough

Setup was a breeze on my Pixel—just scanned the code and I was sorted. Only giving 4 stars because I had to manually toggle 'Data Roaming' on to get it working, which I didn't realise at first.

Used this for a solo trip through Hakone and the Japanese Alps. I was worried about losing signal in the mountains, but it stayed strong the whole time

Needed reliable data for Zoom calls while travelling through Kyoto. The 5G speeds were top-notch.

Signal was 5/5 even on the fast trains. I accidentally deleted my activation email, but customer service sent a fresh one within the hour.

Was a bit nervous about the tech side since it was my first eSIM, but it was absolute gold. I had a quick question about when to install it and the support crew on email got back to me in minutes. Once I landed at Narita, it kicked in straight away

Impressive coverage even in the smaller rural towns. The support actually followed up to make sure I was connected properly, which you don't get from big providers. Fast, reliable, and cheap as chips

Very solid performance and easy setup. Only wish the data options were a bit more flexible, but still did the job well.

Coverage was strong on trains and walking around cities. Felt very dependable and good value overall.

No drop outs the entire trip. Used it daily for bookings and Google Translate. Battery usage was very reasonable.

Even in crowded places like Shibuya, data stayed fast. Streaming and navigation worked smoothly. Really happy with it.

Installed before leaving Aus and it activated straight away when I landed. Didn’t have to rely on airport WiFi at all.

Used this eSIM for maps and trains in Tokyo and Osaka. Connection was fast and very reliable. Setup took less than 5 minutes.

Scanned the QR code before leaving Australia and had signal as soon as I landed at Haneda Airport. No queuing for a SIM card or worrying about language. Connection stayed strong across Tokyo and Yokohama. Definitely the easiest eSIM I’ve used.

Used this eSIM in Tokyo, Kyoto and Hiroshima. It activated smoothly and never dropped out. Speeds were excellent for navigation and streaming. Only giving four stars because I felt it could be a bit cheaper, but overall very happy with it.
