58 reviews for Japan 5G SIM Card
Smooth transaction, quick delivery and great communication. Arrive with great packaging and instructions.
I placed two orders (30gb and 10gb) on 21 Nov 2022. The 30gb was received on 1 Dec. The 10gb SIM card hasn’t came but the tracking number given by Travelkon shows it was delivered to NSW on 3 Dec, while I’m located at VIC.
I contacted Travelkon, they explained the barcode scanned may be incorrectly and asked me to wait till Friday (9 Dec) to see if it will come … Then, I spent a week checking on my mailbox, nothing come though. Travelkon said will arrange another SIM and now I’m waiting for the mail again.
The communication with Travelkon was not really instantly, I have to keep follow up with them. I hope there’s no problem on using the SIM card during my trip in Japan.Five staring rating for this order. My 30GB SIM card was dispatched on 27 Nov and arrived on 1 Dec. But my other order (10GB SIM Card) was not arrived and now waiting for another one to come.
My order was not delivered. After reaching out to customer service the best they could do was to add a discount to my next purchase. Although it is a frustrating outcome, the fault doesn’t lie with travelkon. The customer service has been of great assistance in replying within a day and being professional about the issue. I’ll make another review on how the SIM works out when I use it.
Didn’t actually provide usable data. Only 3G network. I replaced it with an eSim after a day
Hi Rob
Sorry to hear your experience, however please note that we sold thousands of these SIMs without any issues. If the data stopped working the settings must not be correct.
We ask customer to please review the guide or contact us to troubleshoot. Have you contacted us regarding this issue?
Worked as soon as I installed when I arrived in Japan
SIM was posted an arrived quickly. It worked in Japan but I had to manually set the network operator per the included instructions because it didn’t work “out of the box”. The biggest problem is the SIM I received appeared to actually have been some kind of prepaid Taiwanese SIM on roaming mode, which meant that I appeared to be coming from Taiwan for all internet traffic. This meant that web searches would default to Taiwanese results rather than Japanese results, some Japanese websites refused to load entirely (e.g. someone sent me an online voucher for a drink at Starbucks Japan and I couldn’t open it), and sometimes my online payments were rejected (I told my bank I would be in Japan not Taiwan so I guess they flagged some of my transactions as suspicious). Other travel SIMs I have used in Japan did not have this issue and the internet traffic would appear from Japan. TravelKon should be more transparent about this fact as it could cause similar problems for others.
Finally, sometimes when travelling between prefectures the SIM card would stop working and I would need to toggle flight mode on/off to make it work again – just something to be aware of.
I was a bit dubious when my unmarked SIM arrived in a zip lock bag with minimal instructions, but I put it in my phone on arrival in Japan, it started working within a few minutes and I had no problems at all throughout our stay. Would definitely recommend and use again.
Hi Alison we ran out of our normal packaging usually it’s much nicer packaging with detailed instructions. Glad it work out fine for you thank you for the feedback ????
No reception most of the time.
There is a known outage which is affecting the signal, if you haven’t already please contact us for a partial/full refund (depending on usage).
We sincerely apologise for the inconvenience
I bought two sims for my wife and I during our three and a half week stay in Japan. We were able to prepare the sims prior to arrival and following the simple instructions, we had the the sims up and running whilst our plane was still on the tarmac. The initial connection took around 4 or 5 minutes. We travelled from Fukuoka right across to Tokyo and always had great service. Very satisfied with the value and service derived from these sims. Wouldn’t hesitate to recommend or use again.
We bought five 10GB sim cards and it was perfect for our trip. We only had issues with one of the cards after a few days of use, but TravelKon were easily contactable and replied very quickly through whatsapp. They sent through an eSIM as a replacement after some troubleshooting. Great service all round!
Best travel sim and great support if you encounter any issues
Great value and easy to use when travelling overseas!!!
Quick and easy service at a very competitive price. Would buy again!
I purchased the card which is recommended by my friend who said with good experience. Customer support is good and efficient.
Unfortunately due to recently discovered health problems we cancelled out trip to Japan and would not be able to use your card.
Speedy delivery ! The SIM card worked like a champ in Fukuoka !!
Activation process was not smooth, as my SIM card was not initially loaded properly, and when I ordered a japanese sim card i got a taiwanese one that gave me taiwanese google search suggestions
Customer service is excellent! I stuffed up my address and they immediately contacted Aus Post and sorted it out.
Easy to use and very convenient just as per description 10/10 recommended!

The sim card wasn’t activated when I got to the country, but the tech support I received resolving the issue was very strong considering it was a Sunday night.
Super easy to use – started working immediately and had great connection throughout the trip.
Fast delivery. Support is very prompt. Thank you
This is my second order from Travelkon, team was very helpful and they dispatched my order next day.
Easy use, Perfectly working!
reported the sim card yet received although AUSTPOST said delivered. TRAVELKON promise resend the sim card and investigate with austpost. That is good attitude to deal with client.
I’ve got the sim card before travelling to Japan. Very easy to installed. It worked everywhere. Very reliable and lasted all my trip (3 weeks) with spare data to use. I Strongly recommend it.
Very easy to use. Pleased and would buy again. Reception was great in rural Japan where I travelled. No issues at all. Instant reception once I landed.
Same comment as above
My sim card arrived within a week of ordering it. In the meantime I was sent specific and very easy to understand instructions. I will be activating it when I arrive in Japan in 2 days time. All being well, I will be ordering from them in the future.
The SIM worked perfected upon our arrival in Tokyo. Good value SIM.
Good customer service
Great service.
Great service
Provided the sim works well in Japan, delivery and ordering were prompt and instructions included.
The whole selection and purchase experience was exceptional. Had a perceived problem with a discount code and the response from customer service was immediate. This was a surprise as it was late at night and I didn’t expect a response until business hours.
Super Fast delivery and great instructions, thanks!
Great
Amazing fast customer service and great connection throughout Japan. Highly recommended
It was expensive for the amount of data
Working well as soon as I landed. Thanks!
Went to Japan and realized sim wasn’t working to talk back and forth to customer service for an hour for them to work out after an hour they send an expired SIM card as we were in Japan. Thank you to customer service for helping.
Seems to be as advertised. Have yet to use it.
Bloody awesome, arrived 2 days after placing order. Second time we’ve used this provider and have no reason to not use them again in the future
Worked as soon as we received reception, and for 2 weeks
fine. Great for maps and translation. Also on Cruise boat whilst in port and within reasonable distance of land.Great service. Applied a discount and refunded me after I had completed the purchase.
Great deal with no fuss. Thanks!
we purchased this a few times already, always good and no issue. thanks
