Journey Japan eSIM Reviews 251

it just works as advertised. speed, latency was good everywhere i visited in japan

My wife and I used JJeSim for our 3 and a half week honeymoon to Japan travelling from Fukuoka, through Kumamoto, Hiroshima, Kyoto, Osaka, Hakone and finishing in Tokyo.

The esim worked amazingly, very easy set up before we left our home country and connected instantly once we arrived. This was very convenient and helped save a lot of stress! We didn't experience any signal loss, apart from some patchiness in deep subways which was to be expected. We both bought 50gb packages and found we didn't use close to this even with constant maps and Pokémon Go!

I have already recommended JJeSim to a family member who was travelling there a week after we returned. We will definitely use it again on our inevitable return trip! The 500 yen discount at Lost Bar is also great! 11/10

JJEsim was super easy to setup when I arrived in Japan and started working immediately! I never had issues connecting unless I was going through a tunnel on the train 😄 outstanding product, worth the price for the peace of mind and stress free experience - couldn't reccommend enough

my first time purchasing and using an e-sim and the whole experience was faultless and very simple. The options and cost were very reasonable when compared to my normal company’s roaming fees and coverage and reliability were exceptional.

I had a great experience! Easy to install and it worked everywhere! Happy to use it again for my next trip to Japan!

Used this eSIM on my first trip to Japan recently, my wife used a different provider through an app, her reception was pretty patchy at times and had a lower data allowance for a similar price.
My jjesim was absolutely faultless, prefect reception everywhere and absolute piece of mind. Highly recommended!

Both me and my partner used JJ Esim throughout our trip. We didn't loose signal once (Tokyo, Kamakura, Kanazawa, Osaka, Kyoto, Wakayama and Hikone) and it was greatly beneficial for our Google map and translation needs.

Used the service when walking the Henro on Shikoku. Even in very remote areas I still had service. I think only twice on a couple of mountains did I lose a connection--and no one on any service had a connection. Would definitely use this again. And really enjoyed the free drink when we got to Lost. All the best.

The service from the esim was great when it worked. I unfortunately didn't have service the whole first day I was in Japan. I was stranded after I was out of range of Haneda airport because I didn't have data. Support got back to me as I sent out an email before I went to bed. This was what I was told "it looks like your eSIM was successfully installed, but you may be running into an activation or data connection issue. Let’s try updating your APN settings, this often resolves connection problems etc. " I was able to get data for the rest of my 2 week trip after with no problems, just a small hiccup. Support also got back to me in under 5 hours.

I had trouble setting up my SIM because of a weird setting on my T-Mobile phone, but after that, everything worked really well. I do wish I could've set up the SIM before I arrived though, because I wasn't able to actually get everything working until I was at my hotel on wifi, if I'd been able to activate it earlier in the states, I wouldn't have needed to navigate without any service from the Haneda.

Also at one point when I left Tokyo via train and got to Osaka it wasn't working, I had to turn it off and on and then turn my other T-Mobile service off for it to work again.

All in all though it worked super well and I'd definitely purchase it again

We cycled through Japan over two months and this Sim was faultless for our planning navigation keeping in touch and communication. Highly recommended!

First trip to Japan. Tokyo, Hakone, Kyoto, Disney. So many options out there but chose this one as enjoy Chris' videos so felt this was a good way to support his work.
The Sim worked well. No issues with purchase install or coverage.
Only problem was in the crush of humanity at Disneysea opening... but everyone seemed to be having issues in the crowd so not a Sim problem.
Will use again!

So easy to install. Arrived at the airport and it was working. No issues using it during my 2-week stay in Tokyo. Would highly recommend!!!

The esim worked without any major issues. It took about 15 mins from exiting my plane in Tokyo for the esim to actually connect but once it did I had just as fast 4G data speeds as I did in the USA. The only downside is the esim is purely data from what I could tell. I was unable to make a phone call or text people using normal RCS, SMS, & MMS. I got around that by using Whatsapp since that uses Internet data to operate. I had a Saily esim running on another phone as a comparison and didn't notice any major differences. I think the Journey esim was slightly faster and held a stronger signal than Saily in some more remote places in Japan that I went to. Overall I would highly recommend this esim

Absolutely rock solid connection my entire time traveling 15 days through 10+ cities all across Japan. Speeds are respectable as well. Not going to be impressing anyone with speed test screenshots, but never once was it slow enough for me to think about it while using it.

Not much to say about it, had internet access throughout the entire 3 week trip. No connection issues at all.

Would buy it again, if the future permits me another trip to Japan.

I used this esim in May/June, had no problem with signal, except deep valleys in mountains, where nobody would have a signal. The speed was ok throughout the whole country. The ordering process was easy and fast. And the cherry on the top, discount in Lost bar

Easy to install, clear guidance, reasonable price, and most importantly of all - I got consistent connection even on the top of a mountain out in nowhere. Cant fault it. I am a very happy customer.

Had a three week vacation, always had good speed and connection. Cities visited during trip: Chiba, Tokyo, Nagoya, Ise, Kyoto and Osaka.

Last time I used airalo, and it was a horrible experience. Especially Japanese sites took forever to load, leaving me stranded when I needed it the most, despite being in the middle of Tokyo. No such issued with jjesim. Heck, it was more stable than my hotel WiFi connection, Definitely worth the slight upcharge. Will definitely use it again next time I'm in Japan.
