Very good experience with Smash mobile…
Very good experience with Smash mobile ! I subscribed to a mobile plan for my one-year working holiday visa in Japan. It provided me with a real japanese phone number (essential for your administrative procedures in the country), good internet connection (very fast and with enough data) for a reasonable price. It was perfect for me and helped me a lot since the other mobile plans in Japan are really expensive and difficult to subscribe to when you're a foreigner. The customer service speak english and is really nice and reactive. It was also easy to cancel online once I got back from Japan, since you don't have any contract or cancellation fees. I would recommend it to anyone who need a mobile plan in Japan !

Review Smash Mobile
J'ai passé 1 an avec SmashMobile je ne peux que les recommander. Ils ont été super, un service client hors du commun, des solutions pour les aléas que j'ai pu rencontrer avec mon téléphone. Comparer aux forfaits japonais qui coûtent une fortune et où il faut s'engager pendant au moins 2 ans Smash Mobile ne demande aucun engagement et est bien en dessous des prix avec pour couronner le tout passer par la meilleure ligne japonaise (NTT Docomo).Vous ne serez pas dessus !

The best.
I cannot recommend Smash Mobile highly enough. I lived in Japan for a year, and during that time my experience with Smash Mobile was simply flawless: smooth and painless sign-up, affordable plans with no contract, great coverage and data speeds, and a responsive and helpful customer service department.If you're visiting or moving to Japan, Smash Mobile is hands-down the way to go.

Other than the post office at the airport having a hard time locating the package, everything went smoothly and the SIM card worked well the whole time we were there.

Great experience overall
I had a great experience overall. The setup was pretty simple and I used my phone around Tokyo and get consistent and fast connection throughout my stay. I would say it's well worth the price.

I am really happy about the service !
I am really happy about the service !I ordered my SIM card, and I received it in my mail box only a few days later, with a paper explaining the steps to install it (very easy). Also the customer service is really efficient, they reply very quickly to any question in English or French, so I definitively recommend Smash Mobile.

3Gb sim was perfect for us
We each had a 3Gb sim card for our 11 day trip to Japan and it was plenty for all our needs. It worked everywhere except at the top of the ski runs but that was ok. I'd definitely recommend Smash Mobile

Great Value
I was very happy with Smash! We got our SIM card delivered to the airport a bit at the last second, but when we arrived everything was fine and the SIM card was there.The only improvement I could think of is an email notifying me when the SIM card arrives at the airport, plus the number needed for the post office. Right now, this info could be found under the tracking information, but we had to search for it for a while. 6 GB turned out to be more than enough for our three week trip. We ran Google maps everyday and used the phone as a Wi-Fi hotspot, but we still couldn't use up all the data. Smash offers a SIM for much cheaper than other companies, so I would wholeheartedly recommend!

Really easy process from order to pick up at airport and installing into my phone! Also great value compared to cost of buying at airport. We were in Japan for 3 weeks and 6gb was perfect amount!

Easy, convenient, affordable Data Sim for Japan
Ordering was easy, shipping was very fast and the description, where to pick it up was clear. The price and quality are very good. Also installing was very easy too! (I have an iphone)I am also happy, that I didnt have to send back the sim, because its always a hassle at the airport and if you have to send something back its a bit stressful! I had 3GB for 15 Days. If you are a heavy user of Google maps, Instagram and texting (with pictures and stories) I do recommend 1 or 2 GB more. I ran out of data 2 days before I left. Top up is quite expensive so I suggest to order enough data.Oh and if you want to check your usage, you would have to do that in your data settings on your phone.Overall the experience was wonderful! No issues at all.

Service was great
Service was great! Value is great! However, after a certain amount of time where you are using a lot of data, the data gets throttled.

No calls but 4G works fine
Was unable to make any calls but 4G worked fine! It was a little hard to set up as you need wifi Connection to do so. Would be useful to know that beforehand. Overall happy with the service! I would use it again.

Service was good, and no problems with the card
Good, no problems. The settings did take some effort but overall it shouldn't be too difficult for most people.

a bit expensive but reliable service
You get what you ask for. In a Samsung Galaxy S9 dual sim it worked like a charm after putting the appropriate APN settings. SIM was delivered by a mailman in three days after placing the order.

Easy to use
Easy to use, especially after I had an issue with having to change airports due to a missed flight they bought the sim to my hotel which was amazing service!!!
December 10, 2019
Easy ordering process and delivered to my home address in plenty of time before I flew out. The setup instructions could have been little more detailed as the instructions did not reflect the android version I had but I figured it out. Flawless connection whilst out in Japan, no reception issues in the 8 cities invisited. Definitely recommend this SIM card for hassle free travel.

Super SIM card
Super SIM card ! The SIM card was very powerful and worked very well. The company is also very listening and helpful. The Internet works very well everywhere in Japan. I traveled in the country and it has always worked.

Simple, Efficient, Always Available !
Simple, Affordable, Efficient, Always Available !The information on the website is very detailed and clear, so it was easy to see that Smash mobile plans are really affordable compared to other Japanese Mobile plans !The delivery of the SIM Card is very easy and trustworthy, and the payment method is perfect for someone like me who doesn't have a japanese banck account.But what I appreciate and like the most about Smash Mobile is the messenger contact, which is really great in order to answer to all your questions, you get a reply within 10 mns !Smash Mobile is the best choice in my opinion, I highly recommend it !A little feedback though, it would be even greater to be able to follow-up your data or calls consumption by yourself, without having to ask on the messenger app.Other than that, great job Smash Mobile, and thank you !! 🙇‍♀️

Being our first trip to Japan
Being our first trip to Japan, we were worried about being able to get internet while we were there. Smash Mobile made everything super easy! Communication was fast and easy. The WiFi was sent to me at the airport with easy pick-up. We traveled from Hiroshima to Tokyo with many stops in between over a 2 week period. Our signal never dropped. I cannot recommend them enough! Thank you!
