Japan SIM

My son-in-law recommended I buy a SIMCorner 30 day unlimited data SIM for my 3 week Japan trip. He had been impressed with the one he had bought for a recent business trip. I’m still on my tour & can say I’m so pleased I followed his recommendation. The coverage has been excellent. Very useful to be able to access Google maps & keep in touch with family & friends at any time. It has worked out cheaper than using global roaming with my Australian telco.

Easy to use data Sim for Japan.

Was my first trip ever traveling to Japan with my 10 year daughter. With all the research on Sims and data Sims I decided to go with Sim Corner. It arrived very fast and instructions were very clear. You choose when to activate the Sim on any given date, so I activated mine the day before I left for Japan. When I arrived it was working perfectly and worked well the whole 21 days I was there. This was very handy as I needed it right away to use google maps to navigate my way around.Already planning another trip and I'll be getting the same Sim from Sim Corner for next time.Highly recommend.John.

Data Coverage Everywhere!

Easy to setup and activate. The coverage is literally everywhere - at the top of a mountain, rural villages, and etc.

Japan Unlimited

Had some initial problems getting the Sim activated via the QR code but this was quickly resolved following an email to customer support. (Would be better to include manual instructions on setup in the pack) Worked perfectly throughout Japan and would use again in future.

Great service & would use again

I bought an unlimited data sim for my trip to Japan (4wks). I was so glad I had unlimited data as I didn’t have to worry about running out of data during my trip. There was no daily limit either. I think my most used apps were Translate & Google Maps, plus backing up photos to the cloud & using Hotspot on my phone to my iPad when I needed data for that. I needed a bit of help from Support at Sim Corner initially & they provided support very promptly which was much appreciated!

SIM Corner unlimited 30-Day Japan SIM

I purchased an Unlimited 30-Day SIM for our Japan holiday. We travelled to Tokyo, Lake Kawaguchiko, Kamakura, Kanazawa, Takayama, Kyoto, Himeji, Hiroshima, Miyajima and Osaka. The SIM worked perfectly.

Great value for money

I had trouble with the setup and removal once home - the online support was fantastic, rapid response, clear instructions (not too wordy). Once installed the sims all worked seamlessly and in Japan were very needed as most of the accommodation WiFi is unsecured and slow. Will definitely use SIM Corner again. This is my third trip using this’d service and has not disappointed. Good value for money. Weather and Google Maps all worked brilliantly.
