Japan Data ONLY SIM Card 15 Days | Unlimited Internet Data (10GB at 4G LTE High Speed Data Then downgrade to 128kbps) |Docomo KDDI Network | Hotspot tethering Supported

Great! My phone is old and isn't compatible with eSIM. So this SIM card worked perfectly for a 2 week trip to Turkiye, Italy, and Poland. I followed the instructions on the packet, and I had to use one of the troubleshooting tips to get it to work (just had to restart the phone, then it worked). It worked great. Would buy again. Thank you!

Update April 5,2023After 2 days, the remaining 2 (30 day 15G SIM card) that initially worked also got disconnected and China Mobile shows up as the network. I know I did not use up the 15G of data because I got an eSIM from SingTel Airalo, and I used 500M in 2 days on the SingTel network. I am lucky that I still have a slow cell data service and have international data. Albeit at the unbearable speed of 256kb. It was my life line to get the Airalo data service that delivers eSIM card online.If you have to use a physical SIM card, get the 15 day ones and not the 30 day ones. The 15 day SIM cards worked all the way to the end of my trip.Original review …The SIM cards worked like a charm when they do. I bought 6, installed 4. 2 worked on power up. Good. Not the same for the other 2. The other 2 connected briefly and got kicked off. “iPhone not activated Contact you carrier if this problem continues to occur”. It looked like to me that the SIM card is not authorized to work in Japan. So I checked the carrier. And it says China Mobile (in Chinese). Of course these 2 wouldn’t work! It would work in China! So this is a packaging problem. They we mixing up SIM card from the wrong country! Luckily, I bought two extra as backups. The other backup SIM cards (15 day 10G) worked just as expected.

My daughter studied abroad in Paris for 4 months. This esim card saved us so much money. Easy to install and she had zero issues with calls, texts or email. Well worth the money

We bought this Sim card for our recent trip to Japan (April 2025). It has excellent connectiviy in all the regions we visited (Osaka, Kyoto and Tokyo). Just change your sim card prior your arrival to Japan. Speed is good for Google Maps, Whatsapp messages, Google Translate and Social media apps. Recommended

Make sure you are in a strong WiFi spot when you insert it, that you have an unlocked phone and that roaming is turned on in your settings. Worked well in French Alps. Worked well with WhatsApp.

Easy to set up, clear pre-arrival instructions, and worked solidly as expected.

I bought 2 of these card to use for when I took my first trip to Europe. Was greatly disappointed with the cards because I could only get very little internet connections anywhere that I traveled. Visited multiply countries and was the same in all. Made it very difficult to navigate as you can imagine. Used them both on iPhone 11 and 13 with the same issues. Will never purchase these again

On my last visit to Japan, I struggled to get my iPhone to work. My carrier in the US doesn't offer service in Japan so it was a challenge to make calls and text home. I won't bore you with the details of the issues I encountered but rather I'll just tell you how this SIM card solved my problem.I got an idea when I purchased my JR Pass and they offered me a pocket WiFi device. They'd charge $63 for seven days, 3gb data limit per day at 4G speed before it's throttled to 256k. Not bad, but it was a hassle to get and return the device. Limited locations. Poor hours. Late penalties. Lose it, pay for it ($140).I figured I could use an old unlocked Android phone as a portable hotspot. I bought this SIM for around $20, put it in the phone, and turned on data roaming. After a minute or two, it connected.I burned through the 10gb of high speed data in the first two or three days, then used it at 128k. It worked great with my devices. Using a VPN and WiFI calling on my iPhone 15, I was able to receive and make calls and texts using the old Android phone as a hotspot, and I didn't have to worry about running out data. I only used it for a week but it would have lasted fifteen days. It worked fine in Tokyo, Kyoto, Hiroshima, and Hakodate. At 128k, for websites it was very slow, but no problem with calls and texting.
