Ease of Access and Pick-Up
One of the biggest advantages is the pick-up process. Located in Terminal 1’s Arrivals Lobby on the 1st floor (06:30-21:00) and Terminal 2 (06:30-23:00), the counters are usually easy to find, especially if you arrive during daylight hours. The process is simple: show your booking, grab the physical SIM card, and you’re set. The physical SIM card means no reliance on eSIMs or complicated downloads, which some travel tech novices will appreciate.
Installation and Connectivity
Installation is as straightforward as inserting the SIM card into your phone. Once in place, your device should automatically connect to Japan’s 5G network, providing seamless internet access. This is particularly appealing for heavy data users—streaming, uploading photos, or using GPS constantly—without fear of extra charges or throttling.
Limitations and User Feedback
However, some users have voiced frustrations. A notable review described a faulty SIM card and the frustration of being told to call a number that they couldn’t reach due to lack of coverage. The review also mentioned slow email support, which can turn a minor issue into a significant inconvenience, especially when you’re in a foreign country and dependent on quick resolution.
The lack of voice call inclusion could be a dealbreaker for those who need to make local or international calls frequently. Although data is unlimited, you might need to rely on Wi-Fi or a VoIP app for calls.
Price and Value
At just over $37, this SIM card is competitive compared to other options, especially considering its unlimited 5G data promise. For travelers who prioritize constant, fast internet, the cost might be justified. But, the non-refundable policy adds a layer of risk; if the SIM is faulty or doesn’t work as expected, refunds are not an option.

Support and Reliability
The negative review about slow help and a faulty SIM highlights a key risk—support quality. Since cancellations are only accepted 4 days prior to pickup, you need to be sure about your plans. If you encounter issues, resolve them promptly, or you might find yourself without internet at crucial moments.
Who Should Consider This SIM Card?

This SIM is best suited for tech-savvy travelers comfortable with troubleshooting and who value unlimited high-speed internet over voice calls. It’s great if your main need is navigation, staying in contact, or uploading media. But if you need reliable support or voice communication, you might want to explore other options or plan to carry a backup.
Practical Tips for Travelers

- Arrive early at Narita to ensure you get your SIM before the counter closes.
- Test your SIM immediately upon installation—preferably in the airport or hotel—to catch any faults early.
- Bring a backup plan; consider downloading offline maps or saving important contacts before travel.
- Be aware of the non-refundable policy, and weigh the risk if you’re already dealing with tight schedules.
- Keep in mind, support response times can be slow if issues arise, so troubleshoot with patience.
- If voice calls are essential, consider supplementing this SIM with a local voice plan or VoIP apps.
