What to Expect When Using the SIM Card at Narita Airport
Starting with the pickup process, travelers can easily find the counter in the 1F Arrivals Lobby of both Terminal 1 (06:30-21:00) and Terminal 2 (06:30-23:00). It’s a straightforward process—just stop by, pick up the SIM card, and you’re ready to install. The manual included helps guide you through the simple process of inserting the SIM into your phone, which is generally quick and fuss-free.
Once installed, you’ll enjoy unlimited 5G data, which is a major plus, especially for those who need fast, reliable internet for maps, streaming, or staying in touch. The seamless connectivity means you won’t have to worry about data caps or throttling—just use your phone as you normally would.
However, based on feedback, some travelers have encountered faulty SIM cards that don’t work correctly, with one reviewer specifically mentioning, “Faulty sim card. The solution they give me is to call a phone I can’t call because I don’t have coverage.” This highlights a key issue—if your SIM fails or doesn’t activate, customer support might be slow and unhelpful, leaving you without internet in an unfamiliar country.
The non-refundable policy is worth noting, especially if you’re unsure about the quality. You only get one shot at this SIM card, so it’s essential to be confident in your choice before picking it up.
Detailed Breakdown of the Experience

Pickup & Location
The pickup process is designed for convenience, with counters located inside the main terminal buildings. Terminal 1’s counter operates from 06:30 to 21:00, while Terminal 2’s runs until 23:00. This gives you ample time to grab your SIM after your flight lands, even if you’re arriving late at night.
Cost & Value
At $37.37 per person, this SIM card seems like a decent deal for a 15 to 30-day stay. Unlimited 5G data is rare at this price point, and the fact that you don’t need to return the SIM makes it even more attractive. For travelers planning to spend extended periods in Japan, especially those relying heavily on internet, this could be a cost-effective solution.

Who Should Consider This SIM Card?

This SIM card is ideal for budget-conscious travelers planning to stay in Japan for at least a couple of weeks. If you value simplicity and convenience, and are okay with the potential risk of faulty units, it might be a good choice.
However, if you rely heavily on uninterrupted connectivity, especially for work or critical communication, you might want to consider alternative options, such as more reliable local providers or rental solutions with better customer support.
Final Thoughts: Is It Worth It?

This Unlimited 5G SIM card at Narita Airport offers a compelling package—easy pickup, unlimited data, and quick installation—at a reasonable price point. It’s a practical choice for those traveling long-term who want to avoid extra device rentals or complicated setups.

If you’re comfortable with the risk and prefer a straightforward solution, this SIM could serve you well, especially if you prioritize value over absolute reliability.
