Unlimited Data 5G SIM for Japan, Newchitose Airport: A Practical Guide for Travelers

When arriving at Newchitose Airport in Chitose, Japan, you’ll find a handy way to stay connected without breaking the bank — the Unlimited Data 5G SIM card offered by Telecom Square. At just $16.29 per person for anywhere from 4 to 10 days, this SIM promises blazing-fast internet speeds and wide coverage across Japan — from bustling Tokyo and Osaka to the quiet countryside of Hokkaido. It’s a straightforward solution for travelers who rely on their phones for navigation, translation, and sharing their adventures.
What we really appreciate about this SIM is its unlimited data — no worries about hitting a cap or throttling speeds, so you can stream videos, use maps, and stay connected on social media without interruption. Plus, the ease of pickup directly at the airport makes it a convenient option for travelers who want to get online immediately upon arrival.
However, a key point to keep in mind is that this SIM is exclusively for your mobile phone, not a WiFi router.

An In-Depth Look at the Unlimited Data 5G SIM Experience

Traveling in Japan offers a wonderful mix of vibrant cities, serene countryside, and unique cultural sights. Staying connected is increasingly vital, whether it’s for navigation, translation, or sharing your experiences on social media. The Unlimited Data 5G SIM card from Telecom Square is designed to make this straightforward and affordable, especially for travelers arriving at Newchitose Airport in Chitose.
What’s Included and What’s Not
For $16.29, you receive a SIM card tailored for your mobile phone and a simple instruction manual. There’s no included SIM pin, meaning you’ll need to have one available from your phone or device. The package doesn’t include voice calls or texts, so if those are essentials, you might want to prepare for that separately.
This SIM is exclusively for data, which is a perfect fit for most travelers who rely on apps, maps, and social media rather than traditional calling. It’s a hassle-free way to stay online, with the added comfort of nationwide coverage that spans urban centers and rural areas, thanks to an extensive network.
Ease of Pickup at New Chitose Airport
Most travelers will appreciate the convenience of picking up their SIM at the airport. The meeting point is clearly specified at Bibi, Chitose, making it easy to grab your SIM as soon as you land. Just remember to do so during business hours — otherwise, pickup might be invalid, and no refund is available if you miss it.
Speed and Reliability
The standout feature here is speed. With blazing 5G speeds, you can stream videos without buffering, download maps in seconds, and keep social media updates flowing. Several reviews highlight the reliability of the network, which is crucial in a country where mobile connectivity is generally strong and widespread.
Who Will Benefit Most?
This SIM caters well to independent travelers, backpackers, and digital nomads heading for a week or two in Japan. It’s perfect if you plan to move around extensively — from the airports to city streets and rural areas — and need uninterrupted access. It also suits those who prefer not to fuss with WiFi hotspots or expensive roaming plans.
Possible Drawbacks
The main limitation is that the SIM does not include voice or text services. If you want to make local calls, you’ll need to arrange that separately or use internet-based calling apps like WhatsApp or LINE. Also, it’s for a single device only — no sharing with multiple gadgets unless you have a compatible device or a separate hotspot solution.
Practical Usage and Tips
- Remember to activate the SIM right after pickup for the best experience.
- Keep an eye on the fair usage policy — though the data is unlimited, there might be some restrictions if you use excessive bandwidth.
- If your trip exceeds 10 days, check if extending or multiple SIMs are available.
- Be aware that picking up the SIM during business hours is essential to avoid inconvenience.
