How we picked

We sampled prices for the same 5GB / 7-day plan across 5 brands (LAN, Airalo, Holafly, Nomad, Ubigi) on 2026-04, all from US-region store fronts. We don't accept paid placement — rankings are based purely on price-per-GB, network coverage in Japan (KDDI / Docomo / SoftBank), and trip-fit. We disclose where competitors win.

Frequently Asked Questions

Is the cheapest eSIM the best choice for Japan?

For most travelers — yes. Japan's 4G/5G is fast and reliable nationwide on every major carrier; eSIM resellers source from these same networks. The price gap reflects brand and operating model, not network quality. Pick on price unless you stream Netflix daily (then unlimited makes sense).

Will the eSIM work on the Shinkansen and at airports (Narita, Haneda, KIX)?

Yes. KDDI maintains coverage along all Shinkansen routes and at Narita / Haneda / KIX airports. Brief signal loss in deep tunnels (a few minutes) but excellent overall.

Can I use Suica, IC cards, and PayPay with the eSIM?

Apple Pay-linked Suica works perfectly with travel eSIM data. PayPay and Japan-only payment apps require a Japanese phone number for some features — a travel eSIM gives you data, not a Japanese number. Use foreign-card-linked apps instead.

How much data should I get for a 7-day Japan trip?

Casual tourist (Maps + photos + WhatsApp): 3–5 GB. Heavy IG/TikTok user: 7–10 GB. Hotspot for laptop work: unlimited or 15+ GB. Use our data calculator if unsure.

FAQ

Frequently Asked Questions

What is an eSIM?

An eSIM (embedded SIM) is a digital SIM built into modern smartphones. It lets you activate a mobile data plan by scanning a QR code — no physical SIM card needed.

Which devices support eSIM?

iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later, and most recent flagship phones. Check Settings > Cellular > Add eSIM on your device.

Can I make phone calls with the eSIM?

Our eSIM plans provide data only. You can use VoIP apps like WhatsApp, FaceTime, or Skype for voice and video calls over your data connection.

How do I activate the eSIM at my destination?

The eSIM activates automatically when you arrive and enable data roaming in your device settings. Simply install the eSIM before your trip by scanning the QR code, then turn on data roaming when you land.

Can multiple people share one eSIM?

No, each eSIM can only be installed on one device. Please purchase separate plans for each traveler in your group.

What happens when my data runs out?

Your eSIM will stop providing data. You can purchase a new plan on our website and install it on your device to continue using mobile data.

How long is the eSIM valid?

The eSIM must be installed within 6 months of purchase. Once you connect to a network at your destination, the plan duration (e.g. 7 days, 30 days) begins counting down.

What is the refund policy?

Simple rule: if you haven't used it, you can refund it. Not activated → 45-day full refund, any reason. Activated with quality issue → 30-day full refund or free replacement (just describe symptoms, we check logs to resolve). Only non-refundable case: activated and working as described. In case of dispute, PayPal Buyer Protection decides independently (both sides submit evidence). Email [email protected] — response within 24 hours.

What is the difference between eSIM and a physical SIM card?

An eSIM is a digital SIM embedded in your phone — no physical card to swap. You activate it by scanning a QR code. It works as a second line alongside your existing SIM, so you keep your phone number while using local data abroad. Check device compatibility to see if your phone supports eSIM.

How do I set up eSIM on my iPhone?

On iPhone: Settings > Cellular > Add eSIM > Use QR Code. Point your camera at the QR code we sent to your email. Tap "Add Cellular Plan" and follow the prompts. Before your trip, just enable Data Roaming. See how it works for a step-by-step guide.

Can I install the eSIM before my trip?

Yes, and we highly recommend it! Install the eSIM while you have WiFi. The data plan timer only starts when you connect to a network at your destination — not when you install. Browse our available plans and set up before you fly.

Do I need to remove my physical SIM card?

No! Your eSIM works alongside your physical SIM (dual SIM). Keep your regular SIM for calls and texts, and use the eSIM for affordable mobile data abroad. Check compatible devices that support dual SIM.
