Local know-how
What to know before you land in Japan
Coverage and networks
Japan runs on three nationwide networks: NTT Docomo, KDDI (au) and SoftBank. Docomo has the deepest rural reach, SoftBank is strong in Tokyo, Osaka and along the Shinkansen, and KDDI sits in between. All three support eSIM travelers; the plan card shows which one your plan uses.
Landing and activation
Install before you fly: Narita and Haneda have usable free Wi-Fi, but JR station Wi-Fi is unreliable for a first-time setup. Switch the eSIM on at the gate and you'll be online before baggage claim.
Which plan fits your trip
Japan is a heavy-data country: maps, translation and QR menus add up fast. For a 7 to 10 day trip, 10 GB is the sweet spot; unlimited pays off if you hotspot a laptop or stream. Staying only in Tokyo? A smaller plan plus ubiquitous convenience-store Wi-Fi works.
Install in three steps
Set up your Japan eSIM in under a minute
- 1
Buy the plan and get your QR code
Pay once with card, Apple Pay, Google Pay or crypto. The activation QR arrives in your dashboard and email within seconds.
- 2
Scan the QR from your phone settings
On iPhone: Settings → Cellular → Add eSIM → Use QR Code. On Android: Settings → Network → SIMs → + → Use QR code. Or open the GetSim app and tap install, no QR scanning needed.

Land, switch it on
Set the GetSim eSIM as your default for cellular data. Your home SIM keeps handling calls and 2FA SMS in the background.
Your real number stays online. The eSIM only handles data. Calls, SMS, banking 2FA all keep arriving on your home SIM.
Crossing borders?
Going to more than just Japan?
A regional bundle covers Japan and 195+ other countries on a single eSIM, often cheaper than buying separate single-country plans for a multi-stop trip.
Frequently asked about Japan eSIMs
Yes. The GetSim eSIM installs as a second profile on your phone. Your home SIM and number stay active for calls and SMS. Set the GetSim eSIM as the default for cellular data only.
Plans run on tier-1 mobile networks in Japan. The exact carrier depends on the plan; you'll see the network name on each plan card before you pay.
Typical activation is 1–3 minutes after switching the eSIM on. Many travelers install the eSIM at home over Wi-Fi and toggle it on the moment the plane lands.
GetSim eSIMs are data-only. For voice and SMS, use apps like WhatsApp, FaceTime, Signal or Telegram. They all work seamlessly over the eSIM data. If you need a real phone number for verifications, pair the eSIM with a GetSim virtual number from the same wallet.
Top up the eSIM directly from your dashboard or the GetSim app, no need to install a new profile. Top-ups are billed per-GB at the same rate as the original plan.
