About this app

Going to Japan? Simnova puts a Japan eSIM on your phone before you fly, so you land with mobile data instead of queueing for a SIM card or pocket WiFi at the airport. Prepaid Japan eSIM plans start at US$1.49 for 1GB over 7 days and connect to NTT docomo, KDDI/au, SoftBank and Rakuten Mobile, with 5G where available.

The same app also has eSIM plans for Indonesia, Thailand, Australia, the United Kingdom and 200+ destinations.

JAPAN eSIM FOR TOKYO, OSAKA, KYOTO AND BEYOND

Install your Japan eSIM at home, then switch it on when you land at Narita, Haneda or Kansai. Coverage is strong in the cities and along the Shinkansen corridors. Expect some gaps in mountain areas and rural Hokkaido and Tohoku.

Why choose an eSIM over pocket WiFi in Japan? There is no rental counter, no deposit, no extra device to charge and nothing to post back before you fly home.

JAPAN eSIM PLANS

- 1GB for 7 days: a stopover or short stay
- 5GB for 30 days: a 7 to 10 day holiday
- 10GB for 30 days: 2 to 3 weeks, or sharing with a laptop
- Up to 50GB, with validity up to 180 days

WHAT IS AN eSIM?

An eSIM is a digital SIM built into your phone. There is no plastic card to swap or lose. Buy a data plan in the app, install it in about 2 minutes, and switch it on when you land.

HOW IT WORKS

1. Check your phone is compatible in the app
2. Pick your destination and data plan
3. Pay securely in the app
4. Install your eSIM at home over Wi-Fi
5. Switch it on when you land

Your plan only starts when your phone connects to a network at your destination. You have 180 days from purchase to install it.

KEEP YOUR NUMBER

Simnova eSIMs are data-only and sit alongside your regular SIM. Calls, texts and banking 2FA codes keep arriving on your usual number, while WhatsApp, Google Maps and your other apps run on Simnova data.

Set Mobile Data and Data Roaming to your Simnova eSIM only, so your home carrier cannot add a roaming charge. The app walks you through it.

WHAT YOU GET

- Instant delivery, usually within seconds
- Hotspot and tethering on every plan
- Data balance in the app at any time
- Top-ups in two taps
- Prepaid, with no contract and no surprise bill
- Nova credit on every purchase, to use on your next eSIM

COMPATIBLE PHONES

Your phone must support eSIM and be carrier-unlocked. Google Pixel 3 and newer and Samsung Galaxy S20 and newer generally qualify, along with many recent models from other brands. Many budget Android phones do not support eSIM, so the app checks yours before you buy.

QUICK ANSWERS

Which network will my Japan eSIM use?
NTT docomo, KDDI/au, SoftBank or Rakuten Mobile.

Does a Japan eSIM include a phone number?
No. It is data-only, so use LINE or WhatsApp for calls and messages.

When should I install my eSIM?
Before you fly, while you are on Wi-Fi at home.

Can I get a refund?
Yes, within 7 days of purchase, if the eSIM has not been installed or activated.
