Frequently Asked Questions

What is a Japan eSIM and how does it work?

A Japan eSIM is a digital SIM card built into your phone that lets you activate a Japanese mobile data plan without inserting a physical chip. You buy a plan online, scan a QR code, and connect immediately to local cellular networks like NTT Docomo or KDDI upon landing in Japan.

Which mobile networks does Get Japan eSIM use?

Get Japan eSIM connects to Japan's major telecommunication networks: NTT Docomo and KDDI (au). Your device will automatically switch to whichever carrier has the strongest 5G or 4G LTE signal in your location.

When should I install my Japan eSIM?

You should install your eSIM QR code prior to departing on your trip while connected to a stable Wi-Fi network. Your data plan validity period will typically begin only when the eSIM connects to a supported Japanese network after arrival.

Can I use mobile hotspot and data tethering with a Japan eSIM?

Yes, mobile hotspot and data tethering are fully supported on Get Japan eSIM plans, allowing you to share your high-speed connection with laptops, tablets, or other smartphones.

Will my phone work with a Japan eSIM?

An eSIM works with any carrier-unlocked smartphone that supports eSIM technology. Compatible devices include iPhone XS and newer models, Samsung Galaxy S20 series and newer, and Google Pixel 3 and newer.

Can I keep my WhatsApp number and primary SIM active while using the eSIM?

Yes. You can keep your primary physical SIM card enabled in your phone settings for SMS and voice calls while setting your Japan eSIM as your dedicated line for mobile data. Your WhatsApp account and number will remain completely unchanged.

How much mobile data do I need for a trip to Japan?

For standard navigation, translation apps, web browsing, and social media, 1GB to 2GB per day (or a 10GB–20GB package for two weeks) is sufficient for most travelers. For heavy video streaming or hotspot usage, choose an unlimited data plan.

Does Get Japan eSIM work on the Shinkansen (Bullet Train)?

Yes, the NTT Docomo and KDDI networks used by Get Japan eSIM provide extensive mobile coverage along the Shinkansen routes between major cities, as well as inside underground station corridors.

How do I receive my Japan eSIM after purchasing on Savylo?

Upon completing your purchase on Savylo, your eSIM installation QR code, confirmation details, and step-by-step setup guide are instantly sent to your email address.

What is the difference between an eSIM and a pocket Wi-Fi rental in Japan?

An eSIM requires no hardware pick-up, charging cables, or return shipping, operating entirely inside your smartphone. Pocket Wi-Fi requires carrying an extra battery device and returning it at the airport before departure.
