How it works

1. 1

   Check your phone supports eSIM

   Most iPhones from the XS onwards and recent Samsung Galaxy, Google Pixel and other Android flagships do. The phone must also be carrier-unlocked.

2. 2

   Add credit and choose a plan

   Sign in to callmins, open eSIM Data, search Japan and pick a plan by data and days. The price comes out of your wallet; nothing renews automatically.

3. 3

   Install it before you fly

   Scan the QR code from another screen, or tap to install on the same phone. It takes about a minute over Wi-Fi. The plan's days only start when it first connects at your destination.

4. 4

   Switch on data roaming when you land

   Set the eSIM as your mobile-data line and turn on data roaming for it. Keep your normal SIM on for calls and texts if you like.

FAQ

How much is an eSIM for Japan?

Plans start at $0.75 and go up with data and days. Every price is shown in US dollars before you buy and is paid from your callmins wallet.

Which network will I use in Japan?

The eSIM connects to established local networks such as Docomo, SoftBank, KDDI (au), choosing the strongest available. Coverage is the same as a local SIM in towns and cities.

Is an eSIM cheaper than roaming in Japan?

For most travellers, yes. Roaming add-ons from home carriers often cost several dollars a day; a prepaid eSIM covers the whole trip for a fixed price with no surprise bill.

Does the eSIM include a phone number?

No. Travel eSIMs are data-only. Use WhatsApp or other apps over data, or add a callmins virtual number to make and receive normal calls and texts over the same data.

When does the plan start?

The validity period starts when the eSIM first connects to a network at your destination, not when you buy or install it. Install it at home over Wi-Fi to be ready on landing.

Can I keep my normal SIM active?

Yes. Phones with eSIM support two lines. Keep your home SIM for calls and texts and choose the travel eSIM for mobile data, with roaming turned off on your home line to avoid charges.

What if I run out of data?

Buy another plan in the app. It installs the same way and you can switch to it in your phone's settings.
