## What is Mobile Companion?

Companion Mobile is the app that makes staying connected during your trip to Japan effortless.

Buy a data eSIM in seconds, install it before you even leave home, and stay connected from the moment you land — no queuing at a store, no physical SIM card to swap.

WHY COMPANION MOBILE

- Data plans built for Japan (7 or 30 days), on a reliable local network
- Instant installation by QR code or direct link, before or after you arrive
- Your regular number stays active for calls and texts: the eSIM only handles your internet data
- Top up directly from the app if you run out of data during your trip
- Track your usage and plan validity at a glance
- Home screen widget to check your remaining data without opening the app
- Secure payment by card, Apple Pay, or Google Pay
- Quick sign-in with email, Google, or Apple
- Built-in FAQ and live chat support whenever you need help

A JAPANESE IP ADDRESS, REAL BENEFITS

With a Companion Mobile eSIM, you browse with a native Japanese IP address: unrestricted access to local services (restaurant bookings, train tickets, Japanese streaming, and more).

SIMPLE FROM START TO FINISH

1. Choose your Japan plan (duration and data amount)
2. Pay securely
3. Install your eSIM by QR code, even before you leave
4. Manage, track, and top up your plan throughout your trip

Companion Mobile is built for travelers who want reliable connectivity in Japan, without the hassle or surprises.

## Version history (last 4 releases)

### 1.0.4 — 2026-09-28

Track your plan

Usage alerts: the app lets you know when you have used half of your data, then when you are running low, even when it is closed. If your plan is used up and a top-up is available, it offers you one.
Data allowance and usage shown exactly as reported by the operator.
Validity shown in days, in English and French. An unreliable countdown is no longer shown.
Network shown as "4G/5G", included country shown with its flag and name.
eSIM statuses translated (ready to install, in use, expired…) with icons.
Top-ups

After a top-up, your new allowance appears straight away, marked "being activated", until the operator confirms it.
A second notification tells you when the top-up is active.
A failed or unconfirmed payment is never shown as successful.
Your eSIMs

Expired eSIMs can be removed from your list.
Cancellation is only offered for an eSIM that can really be cancelled, never for a top-up.
Account and help

Edit your name from your profile.
Show or hide your password while typing.
Referral code checked before you pay.
Support: message us directly on WhatsApp from the app.

More reliable plan catalogue, even on a poor connection, with plans sorted from smallest to largest.
