How often do we take it for granted that our smartphones are always connected?

Yet the moment you head into the mountains or enjoy a camping trip away from the city, your phone suddenly shows “No Service” — a feeling of anxiety that most of us have experienced at some point.

That “common sense” about smartphones is about to change in a major way. Have you heard of Rakuten Mobile’s “Ultimate Satellite Service”? Rather than relying solely on ground-based cell towers, it’s a bold challenge to deliver signals directly from space to your smartphone — a pioneering step into the future of communications.

▮Could “No Service” Become a Thing of the Past? How Space and Smartphones Connect Directly

Until now, smartphones could only receive signals from ground-based antennas (cell towers). As a result, there were inevitably areas — deep in the mountains, on remote islands, or out on the open sea — where towers simply couldn’t be installed and coverage couldn’t reach.

But once the “Ultimate Satellite Service” becomes a reality, anywhere you can see the sky, you’ll be able to receive signals directly from satellites orbiting in space.

In other words, even in places where ground-based antennas can’t reach, as long as you have a view of the sky, your smartphone will work. This isn’t just an improvement in connectivity — it has the potential to transform our very way of life.

▮Commercial Launch Across Japan in 2026

The most reassuring aspect of this technology is that it’s not a pipe dream — it’s moving forward as a concrete plan. Rakuten Mobile is targeting a nationwide commercial launch in Japan in Q4 2026 (October–December).

A future where you can connect anywhere the sky is visible is just around the corner. When this service launches, Rakuten Mobile users will be among the first to experience its benefits.

▮How Will Our Lives Change?

What kind of changes will this technology bring to our daily lives once it’s fully up and running?

1. Peace of Mind with “Connect Anywhere”
Whether camping, hiking, or during a disaster when ground-based towers are unavailable, satellite signals from above become a vital communications lifeline. The ability to reach loved ones no matter where you are is, for people today, the greatest source of reassurance imaginable.

2. Even More Room for Adventure
You’ll be able to head out with confidence to places you previously gave up on because of poor signal. With maps, social media, and emergency contact options always available, the possibilities for travel and outdoor activities become truly limitless.

3. Experience Japan’s Cutting-Edge Technology
The ability for a smartphone to communicate directly with satellites is still a rare, revolutionary achievement worldwide. Choosing Rakuten Mobile means becoming a “pioneer” — experiencing tomorrow’s communications environment before anyone else.

▮The Strongest Plan for “Now” and the Satellite Service for “Tomorrow”

Satellite communications may be the technology of tomorrow, but Rakuten Mobile’s “Strongest Plan” already packs powerful specs to support your life today.

Unlimited data, free calls via Rakuten Link, and a full lineup of features to make everyday life as comfortable as possible. Enjoy a more convenient life today, while looking forward to “connecting with space” in 2026. Isn’t that the smart smartphone user’s choice?

Rakuten Mobile is more than just a carrier. It’s a company that keeps pushing into new frontiers — including outer space — with the mission of making smartphones accessible to everyone, no matter where in Japan they are.
