Introduction

Hello to everyone considering switching to Rakuten Mobile! Everyone wants to save on communication costs, right? Especially “call charges” which can become expensive depending on usage. However, if you’re a Rakuten Mobile user, you can solve that problem with a free app called “Rakuten Link”! This time, we’ll thoroughly explain the appeal of Rakuten Link and provide information to help you achieve a “0-Yen Call Bill Life.” To sign up for Rakuten Mobile without knowing about this app is, frankly, a “loss”!

What is Rakuten Link?: The Magic App for Free Calls & SMS

Rakuten Link is a communication app provided by Rakuten Mobile. With this app, you can enjoy the following services without any extra charges:

  1. Completely Free Domestic Calls: Not only between Rakuten Mobile users, but also calls to other carriers’ mobile phones and landlines within Japan are unlimited in time and frequency when made through the Rakuten Link app.
  2. Unlimited Domestic SMS: Domestic SMS (Short Message Service) can also be sent and received for free via the Rakuten Link app.
  3. Free Calls & SMS from Overseas to Japan: Even when you’re abroad, if you have a Wi-Fi connection, you can use the Rakuten Link app to make calls and send SMS to Japan for free. No need to worry about international roaming charges.
  4. Partial Free Data Usage Overseas: In eligible countries/regions, you can use up to 2GB of data per month without additional charges (speed throttled after exceeding 2GB).

The Appeal of a “0-Yen Call Bill Life” Achieved with Rakuten Link

The biggest appeal of Rakuten Link is undoubtedly the “complete elimination of call charges.”

  1. Budget-Friendly Savings: By having a 0-yen call bill every month, you can significantly reduce your overall communication costs. The savings are especially substantial for those who make frequent calls.
  2. No Need for Unlimited Call Plans: There’s no need to subscribe to expensive unlimited call plans offered by other carriers. With Rakuten Link, you can enjoy the benefits of unlimited calls with just the basic monthly fee.
  3. Reduced International Call Costs: When traveling abroad, you won’t have to worry about expensive international call charges when contacting family or friends in Japan.

How to Use is Surprisingly Simple!

Getting started with Rakuten Link is very straightforward.

  1. Sign up for Rakuten Mobile: First, sign up for a Rakuten Mobile SIM card or eSIM and complete the setup on your smartphone.
  2. Download the Rakuten Link App: Download the “Rakuten Link” app from the App Store (iPhone) or Google Play Store (Android).
  3. Initial Setup: Launch the app, log in with your Rakuten ID, and follow the on-screen instructions to complete initial setup, such as phone number verification.
  4. Start Using Immediately!: Once setup is complete, you can simply make calls and send messages through the Rakuten Link app, just like you would with your standard phone app.

Important Notes: Tips for Smart Usage

While Rakuten Link is very convenient, there are a few points to be aware of.

  1. Requires Data Connection: Rakuten Link uses an internet connection, so data usage is required for calls and SMS. In places without Wi-Fi, it will consume your Rakuten Mobile data (gigabytes).
  2. Emergency Calls Not Available: Emergency calls such as 110 (police) and 119 (fire/ambulance), as well as toll-free numbers and some special numbers, cannot be made through the Rakuten Link app. For these numbers, please use your smartphone’s standard phone app.
  3. Call Quality Depends on Internet Environment: Call quality may be unstable or audio may drop out depending on network congestion or signal strength.

Conclusion

Rakuten Link is a powerful service that is a major strength for Rakuten Mobile, and it is very appealing to anyone looking to significantly cut down on communication costs. A “0-Yen Call Bill Life,” free from worries about call and SMS charges, will greatly change your mobile experience.

If you’re considering switching to Rakuten Mobile, understanding the benefits and caveats of Rakuten Link and using it smartly will help you achieve a more comfortable and affordable smartphone life.
