Having trouble with your smartphone during international travel or returning home?

When traveling abroad, many people face the same challenges regarding mobile connectivity:

• It is a hassle to search for a local SIM card.
• Looking for Wi-Fi spots is time-consuming.
• You are worried about expensive roaming charges after you return home.

With Rakuten Mobile, you can use data in over 100 countries and regions without any special procedures.

How Rakuten Mobile’s “2GB Free Overseas Data” Works

If you are a Rakuten Mobile subscriber, you can use up to 2GB of data per month in designated overseas areas (over 100 countries and regions) at no extra cost.

• No SIM swap or extra apps required: You do not need to replace your SIM card with an overseas-specific one. However, please ensure you configure the settings in the “my Rakuten Mobile” app before departure (explained in the next section).
• Data connection continues even after 2GB: If you exceed 2GB, you can continue using data at a reduced speed of up to 128kbps. If you prefer to maintain high speed, you can add more data for 500 JPY (non-taxable) per 1GB.
• Important note on calls: You can make calls using the “Rakuten Link” app, but rates vary depending on the destination and the country/region. Please be sure to check the official rate table on the website before you travel.

4 Essential Settings to Configure Before You Travel

To ensure a smooth connection abroad, please check these settings before leaving Japan:

1. Turn ON “International Roaming” (in my Rakuten Mobile app)
   Open the “my Rakuten Mobile” app and turn the International Roaming setting to “ON.” If this is not enabled, you will not be able to use data once you arrive. Make sure to complete this before you leave.
2. Turn ON “Data Roaming” (on your smartphone)
   Go to your smartphone’s settings, select “Mobile/Cellular Data,” and turn “Data Roaming” to “ON.” Without this, you cannot connect to overseas networks.
3. Verify and Authenticate the “Rakuten Link” App
   Install the app and complete the login/authentication process while you are still in Japan. Attempting to authenticate after arriving abroad may lead to errors, so it is crucial to do this beforehand.
4. Update your OS
   Keep your smartphone’s operating system (OS) up to date to prevent connectivity issues abroad.

Troubleshooting: What to do if you cannot connect

If you are unable to connect while abroad, please try the following steps:

• Toggle Airplane Mode: Turn Airplane Mode ON, wait a few seconds, and then turn it OFF.
• Restart your device: Power your smartphone OFF and back ON.
• Search for networks manually: Go to your settings and try selecting a network provider manually.
• Re-check International Roaming settings: Verify in the “my Rakuten Mobile” app that International Roaming is set to ON. This is the most common cause of connectivity issues.

Note: During international roaming, you cannot connect to local emergency services (police, fire, etc.) via the Rakuten Link app. In case of an emergency, please use a public phone or consult local facility staff.
