Who Should Consider the “International Call Unlimited” Option?
This option is most beneficial for those who make frequent or long-duration calls to overseas numbers. It is ideal if you:
- Regularly call family or friends abroad.
- Need to contact overseas offices, fixed-line numbers, customer service centers, schools, or government offices—places where app-based calls (like WhatsApp) are often not accepted.
Note: If your communication is limited to app-based calls (e.g., LINE, WhatsApp, Messenger) and you rarely make traditional international calls, this option may not be necessary for you.
The Main Benefit: Peace of Mind
International calling rates vary significantly depending on the destination and call duration, making it difficult to estimate your bill. With the “International Call Unlimited” option (¥980/month), you can enjoy calls to eligible countries and regions without worrying about the meter constantly running. This significantly reduces the psychological burden, especially when you need to make urgent calls for work or personal matters, or if your conversations tend to run long.
Note: There are various ways to make international calls, and the best method depends on who you are calling. The conditions and specific steps for using the “Rakuten Link” app for international calls are detailed in our other guide. Please refer to it for a comprehensive understanding.
