✨ Does Unlimited Data Enhance Security?
The Pitfalls of Public Wi-Fi and Rakuten Mobile’s Solution

First, let’s look at why “unlimited data” is closely related to security, along with the dangers of public Wi-Fi.

✅ Dangers of Public Wi-Fi: Your Information Might Be Exposed?

Free and easy-to-use public Wi-Fi is appealing, but it actually carries many risks:

• Risk of information leakage: On unencrypted Wi-Fi, data being sent and received (IDs, passwords, credit card information, etc.) can be intercepted.
• Fake Wi-Fi (impersonation access points): Malicious third parties set up fake Wi-Fi hotspots that look exactly like legitimate ones, stealing information from connected users.
• Malware infection: The risk of malicious software being sent via public Wi-Fi is not zero.

These risks pose a significant threat, especially when used for business or when handling sensitive personal information.

✅ Why Rakuten Mobile’s Unlimited Data Tethering Becomes Your “Strongest Shield”

This is where Rakuten Mobile’s unlimited data tethering comes in handy:

• Your own secure Wi-Fi hotspot: Your smartphone becomes your personal Wi-Fi router. Since it’s not shared with an unspecified number of people like public Wi-Fi, the risk of information leakage is greatly reduced.
• Encrypted secure communication: Tethering connections are protected by strong encryption like WPA2/WPA3.
• Peace of mind with unlimited data: You can always use your phone’s tethering without worrying about data limits, eliminating the need to connect to dangerous public Wi-Fi.

💡Tip: With Rakuten Mobile’s “Rakuten Saikyo Plan,” the fee varies depending on data usage, but it will never exceed 3,278 yen (3,580 yen including tax) per month, no matter how much you use. Tethering is also available at no additional charge.

🛡️ Specific Measures for Rakuten Mobile Users to Further Enhance Security

In addition to the peace of mind from unlimited data, here are measures to further strengthen your security:

1. Strong Password Setting and Thorough Two-Factor Authentication

• Set complex passwords for all online services, including Rakuten Mobile account information, and change them regularly.
• Enable two-factor authentication (2FA) wherever possible to reduce the risk of unauthorized access.

2. Smartphone Device Security Measures

• Keep OS and apps up to date: Always update to the latest OS and keep apps updated to fix known vulnerabilities.
• Install security apps: Install antivirus apps to constantly monitor and protect your smartphone.
• Utilize biometric authentication: Set up fingerprint or facial recognition to prevent unauthorized unlocking.

3. Regular Data Backup Habits

• In case of loss, damage, or virus infection, regularly back up important data such as photos and contacts.
• Rakuten Mobile users can also utilize the free storage (50GB) of “Rakuten Drive,” available as a Rakuten member benefit, to securely store data in the cloud.

4. Utilizing VPN Services (Further Enhancement)

• While tethering connections are secure, using a VPN (Virtual Private Network) service can further enhance anonymity and security.
• Using a VPN encrypts communication paths, enabling more private communication.
