Does the Rakuten Big Support eSIM?

Yes, the Rakuten Big supports dual SIM functionality. It combines one physical nano-SIM slot with its integrated eSIM for flexible network usage. This allows you to manage two different phone numbers or network plans simultaneously on one device.

Activating an eSIM on your Rakuten Big is a straightforward process. You typically need to:

• Go to your phone's 'Settings' menu.
• Navigate to 'Network & Internet' or 'Connections'.
• Look for 'SIM card manager' or 'Add mobile plan' and follow the on-screen prompts, often involving scanning a QR code provided by your carrier.

Utilizing an eSIM on your Rakuten Big in 2025 offers several advantages. It simplifies switching carriers and managing international travel, as you can easily activate local plans digitally. Furthermore, it frees up the physical SIM card slot for another carrier or if you prefer to retain a physical SIM for backup.
