Yes, the Rakuten Big-S fully embraces modern connectivity with robust eSIM support, allowing you to instantly activate cellular plans without a physical card. This future-forward Rakuten device offers the convenience of digital SIMs, simplifying international travel and managing multiple lines with ease.

The Rakuten Big-S proudly features Yes eSIM support, integrating this advanced technology seamlessly into its design. This allows users to enjoy the benefits of a digital SIM card, eliminating the need for a physical nano-SIM. Furthermore, the Rakuten Big-S leverages its eSIM capabilities to offer a robust dual SIM experience. This means you can effortlessly manage two distinct mobile numbers or plans simultaneously on one device – for instance, a personal line and a work line, or a domestic plan alongside an international travel plan. This flexibility drastically simplifies mobile connectivity for modern usage.

Setting up an eSIM on your Rakuten Big-S is a straightforward process. Before you begin, ensure you have an eSIM activation code or QR code provided by your mobile carrier.

  • Navigate to Settings on your device.
  • Tap on Network & internet (or similar, depending on your Android version).
  • Select SIMs.
  • Here, you should see an option to Add eSIM or Download a SIM.
  • You will then be prompted to scan your carrier-provided QR code or manually enter the activation details.
  • Follow the on-screen instructions to complete the activation. Once activated, your new eSIM profile will appear alongside any existing physical SIM or other eSIMs, ready for use.

The integration of eSIM into the Rakuten Big-S provides significant advantages, especially for frequent travelers or those who manage multiple phone numbers. For travelers, an eSIM means no more fumbling with tiny physical SIM cards when crossing borders. You can easily purchase local data plans from supported carriers in your destination country and activate them instantly, often before you even land. This not only offers competitive local rates but also saves you the hassle and risk of losing your primary SIM. Beyond travel, the dual SIM functionality supports better work-life balance, allowing you to separate communications without carrying two devices. As of 2025, the Rakuten Big-S stands as a testament to convenient and flexible mobile connectivity.
