Câu hỏi thường gặp
Về eSIMs choJapan

  • "A Japan eSIM (embedded SIM) is a digital SIM card that gives you instant mobile data access when traveling in Japan - no physical card, no store visit, no SIM swapping required.

    Unlike a traditional SIM, an eSIM is a small chip built directly into your phone. It stores your carrier’s information digitally, and you can activate it in minutes by simply scanning a QR code.

    With Commbitz Japan eSIM: • Purchase your plan online in seconds • Receive a QR code instantly via email • Scan to install - stay connected the moment you land in Japan"

    Here’s the process:

    1. You purchase a Japan eSIM plan on Commbitz.com
    2. A QR code is sent to your email
    3. You scan the QR code - your phone downloads the carrier profile
    4. The eSIM activates automatically when your phone connects to a network in Japan

    The eSIM standard is developed by GSMA and supported worldwide. It allows your device to switch between carriers without ever touching a physical card. You can even store multiple eSIM profiles and switch between them."

  • "We recommend installing your Japan eSIM before you leave home.

    Why install early: • You need a stable Wi-Fi or data connection to download the eSIM profile • Installing at home means you land in Japan already connected - no airport Wi-Fi hunting • You can troubleshoot any issues from home rather than at the airport

    Does early installation waste data? No - the Japan eSIM data plan only starts counting when you first use data in Japan. Installing the eSIM in advance does not consume your allowance.

    What if I haven’t installed before landing? Most major airports in Japan have free Wi-Fi - you can install immediately after landing. The process takes under 2 minutes."

  • "No - your home SIM card and phone number remain completely active alongside your Commbitz Japan eSIM.

    An eSIM works as a second line on your device (dual SIM). Your setup will be: • Home SIM: active for calls, texts, and as your regular number • Commbitz Japan eSIM: active for mobile data in Japan

    To avoid accidental roaming charges: → Set Japan eSIM as default for ‘Mobile Data’ → Keep your home SIM set to ‘Voice & SMS’ only → Turn off ‘Data Roaming’ on your home SIM in settings

    This way you continue receiving calls on your home number while using fast local eSIM data - with zero roaming charges on your home plan."
