A Japan eSIM is a digital SIM card specifically designed for travelers. Powered by UK-based eSIM Go technology, Roam Bear provides native signals from local carriers. The best part? No QR code scanning is required—you can use our "One-Click Install" feature directly through the Roam Bear App to set it up on your iPhone securely and instantly.

It’s as simple as four steps: 1) Purchase your plan in the App. 2) Before your trip, tap "Install eSIM" while connected to stable Wi-Fi (no QR code needed). 3) Upon arrival in Japan, switch to your Roam Bear eSIM and turn on "Data Roaming" to get online. Note: The validity period only starts once you connect to the local network; installing it before your trip won't consume any days. Also, remember to disable data on your primary SIM to avoid unexpected roaming charges.

Roam Bear’s Japan eSIM connects to premium local carriers like NTT Docomo and SoftBank, offering up to 99% coverage across major cities including Tokyo, Osaka, Kyoto, Hokkaido. We ensure high-privacy, low-latency, and high-speed network services for your journey.

Yes! All Roam Bear plans support personal hotspots. You can share your data with your iPad, laptop, or travel companions' phones. Whether you choose a fixed data plan or an unlimited plan, there are no additional restrictions on sharing.

Yes, iPhones support Dual SIM Dual Standby. However, please note: 1) To receive SMS or calls on your original number, you must keep "Voice Roaming" on, which usually incurs high international roaming fees. 2) You MUST turn off "Data Roaming" for your primary SIM to prevent your phone from using it for internet data. We recommend using internet-based calling (like WhatsApp, LINE, or FaceTime) to save costs.

We provide high-speed 4G/5G local native networks. If you choose an unlimited plan, you get 1GB of high-speed data daily, after which speeds are throttled to 1.25Mbps. This reduced speed is still about 10 times faster than the industry standard of 128kbps, making it sufficient for messaging, navigation, social media, and streaming 480P videos.

Please activate the eSIM in the App within 180 days of purchase. The validity period begins the moment you arrive in Japan and successfully connect to the local network. Therefore, you can safely complete the installation 1-2 days before your departure.

Currently, if your data is exhausted, you will need to purchase a new plan and install it. However, Roam Bear is launching an "In-App Top-up" feature soon, allowing you to renew your existing eSIM without downloading a new profile. We recommend estimating your data needs or choosing a larger plan before you depart.

Roam Bear values every user's experience and provides multi-language customer support. If you have questions, contact us via the in-app live chat, email us at customer-service@travelroambear.com, or reach out through our official social media (FB/IG). We strictly protect your privacy—your data and personal information will never be shared with third parties.

Four reasons to choose Roam Bear: 1) Strict Privacy Protection: We take data security seriously and promise never to provide your usage behavior or personal info to third parties. 2) Secure One-Click Installation: Skip the hassle of searching through emails for QR codes and avoid phishing risks; install directly via our App. 3) Premium Local Routes: Powered by eSIM Go (not CMCC/CMHK), we provide native local networks for a stable, high-speed, and low-latency experience. 4) Real-Time Management: Track your data usage and validity anytime in the App, with pricing more competitive than international brands like Saily or Airalo.
