Q1：Do I need to issue the QR Code immediately after receiving the Activation URL?
A: ❌ No, you do not need to issue it immediately.
🕒 Newly applied eSIMs have a 45-day QR Code issuance period.
Recommendation:
✅ Issue the QR Code before departure.
✅ This prevents the usage period from starting early due to flight changes, typhoons, or trip cancellations.
Q2：What does “Complete operation within 44 days, automatically activated on the 45th day” mean?
A:
This means:
📌 The Activation URL operation period before pressing “Issue”.
⏰ Please complete QR Code issuance within 45 days after receiving the Activation URL.
⚠️ If the QR Code is not issued after 45 days:
➡️ The system will automatically start counting the usage period.
➡️ The countdown will begin even if you are outside Japan.
Q3：Will the usage period start immediately after pressing “Issue”?
A: ❌ No.

The following steps must be completed:

2️⃣ eSIM installation
3️⃣ Arrival in Japan
4️⃣ Smartphone connects to the docomo network
➡️ The eSIM will then be officially activated and the usage period will begin.
Q4：How is the usage period calculated?
A:
After eSIM activation:
🇯🇵 The usage period is calculated based on Japan Standard Time (JST) calendar days.
Example:
📅 7/14: Issue and install eSIM in Taiwan
📅 7/15: Arrive in Japan and connect to the docomo network, will be counted as Day 1.
Q5：Can I issue the QR Code during system maintenance?

✅ Please complete QR Code issuance before Tuesday 22:00.
⚠️ If you operate during maintenance:
・The status may remain pending.
