• Hotspot sharing will occupy bandwidth, and internet speed will vary depending on the terminal device and geographic location. Therefore, the minimum internet speed is not guaranteed. Please confirm before placing an order.
• Some eSIM plans support hotspot sharing, but it is not guaranteed that every phone can successfully share. It is recommended that each person use one eSIM.
• To maintain network quality, unlimited data users must still comply with the fair use policy.
• Abnormal data users may be restricted (daily usage of 5GB may trigger this rule), which could result in internet access being blocked or reduced speed.

  • Large file transfers (upload/download)

  • Streaming live broadcasts
  • Playing mobile games
  • Using social media apps that primarily consist of videos and photos
  • It is also recommended to turn off automatic updates and backup functions, social media auto-play functions, and satellite map navigation mode (use general navigation mode) and cloud drive file transfer functions.

Q1.

Is there an expiration date for the eSIM? How long do I have to activate it after ordering?

You will receive the activation email within 24 hours after placing your order. Please add and activate the eSIM plan within 30 days of placing the order. If the plan is not used within 30 days, it will automatically expire.

If you do not receive the eSIM plan email within 24 hours or have any questions, please feel free to join our official LINE customer service (@381wzxtx), click on the chat bubble at the bottom right corner of the webpage to send a message, or submit your inquiry through the Contact Us page.

Q2.

Should I activate the eSIM before leaving the country or upon arrival?

You can add the eSIM plan to your mobile services in a "non-destination" location and turn it off (Settings - Mobile Services - eSIM plan options).
If you add or activate the eSIM plan in the "destination" location, the time will start counting immediately.

※ For customers purchasing the "Japan eSIM Unlimited Data (FUP / No Throttling) 4G", please activate the plan upon arrival at your destination. Do not activate the plan in advance to avoid early activation. (Scanning or manually activating the plan will immediately activate it and start the time count.)

Q3.

How much is 1GB of data?

1GB of data breaks down to around:
- About 1 hour of using TikTok
- 4 hours of streaming on Netflix1
- 7 hours of listening to music on Spotify
- Up to 500 hours of using Google Maps

Q4.

What's the differences between 4G, 5G?

4G and 5G differ mainly in speed and latency. 4G is great for everyday tasks like browsing, streaming HD videos, and video calls. 5G enhances personal daily life with faster downloads, seamless 4K streaming, instant cloud gaming, and improved AR/VR experiences.
