Purchase Notice
- This product provides data-only service and does not include a local phone number or voice call service.
- Hotspot sharing is supported, but continuous use may affect internet speed and experience. It is recommended that each device uses its own eSIM. For multiple users sharing a hotspot or extended high-definition streaming, consider a “total data plan” for more flexible data allocation.
- Coverage may vary by country, as telecom tower distribution is affected by terrain, buildings, and crowded areas, which can cause temporary signal fluctuations. Your phone will automatically switch to the best frequency band depending on the environment; if 5G signals are weak, it will downgrade to 4G/LTE to maintain stable connectivity. For abnormal network speeds, try moving to a different location, toggling airplane mode to reconnect, or contacting online customer service for assistance.

Reminders
Connectivity is unavailable while the cruise is sailing on international waters. Once the ship docks, enable “Data Roaming” on your phone and wait 1–3 minutes—the system will automatically search for and connect to local networks in Japan or Korea.

Some apps (e.g., mobile payments, online banking, streaming services, short-video apps, or AI applications) may impose regional IP or security restrictions. These limitations are app-side mechanisms and are not network connectivity issues. It is recommended to check your frequently used apps’ roaming support before travel to ensure smooth usage.
During roaming, internet speed may fluctuate due to location, terrain, building obstructions, number of users, or weather conditions. This is normal. If you experience slow speeds, try moving to a different location, toggling airplane mode to reconnect, or contact online customer service for assistance.
Hotspot tethering is supported; however, continuous sharing may impact your connection quality and speed. For the best experience, we recommend a dedicated eSIM for each device. Additionally, if you plan to watch long videos or perform heavy downloads/uploads in a short period, we suggest using data moderately or choosing our "Total Data Plan" to ensure a smooth and stable connection.
