■ After arriving in a covered destination, please enable "Data Roaming" for the eSIM to access mobile data normally.
■ Troubleshooting
If you are unable to access the internet, please check the following:
1. The eSIM is set as the default mobile data line.
2. Data Roaming is enabled.
3. Turn Airplane Mode on and then off.
4. Manually switch the network operator.
5. Manually configure the APN.
■ Supports Multiple Installations
eSIM can be installed, deleted, and reinstalled up to 10 times on the same device.
Reinstallation is allowed within the validity period of the QR code (for unactivated eSIMs) or the data plan (for activated eSIMs). After expiration, reinstallation is not possible.
■ Network Performance
Actual signal strength, network speed, and 4G/5G service availability may vary depending on your location, the local carrier's network coverage, your device compatibility, as well as environmental factors such as terrain, buildings, and weather conditions.
■ Disable Domestic SIM Card Roaming
Before using an eSIM, make sure to turn off data roaming on your domestic SIM card to avoid incurring high international roaming charges. You will be responsible for any related fees, including roaming charges, overseas SIM card/eSIM purchase costs, and transportation expenses. No additional compensation will be provided.
■ Maintaining Fair Usage Policy
To maintain network quality and the Fair Usage Policy (FUP), telecommunications companies may throttle users who consume large amounts of data within a short period, leading to slower speeds or inability to connect. To ensure stable internet access, please avoid activities that consume excessive data, such as prolonged video streaming/downloading, software updates, or sharing your network (hotspot).
