[Phone Compatibility]
1.Your device supports eSIM function
Query Method: Dial "*#06#" in the dial interface. If "EID" is displayed, the phone supports eSIM; if not, it does not support eSIM.
2. The phone is not a network-locked phone
Query Method: Check with your Telecom Operator to see if your device is open for all network bands
* Please check whether you meet the above conditions before purchasing. Only when all conditions are met can you use eSIM normally.
[Set up eSIM]
eSIM can only be installed when there is an internet connection, so it is recommended to install eSIM 6-12 hours before your departure, and Some eSIMs may need to be activated upon arrival at the destination.
[Please DO NOT delete eSIM after installation]
Each QR code can only be installed once, we are not able to assist you if the eSIM has been deleted from your device.
[Disable Domestic SIM Card Roaming]
Before using the eSIM, please ensure that the data roaming function of your domestic SIM card is turned off to avoid incurring high international roaming charges and data conflicts.
[Maintaining the Principle of Fair Internet Usage]
To maintain the quality of internet connectivity and the Fair Usage Policy (FUP), telecom companies worldwide may impose data limits on customers who use large amounts of internet traffic in a short period, which may lead to internet access failure or slower speeds. To ensure you can maintain a stable connection, please try to avoid activities that consume a large amount of data, such as prolonged video streaming/downloading, software updates, sharing the internet (hotspot) with others, or other high-data usage activities.
