How long should I wait for eSIM to ship after payment?
Because our system needs to check your order, and it takes a certain amount of time to prepare the QR code.
If you purchase the plan on the day of the destination or the next day, the plan will be sent to your email address within 2 hours after the order is placed.
If you purchase 2 days or more in advance, we will send it to you in advance one day in advance.
Can I have multiple phones scan a same QR code?
Sorry you cannot. When you use your phone to scan the QR code for the first time, the binding has been established, and other phones cannot no longer scan and use the QR code. In addition, One QR code cannot be scanned multiple times, and the scan will not work if the number of scans exceeds the limits.

4G/LTE service is available in most countries. You can check the network support on the details page of each data package.
