FAQ

Q: Can you place an order first?
A: Can. After receiving the QR Code, you can check it first, but do not use it before arriving at the place.

Q: Is it installed on the original SIM of the warehouse?
A: No. If you originally used eSIM, please switch back to the original Taiwan plan through the "Definition > Line Service > Line Service", and then use Voya after shipping.

Q: Is the QR Code lost or not?
A: Remove the existing eSIM scheme first, and then re-trace it. If it is still lost, you can set "Set > General > Move or Reset iPhone > Reset".

Q: Is the security label "in use" used?
A: If the code is used in the security operation of Voya, the method may be used. It is enough to cut the code to Voya.

Q: Do you want to show E or 3G?
A: It ' s a normal image, because the package cannot be received outside Taiwan. The package shows 4G when it is shipped out.

Q: Is it still under the law outside the International Law?
A: The warehouse has completed all the security steps. In the "line service", it will be completed in a while. For example, if you plan for a large scale in China, you will need to complete the "China International Communication".
