FAQ

Should I install the eSIM before I travel?

Yes. Install it before departure while you have reliable Wi-Fi, then activate mobile data after arrival.

Can I scan the same QR code twice?

Usually no. Many eSIM QR codes are single-use, so install it on the correct device.

If your iPhone was purchased in mainland China, confirm that the exact model supports eSIM before following these steps. The China-model iPhone eSIM guide explains the current iPhone 17e and iPhone Air rules.
