How to install your Vietnam eSIM

Short answer

Install the eSIM over Wi-Fi before you fly. On iPhone open Settings, Cellular, Add eSIM and scan the QR code on your order page. On Android open the SIM manager and choose Add eSIM. A QR code can usually be installed only once, so never delete the eSIM after installing it.

Before you start

  • Check your phone. It must support eSIM and must not be locked to a carrier. Dial *#06#: if an EID number appears, the phone supports eSIM.
  • Connect to Wi-Fi. The phone downloads the eSIM profile from the internet, so it needs a stable connection.
  • Open your order page on a second screen. You scan the QR code with the phone you install the eSIM on, so show the order page on a laptop, a tablet or another phone. If you only have one phone, use manual entry instead.
  • Keep the eSIM once it is installed. A profile can usually be installed only once. An eSIM deleted after installation cannot be restored and is not refunded under our Refund policy.

Other Android phones

Menu names differ between brands. Look in Settings for SIM manager, SIM cards or Mobile network, then choose Add eSIM or Download SIM. If you cannot find it, search the settings for “eSIM”.

If the installation fails

  1. Check the Wi-Fi connection and restart the phone.
  2. Try once more. If the phone says the code is no longer valid, do not keep retrying.
  3. Email [email protected] with the link to your order page, your phone model and a screenshot of the error.

An eSIM that was never installed can be refunded in full: see Refunds and lost QR codes.
