Short answer: usually no. Most eSIM profiles can only be installed once.
If you delete the eSIM from your phone, the original QR code or activation code may not work again.
What to do
- Do not keep trying the same QR code repeatedly.
- Contact 4S support through support@4s.net, a Zendesk support ticket, or Zendesk live chat with your order number or ICCID.
- Tell 4S support whether the eSIM was installed, deleted, or moved to another phone.
Do not delete your 4S eSIM until your trip is over and you are sure you no longer need it.
