Why an eSIM says the code is already used

Understand the already-used eSIM message and what to do before deleting anything.

Problem
Problem

Your phone says the activation code has already been used, or the eSIM cannot be installed again after deletion.

Quick answer
Quick answer

Most eSIM QR codes are single-use. If the profile was already installed, keep it on that device and contact support before deleting or trying to move it.

Covered in this guide

  • Check whether the eSIM profile is already installed in SIM settings.
  • If it is installed, turn the line on and complete the activation checks instead of scanning the QR code again.
  • If you deleted the eSIM, do not assume the same QR code can reinstall it.
  • Do not try the code across multiple phones unless the plan explicitly supports transfer.
