My phone says the eSIM is already in use

Short answer: the eSIM profile may already be installed or already used. Most eSIMs cannot be installed on multiple devices.

Check first

1. Look for the eSIM in your current phone's SIM/eSIM list.
2. If you recently changed phones, check the old phone too.
3. Do not delete the eSIM unless support tells you to.

Contact 4S support through support@4s.net, a Zendesk support ticket, or Zendesk live chat. Do not reply to hi@4s.net; it is an automatic order and installation email sender.

When contacting support, include your order email, ICCID if available, destination, phone model, and screenshots of the error or SIM/eSIM settings page.
