Coral eSIM normally configures the APN automatically after installation, so no manual setup is needed.

Occasionally the automatic settings don't apply and data won't work. In that case, check the APN name shown in your confirmation email or the eSIM details screen in the app, then follow these steps.

On iPhone

  1. Settings → Cellular → select the Coral eSIM line
  2. Open "Cellular Data Network"
  3. Enter the specified APN name under "Cellular Data" (username and password are normally left blank)

On Android

  1. Settings → Network & internet → SIMs → select Coral eSIM
  2. Open "Access Point Names (APN)" and add a new APN with ＋
  3. Enter the specified name and APN, save, then select the new APN

Afterwards, toggle Airplane Mode or restart your phone. See our APN guide for details, or contact support if it still won't connect.
