This is a fairly common issue, especially if the eSIM configuration or carrier settings don’t fully support device-to-device transfers. Let’s walk through a few steps to help resolve the issue.
1. Verify Carrier Support for eSIM Transfers
Start by confirming that your carrier allows eSIM transfers between devices. Not all carriers support this directly, and they might require a new eSIM activation on the new phone. Check your carrier’s website or contact their support for guidance.

2. Restart Both Devices
Before taking further steps, restart both your iPhone 13 Pro and iPhone 16. Sometimes a simple reboot can refresh the network settings and resolve minor transfer issues.
3. Try Transferring Using a QR Code or Carrier App
If your carrier supports it, try using a QR code or the carrier’s app to set up the eSIM on your iPhone 16. Go to Settings > Cellular > Add Cellular Plan on the new iPhone and follow the on-screen instructions to scan a QR code or use the app for activation.
4. Update Carrier Settings
Ensure that both phones are running the latest iOS and carrier settings. Sometimes, outdated carrier settings can block the eSIM transfer. You can check for updates by going to Settings > General > About on your iPhone 16. If an update is available, you'll be prompted to install it.
5. Contact Your Carrier for Assistance
If the steps above don’t work, it’s best to reach out to your carrier. They can issue a new eSIM or help with the transfer process to make sure it works with your new iPhone 16.
