If you've installed an eSIM and want to use it for mobile data (while keeping your regular SIM for calls and texts), you’ll need to tell your iPhone which SIM to use for data.
Here’s how to set your eSIM Copilot plan as the data SIM:
📱 Steps to set your data SIM
- Open Settings
- Tap Mobile Data (or Cellular)
- Tap Mobile Data again (under the SIMs section)
- Choose your eSIM Copilot line
- Done! Your iPhone will now use eSIM Copilot for data
💡 Tip
If you’re travelling, don’t forget to turn on Data Roaming for your eSIM:
- Go to Settings → Mobile Data → [your eSIM Copilot line]
- Toggle Data Roaming to ON
This setup lets you stay connected abroad using eSIM Copilot, while keeping your usual number active for calls and messages.
