Using Dual eSIM on US iPhones (iPhone 14 and newer)
US iPhone 14 and newer models support Dual eSIM — two eSIM profiles active simultaneously with no physical SIM card. If your primary plan is also an eSIM (e.g., AT&T, Verizon, T-Mobile eSIM), you can add a Flysimio travel eSIM alongside it. Set your home eSIM for calls and texts, the travel eSIM for cellular data. Both remain active at the same time.
eSIM not working on iPhone?
- Check carrier lock: carrier-locked iPhones may block third-party eSIM profiles. Contact your carrier to unlock.
- Check iOS version: update to the latest iOS before adding an eSIM.
- Make sure you're on Wi-Fi during installation — cellular data is not used for the initial download.
- Restart your iPhone after installation if the eSIM shows "No Service".
- Confirm you've set the travel eSIM as the Cellular Data line in Settings → Cellular.
