Check your plans
- Your iPhone must be unlocked or both mobile data plans must be from the same network provider.
- Both plans must be set up and ready to use.
- Your network provider or network providers must support Dual SIM with eSIM.
- If a CDMA network provides your first SIM, your second SIM won't support CDMA. Contact your network provider for more information.
eSIM on iPhone is not offered in China mainland. In Hong Kong and Macao, only iPhone SE (2nd generation), iPhone SE (3rd generation) and iPhone XS feature eSIM. Find out about fixing issues with Dual SIM when using two nano-SIM cards in China mainland, Hong Kong and Macao.
If you can't set up your eSIM
- Check with your network provider to see if your iPhone plan is eligible for Dual SIM service.
- If you have an enterprise or corporate mobile service plan, check with your company or network provider to see if they support this feature.
- Make sure your network providers support cover in your area and that there are no service outages.
- Make sure your mobile data plans are set up, ready to use and don't have a billing-related blockage.
If you still can't set up your eSIM, contact your network providers for support.
If you can't see one or both mobile data plans
You should see both of your plans when you go to Settings > Mobile Data or Settings > Cellular. Here's what to do if you can't.
If you can't see your eSIM plan
If you can't see your nano-SIM card plan
Make sure your nano-SIM card is seated correctly in the SIM tray:
- Remove the SIM tray and inspect the SIM cards for signs of damage or corrosion.
- Remove your SIM card from the SIM tray, then put the SIM card back.
- Make sure you close the SIM tray completely, so that it isn't loose.
- Open Control Centre and make sure both of your network providers appear in the status bar.
If the nano-SIM card doesn't work, if it doesn't fit or is bent, or if you see "Card is not compatible with LTE" on your iPhone, contact your network provider for a new nano-SIM card.
If you're on a call and see No Service on your other line
Your iPhone can use one mobile data network at a time. When you're using one line to make a call, your other line will show No Service. If your network provider supports Wi-Fi Calling on your other phone number and you have Wi-Fi Calling turned on, you can answer incoming calls on that number. When you're on a call that isn't your default data line, you'll need to turn on Allow Mobile Data Switching.
