Using Dual SIM with an eSIM

iPhone XS, iPhone XS Max, iPhone XR and later feature Dual SIM with a nano-SIM and an eSIM.1 An eSIM is a digital SIM that allows you to activate a mobile data plan from your network provider without having to use a physical nano-SIM.

Here are just a few of the many ways that you can use Dual SIM:

  • Use one number for business and another number for personal calls.
  • Add a local data plan when you're travelling outside the country or region.
  • Have separate voice and data plans.

With iOS 13, both of your phone numbers can make and receive voice and FaceTime calls and send and receive messages using iMessage, SMS and MMS.2 Your iPhone can use one mobile data network at a time.

1. eSIM on iPhone is not offered in China mainland. In Hong Kong and Macao, only iPhone SE (2nd generation) and iPhone XS feature eSIM. Learn about using Dual SIM with two nano-SIM cards in China mainland, Hong Kong and Macao.
2. This uses Dual SIM Dual Standby (DSDS) technology, which means that both SIMs can make and receive calls.

What you need

To use two different providers, your iPhone must be unlocked. Otherwise, both plans must be from the same provider. If a CDMA network provides your first SIM, your second SIM won't support CDMA. Contact your operator for more information. 

If you have an enterprise or corporate data service plan, check with your company administrator to see if they support this feature.

Set up your mobile data plan with eSIM

On iPhone XS, iPhone XS Max, iPhone XR and later, you can use a physical nano-SIM for a mobile data plan and an eSIM for one or more other mobile data plans. If you don't have a nano-SIM and your provider supports it, an eSIM can serve as your only mobile data plan. The eSIM provided by your network is stored digitally in your iPhone.

To activate your second mobile data plan, you can scan the QR code your provider gave you, use your provider's iPhone app, install an assigned plan, or you can enter the information manually:

Scan a QR code

  1. Open the Camera app and scan your QR code.
  2. When the Mobile Data Plan Detected notification appears, tap it.
  3. Tap Continue, at the bottom of the screen.
  4. Tap Add Mobile Data Plan.

If you're asked to enter a confirmation code to activate the eSIM, enter the number that your network operator provided.

Use a provider's app

  1. Go to the App Store and download your provider's app.
  2. Use the app to purchase a mobile data plan.

Install an assigned mobile data plan

With iOS 13, some providers can assign a mobile data plan for you to install. Contact your provider for more information.

If a plan was assigned to you, follow these steps:

  1. When a notification appears that says Provider Mobile Data Plan Ready to Be Installed, tap it.
  2. In the Settings app, tap Provider Mobile Data Plan Ready to Be Installed.
  3. Tap Continue, at the bottom of the screen.

Enter the information manually

If necessary, you can enter your plan information manually. To enter your plan information manually, follow these steps:

  1. Go to Settings.
  2. Tap either Cellular or Mobile Data.
  3. Tap Add Mobile Data Plan.
  4. Tap Enter Details Manually, at the bottom of your iPhone screen.

You can store more than one eSIM in your iPhone, but you can use only one at a time. To switch eSIMs, tap Settings, tap either Cellular or Mobile Data, and then tap the plan you want to use. Then tap Turn On This Line.

The next sections give you more information about the remaining setup screens on your iPhone.

Label your plans

After your second plan has been activated, label your plans. For example, you can label one plan Business and the other plan Personal.

You'll use these labels when you choose which phone number to use for making or receiving calls and messages, to designate a number for mobile data and to assign a number to your contacts so you know which number you will use.

If you change your mind later, you can change your labels by going to Settings, tapping either Cellular or Mobile Data, and then tapping the number whose label you want to change. Then tap Mobile Data Plan Label and select a new label or enter a custom label.

Set your default number

Choose a number to use when you call or send a message to someone who isn't in your Contacts app. With iOS 13, choose which mobile data plans you want to use for iMessage and FaceTime. With iOS 13, you can choose either or both numbers.

On this screen, choose a number to be your default number, or choose which number will only be used for mobile data. Your other number will be your default. If you want your iPhone to use mobile data from both plans, depending on coverage and availability, turn on Allow Mobile Data Switching.

Use two phone numbers for calls, messages and data

Now that your iPhone has been set up with two phone numbers, here's how to use them. 

Let your iPhone remember which number to use

When you call one of your contacts, you don't need to choose which number to use every time. By default, your iPhone will use the same number that you used the last time you called that contact. If you haven't called that contact, your iPhone will use your default number. If you want to, you can specify which number to use for your calls with a contact. Follow these steps:

  1. Tap the contact.
  2. Tap Preferred Mobile Data Plan.
  3. Tap the number that you want to use for that contact.

Make and receive calls

You can make and receive phone calls with either phone number.

With iOS 13, when you're on a call, if the network provider for your other phone number supports Wi-Fi calling, you can answer incoming calls on your other number. When you're on a call using a line that isn't your designated line for mobile data, you need to turn on Allow Mobile Data Switching to receive calls from your other line. If you ignore the call and you have voicemail set up with your provider, you’ll get a missed-call notification and the call will go to voicemail. Check with your provider for Wi-Fi calling availability, and find out if additional fees or data usage from your data provider will apply.

If you're on a call and your other line shows No Service, either your provider doesn't support Wi-Fi calling or you don't have Wi-Fi calling turned on.1 It could also mean that Allow Mobile Data Switching is not turned on. When you're on a call, an incoming call on your other phone number will go to voicemail if you set up voicemail with your provider.2 However, you won't get a missed-call notification from your secondary number. Call Waiting works for incoming calls on the same phone number. To avoid missing an important call, you can turn on call forwarding and forward all calls from one number to the other. Check with your provider for availability and to find out if additional fees apply.

1. Or if you're using iOS 12. Update to iOS 13 to receive calls when you're using your other number.
2. If data roaming is on for the number that uses mobile data then Visual Voicemail and MMS will be disabled on your voice-only number.

Switch phone numbers for a call

You can switch phone numbers before you make a call. If you're calling someone in your Favourites list, follow these steps:

  1. Tap .
  2. Tap the current phone number. 
  3. Tap your other number. 

If you're using the keypad, follow these steps:

  1. Enter the phone number.
  2. Tap the phone number, near the top of the screen. 
  3. Tap the number that you want to use.

Send messages with iMessage and SMS/MMS

You can use iMessage or SMS/MMS to send messages with either phone number.* You can switch phone numbers before you send an iMessage or SMS/MMS message. Here's how:

  1. Open Messages.
  2. Tap the New button, in the top right-hand corner of the screen.
  3. Enter your contact's name.
  4. Tap the current phone number.
  5. Tap the number that you want to use.

* Additional fees may apply. Check with your provider.

Learn about Dual SIM status icons

The icons in the status bar at the top of the screen show the signal strength of your two providers. Learn what the status icons mean.

You can see more status icons when you open Control Centre.

When Provider 1 is in use, the other line will show No Service. 

The status bar shows that Provider 1 is using LTE and Provider 2 is using Wi-Fi Calling.

With Allow Mobile Data Switching turned on, the status bar shows that Provider 1 is using LTE and Provider 2 is using the mobile data of Provider 1 and has Wi-Fi calling enabled.

Change your mobile data number

One number at a time can use mobile data. To change which number uses mobile data, follow these steps:

  1. Go to Settings.
  2. Tap either Cellular or Mobile Data.
  3. Tap Mobile Data. 
  4. Tap the number that you want to use mobile data. 

If you turn on Allow Mobile Data Switching, then while you're on a voice call on your voice-only number, that number automatically switches to use voice and data.* This lets you use both voice and data while on the call.

If you turn off Allow Mobile Data Switching and you're active on a voice number that isn't your designated mobile data number, then mobile data won't work when you're on the call.

To turn on Allow Mobile Data Switching, follow these steps:

  1. Go to Settings.
  2. Tap either Cellular or Mobile Data.
  3. Tap Mobile Data.
  4. Turn on Allow Mobile Data Switching.

* Your data line switches automatically for the duration of your call. This mobile data switching will not work if you are currently using Data Roaming. Check with your provider for availability and to find out if additional fees apply.

Manage mobile settings

To change your mobile settings for each of your plans, follow these steps:

  1. Go to Settings.
  2. Tap either Cellular or Mobile Data.
  3. Tap the number that you want to change.
  4. Tap each option and set it as you normally would.

Transfer your eSIM from your previous iPhone to your new iPhone

To transfer your eSIM to your new iPhone, you can scan the QR code that your provider gave you, use your provider's iPhone app or install an assigned mobile data plan. When your mobile data plan is activated on your new iPhone, the plan on your previous iPhone will be deactivated.

To set up your new iPhone, follow the steps in the Set up your mobile data plan with eSIM section. If you're asked to "Transfer Mobile Data Plan" during Quick Start setup, follow these steps.

Erase your eSIM

If you need to erase your eSIM, follow these steps:

  1. Go to Settings.
  2. Tap either Cellular or Mobile Data.
  3. Tap the plan you want to erase.
  4. Tap Remove Mobile Data Plan.

If you erase all content and settings from your device, you can choose to erase your eSIM as well or keep it. If you want to cancel your mobile data plan, you still need to contact your provider.
