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 thentapping the number whose label you want to change. Then tap Mobile 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 someonewho isn't in your Contacts app. Choose which mobile plans you want to use for iMessage and FaceTime. 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 wantyour 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 numberthat you used the last time you called that contact. If you haven't called that contact, your iPhone will use your default number. You can also specify which numberto 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.

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 If you ignore the call and have voicemail set up with your network provider, you'll receive a missed-call notification and the call will go to voicemail. Check with your network provider for Wi-Fi calling availability and find out whether additional fees or data usage applies from your data provider.

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.³ It could also mean 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.⁴ 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 network provider for availability and to find out whether additional fees apply.

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 the Info button.

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.
