Use two phone numbers for calls, messages, and data

Now that your iPhone is 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 uses the same number that you used the last time you called that contact. If you haven't called that contact, your iPhone uses your default number. If you want to, you can specify which number to use for your calls with a contact. Follow these steps:

Tap the contact.
Tap Preferred Cellular Plan.
Tap the number you want to use with that contact.

Make and receive calls

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

With iOS 13 and later, when you're on a call, if the carrier for your other phone number supports Wi-Fi calling, you can answer incoming calls on your other number. You will need to turn on Allow Cellular Data Switching when you are on a call that isn't your default data line. Or, if you ignore the call and you have voicemail set up with your carrier, you’ll get a missed-call notification and the call will go to voicemail. Check with your carrier for Wi-Fi calling availability, and find out if additional fees or data usage applies from your data provider.

If your carrier doesn't support Wi-Fi calling or you don't have Wi-Fi calling turned on,¹ then when you're on a call, an incoming call on your other phone number will go to voicemail, if you have voicemail set up with your carrier.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 carrier for availability and to find out if additional fees apply.
