AT&T detailed the launch in a support document updated today. The carrier explains that Dual SIM and Dual Standby support means you can have 2 active SIMs for one phone, “both ready to go at a moment’s notice.” As for its list of supported Dual SIM and Dual Standby phones, AT&T lists the iPhone XS, iPhone XS Max, and iPhone XR.

AT&T also offers some basic explanation on how Dual SIM phones, including the 2018 iPhone lineup, function:


Choose which number you want to use before sending a text, picture, or video message. Get messages from either number anytime.


Data is only available on 1 number at a time. Normally, you’ll choose the number or account to use for that data session. But, if you’re browsing the web while on a call, you’ll have to use the same number for both activities.

Connected to Wi-Fi®? Your device will use it for both numbers (even if you’re on a call).


Making a call? Choose the number you want to use before you call. Keep in mind: You can’t put a call on hold for 1 number and place a call from the other.

Already on a call? You’ll get a notification for incoming calls on the number you’re using. Incoming calls for your second number go straight to voicemail.

Additionally, Apple keeps a running list of the carriers around the world that support eSIM functionality. In the United States, AT&T is the first major carrier to support the technology. In Canada, eSIM is supported by Bell, Fido, Lucky Mobile, Rogers, and Virgin Mobile.

Across Europe, eSIM functionality is far more widespread, as is also the case in the Asia-Pacific, the Middle East, and India. Read Apple’s full list of supported carriers in each region here.
