Setting up and using Multi Device 

On this page:
Set up Multi Device, use it with Smartwatches and clarify other service-related questions. 

What is Multi Device?

With the Multi Device option you can use the same phone number on up to 10 additional devices (up to 3 "Smartphones & Tablets", up to 3 "Watches & Wearables" and up to 4 "Trackers & Sensors"). So you can take incoming calls on your master device plus additional devices enabled to take calls. And you can make calls on these devices using the same telephone number. You can also connect all your additional devices to the Internet at the same time.

 

You can also use your main and additional devices abroad: your roaming allowance applies to both your master and additional device(s) (with the exception of the Apple Watch).
