How to set up and use Multi Device
The Multi Device option lets you surf on up to two additional devices and make calls with the same telephone number. So you can take incoming calls on your master device plus additional devices enabled to take calls. And you can make calls on all these devices using the same telephone number. You can also surf on all your devices at the same time. The roaming units in your subscription apply to your master device and additional device(s).

 |
A smartphone with an inOne mobile subscription (except inOne light). This is your master device. |

1 or 2 additional devices that are SIM-only or eSIM. |
