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).
With Multi Device, both residential and SME customers can make calls and surf over the Swisscom mobile phone network with smartwaches.
Although Multi Device supports roaming, it is not supported by the Apple Watch outside the Swisscom mobile network. However, you can pair your Apple Watches with your iPhone (Bluetooth) or use the WLAN function aboard.
By contrast, the Samsung Watch Galaxy supports international roaming and can thus be used abroad to its full extent.
All inOne mobile L and XL subscriptions include a Watches & Wearables option, which you can use with both the Apple Watch and the Samsung Galaxy Watch.
Apple Watch: Open the “Apple Watch” app on your iPhone, tap “My watch” and then tap the top of your Apple Watch display. Tap the “Info” button and then on “Unpair Apple Watch”.
Samsung Watch: Go to “Settings”, then “General” and “Reset”.

N.B. When you set it up, secure your smartwatch with a personal device code as the device does not have a SIM pin.
You have to remove the device in the Swisscom Cockpit to cancel the monthly Multi Device costs.
Once activated the Multi Device option cannot be cancelled until the end of the following month. After that, you can cancel the Multi Device option whenever you like. Costs are billed on a pro rata basis.
When you transfer a contract, the Multi Device option is always cancelled. The smartwatch can no longer be used on its own without the main device.
You can find an overview of the Multi Device prices and functions for master devices and additional devices at www.swisscom.ch/multidevice
No. Multi Device is intended for the personal use of one person only. All devices can be reached using the same telephone number. Anyone with access to your additional device can use your services at home and abroad and has access to the Cockpit (cockpit.swisscom.ch) for example. They can make changes to the settings for your devices there. We recommend the new inOne products for people in the same household.
Swisscom assumes no liability or guarantee for the function of third-party services (such as third-party instant messaging or apps) with Multi Device. WhatsApp currently only supports the use of WhatsApp accounts with one number on one device (as at April 2017). iMessage supports Multi Device.
You can check current costs and inclusive units in the Customer Center and in the Cockpit for your subscription. Usage is not broken down by device.
No, with every Multi Device SIM the SIM PIN is deactivated by default. The reason for this is that it is not possible to enter a PIN for additional devices without a display (e.g. tracker or camera).
Note: If you receive your Multi Device SIM, you will still find a PIN printed on the SIM cardholder. This is required, should you want to reactivate the PIN. Insert the SIM into the device and activate the SIM PIN in the settings. Use the PIN on the SIM cardholder. After initial entry, the PIN can be changed as desired.
The Multi Device option for up to 10 additional devices is only billed when you activate it.
You can take your time with the activation. The SIM becomes invalid:
You can manage this function in the device settings of your additional device in the Cockpit. You can access the Cockpit from your master or additional device.
To make calls on an additional device, your device has to support this feature. You also need to activate the “Calls” setting for the specific additional device in the Cockpit at cockpit.swisscom.ch.
You can simply remove the Multi Device SIM from your additional device and place it in your new additional device. If the SIM is too large for your new additional device you can order a replacement SIM in the Customer Center or – in the opposite case – use a SIM card adapter.
There is a minimum service period for Multi Device.
Once activated, the Multi Device option cannot be cancelled until the end of the following month. When the minimum service period has expired, the Multi Device option can be cancelled at any time without compensation. When deactivating, the Multi Device option is immediately deactivated via the Cockpit. When it is deactivated, the monthly fee is charged pro rata.
When the main contract is cancelled (the existing inOne mobile contract for the master device), the Multi Device option is also cancelled automatically.
The master device is unaffected.
The functions of your master device and the services included in your inOne mobile subscription can still be used as normal.
The SIM can still be used to activate Multi Device. The SIM becomes invalid after 12 months
For replacement cards, visit a Swisscom Shop close to you or oder it online.
