Using your smartwatch

Use your smartwatch to make calls and surf on the Swisscom mobile network with Multi Device.

Can I also use my smartwatch abroad (roaming)?

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.

Some devices cannot receive a roaming SMS so you may not receive an SMS with the price information for using the device abroad. The costs for use abroad are available in the tariff overview.

How much will I pay for the smartwatch with an Connect Pack or a blue Mobile L and inOne mobile premium?

The Watches & Wearables option is included in these subscriptions and packages, which you can use with both the Apple Watch and the Samsung Galaxy Watch.

I want to give my smartwatch to someone else. What should I do?

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”.

I don’t want to use my smartwatch with Multi Device any longer; what should I do?

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.

My smartwatch has been stolen. What now?

Block your eSIM profile at https://cockpit.swisscom.ch(opens in new tab).

N.B. When you set it up, secure your smartwatch with a personal device code as the device does not have a SIM pin.

Frequently asked questions

Features & costs

You can find an overview of the Multi Device prices and functions at www.swisscom.ch/multidevice

Which mobile subscriptions include Multi Device?

The Multi Device options are available with the blue Mobile S/M/L, inOne premium/basic and Swiss mobile light mobile subscriptions, as well as all SME and older subscriptions (Swiss mobile flat, inOne XS-XL, young).

With blue Mobile L and inOne mobile premium, the Connect Pack and thus the Multi Device Option is included, and you can use your subscription on up to 3 additional devices free of charge.  Additional options can be purchased flexibly. 

Can I use Multi Device together with other people?

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(opens in new tab)) 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.

Can I use WhatsApp and iMessage simultaneously on several devices?

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(opens in new tab) (as at April 2017). iMessage supports Multi Device. 

How much will Multi Device cost with a Connect pack?

With the Connect pack, you can use 3 additional smartphone and/or tablet devices free of charge.

When do I start paying for Multi Device?

The Multi Device option for up to 10 additional devices is only billed when you activate it.

Do I need a PIN for my Multi Device SIM?

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.

Swapping additional device or cancelling Multi Device

How can I change the additional device?

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 on My Swisscom (Customer Center) or – in the opposite case – use a SIM card adapter.

Order a replacement SIM

Micro-SIM Adapter (CHF 4.90)

Nano-SIM Adapter Set (CHF 4.90)

How can I cancel Multi Device?

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(opens in new tab). 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.

What happens with my master device if I change or cancel the Multi Device option.

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.

Where can I add functions and manage use?
