All devices combined in one Mobile subscription. 

Multi Device is a supplementary service to a blue Mobile or inOne mobile subscription and requires a special SIM card for each additional device. Multi Device is available in Trackers & Sensors, Watches & Wearables and Smartphones & Tablets versions (categories). There is now also the Cars & Mobilities option that can be used with various BMW models. Once the additional device has been activated for a given category, this applies for a minimum service period until the end of the following month. After this, this Multi option category can be terminated at any time, with the monthly fees charged pro rata.

If a Multi Device option has not been activated for twelve months or the SIM is deactivated without being activated again within twelve months, the SIM becomes invalid and can no longer be used.

Restrictions:

• It is not possible to make calls on the main and additional devices at the same time.
• SMS/MMS cannot be sent and received on the additional device.
• Once the 40/80/120 GB capacity for the additional devices in the Smartphones & Tablets Multi Device option has been used up, Multi Device users can continue surfing on the additional device for free at a reduced speed.
  
• The additional device can be used as part of the available roaming credit (days/data volume) for the respective inOne mobile subscription. When roaming, the usage is deducted from the inclusive volume of the main blue Mobile connection. If the main device and additional device are used on the same day, only one roaming day is charged.
  
• Multi Device is intended for personal use by a single individual.
• Parallel use of Multi Device at different locations and use of mobile hotspote is not permitted.
• Swisscom is entitled to block the connection immediately if the Multi Device SIM is misused or if there are indications of misuse.
  
• Swisscom assumes no liability or warranty for third-party services (such as instant messaging or third-party apps) and the functionality of these third-party services with Multi Device.
  
• Device is not offered for Liechtenstein connections with a +423 prefix.
  
• The use of connected devices (e.g. Apple Watch, TLC30 Watch, MoveTime, trackers, etc.) may require the customer to accept the terms and conditions of use of third parties (device manufacturers and app and web service providers). Swisscom recommends that you read the terms and conditions of use of these third parties carefully and that you find out about data protection and security aspects in particular.
