Multi Device is intended for individual customers. 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 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. To receive iMessages and SMS on several devices you need to set up your Apple ID in your Apple device settings.
*Multi Device is an additional service for an inOne mobile subscription and requires a special SIM for each additional device. Once activated the Multi Device option cannot be cancelled until the end of the following month (minimum service period). It may then be cancelled at any time, monthly fees being billed on a pro rata basis.
After 12 months without Multi Device option activation or SIM deactivation without re-activation within 12 months, the SIM is invalidated and can no longer be used.
