With Multi Device and your inOne mobile subscription you use up to 10 additional devices with a SIM card or an eSIM at the same time. You can still be reached on the same number.
Multi Device three months offered.
You require an inOne mobile subscription to be able to use the Multi Device options.
You don’t need an additional SIM card; simply activate the option directly in the cockpit.
Some devices cannot receive roaming SMS. While travelling, therefore, it is possible that you will not receive any SMS messages with price information for device usage. For information about costs for usage in different countries, please refer to the tariff overview(opens in new tab).
Activate a new Multi Device Watches & Wearables option with a smartwatch and we will waive the option fee of 5.–/mth for the first 3 months. The option will be subject to the standard conditions thereafter. Option requires a current, valid Swisscom mobile subscription (e.g. inOne mobile go, CHF 80.–/mth, minimum contract term of 12 months, activation fee of CHF 49.–). Customers can only take advantage of this promotion once.
