The inOne mobile subscriptions apply for normal personal use and primary use within Switzerland. Outside of Switzerland, subscriptions apply for normal personal use while travelling and during temporary stays abroad. Swisscom reserves the right to curtail or restrict the service or take other appropriate steps if it establishes that usage deviates significantly from the norm (e.g. use primarily outside of Switzerland), or if there are justified indications that the SIM is being used for special applications (e.g. surveillance applications, machine-to-machine, direct dial or continuous connections).
