June 7th till June 9th 2022 Maintenance Work SMS System

7. - 9. June 2022, all mobile numbers except of German mobile numbers

During the night of June 7th from 11pm-5.30 am as well as on June 8th from 11pm-5.30 am, maintenance work will be carried out on the Swiss SMS system, which also sends SMS for Swisscom Trust Services to all mobile customers except those with a German mobile number. As all components are redundant, there should be no restrictions in operation at any time. Nevertheless, experience shows that an SMS can sometimes be lost in a switchover moment.
