Cell Alert in Switzerland: 16 million approved (cross-border guide)

Context

In a nutshell

• Commitment credit of CHF 15.8 million for cell broadcast system
• Urgent SMS alert to mobile phones in the affected area
• Implementation timeline from 2027 to 2035

Key facts

• What: Cell broadcast alarm system that sends SMS to phones
• When: Credit application in 2026; implementation 2027–2035
• Where: All of Switzerland
• Who: Federal Council to Federal Parliament
• Amount: 15.8 million CHF commitment credit; 67.7 million total 2027–2035
• Infrastructure: at national telephone operators
• Support: Cantons and Parliament have requested acceleration

The Federal Council has sent Parliament a request for a commitment appropriation of CHF 15.8 million to implement a new alarm system called "cell broadcast". This system allows you to send short text messages directly to mobile phones in an affected area in the event of an alarm or urgent alert.

Unlike sirens, which reach an audience limited to urban areas, cell broadcasting offers widespread coverage of the national territory through the infrastructure network of telecommunications providers. The new channel complements and reinforces the civil protection devices already in operation: traditional sirens, radio releases subject to the broadcasting obligation, as well as the Alertswiss website and app, which have been active since 2018.

# How cell broadcasting works nationwide

Cell broadcasting represents a significant evolution in the federal civil protection strategy. Unlike alarm sirens, which require geographical proximity and direct visibility to function effectively, the cell broadcast sends short, automatic text messages directly to the mobile phones of those in the affected area at that specific time.

This approach does not require the receiver to have a special subscription, to have installed an app, to have activated a notification service or to be listening to a radio. The system operates at the national telephone network infrastructure level: when a federal or cantonal authority authorizes the sending of an alarm, the text message automatically reaches all phones connected to the telephone cells in the affected area, regardless of the network provider chosen.

Multi-channel integration: redundancy and resilience

The strategic importance of cell broadcasting lies not in the replacement of existing systems, but in their integration. The sirens remain operational for immediate visual and auditory alarm in urban and peri-urban areas. Radio announcements subject to the broadcasting obligation continue to provide detailed and contextual information on an ongoing alarm. The Alertswiss app, active since 2018, allows residents to proactively search for alarm information

Key points

The request for credit from the Federal Parliament is the first concrete step towards the operation of cell broadcasting in Switzerland. The schedule indicated in the federal documentation provides for full implementation between 2027 and 2035, with a progressive setting up of the infrastructure at national telephone operators. The exact timing will depend on the completion of the parliamentary credit approval procedure and the technical time required for the construction of the infrastructure at the suppliers.

What to do and what to expect

Residents and workers in Switzerland will not have to take any explicit action to benefit from cell broadcasting. Unlike other alarm services that require manual registration or activation, the broadcast cell will work automatically by activating the mobile phones of those in the affected area at the time of the alert. You will not need to download additional apps, subscribe to specific subscriptions, or check security settings: the message will arrive on all devices connected to the affected phone cells, regardless of the mobile network provider and the tariff plan chosen.

Once Parliament approves the commitment appropriation, the relevant federal offices will proceed with the conclusion of contracts with telephone operators and with the start of technical development. This decision represents an investment consistent with the multi-channel strategy of
