What happens when the power goes out - can you still make calls? From March 2026, new rules apply in Switzerland: Mobile providers must ensure their networks work even during power outages.

In this article, you'll learn what new regulations apply, what the implementation looks like, and how you can personally prepare.

✅ New FDV Regulation from March 1, 2026The revised Telecommunications Services Ordinance (FDV) requires mobile providers to protect their networks against power outages. Emergency calls must remain possible even during blackouts.

The Problem: Mobile Networks Without Power

During a large-scale power outage, not only do the lights go out - mobile masts also need electricity. Without backup power, the mobile network collapses within minutes.

Backup Power	Voluntary, inconsistent	Legally required
Minimum Bridge Time	A few minutes	At least 1 hour
Emergency Call Priority	Not guaranteed	Prioritized
Complete Coverage	-	By 2031/2034 gradually

The New FDV Requirements in Detail

Implementation Timeline

Date	Requirement
March 1, 2026	New FDV takes effect
2026-2028	Expansion of backup power in urban areas
By 2031	80% of population covered

Technical Requirements

Providers must:

Install batteries or UPS at mobile masts
Ensure at least 1 hour bridge time

Frequently Asked Questions

Yes, as long as your phone battery is charged and the mobile masts near you have backup power. From 2026, providers must guarantee at least 1 hour of bridge time.

What About Landline Phones?

Classic analog landline phones often still work briefly during power outages. However, IP telephony (Voice over IP) requires power for routers and phones.

Can I Make Emergency Calls Abroad Too?

Yes, 112 works in all EU countries and many other nations - even without a SIM card inserted.

What Does the Federal Government Do During a Large-Scale Blackout?

The FOCP (Federal Office for Civil Protection) coordinates crisis communication. Sirens, radio, and Alertswiss inform the population.
