Will you get emergency alerts on a foreign phone in Denmark?

Phone warnings for visitors.

Answered at: Checked at:

Short answer

Yes, if your phone is compatible. S!RENEN, the Danish mobile warning system, sends warnings to all compatible phones in a danger area, whether or not they have a Danish SIM card. As of November 2026 that means an iPhone 8 or newer with iOS 16.4 or newer, or an Android phone with Android 11 or newer. Warnings are sent in Danish and English, and you do not need to sign up or download an app.

Practical info

Why

  1. Tourists in a danger area are warned too.
  2. No registration or app is needed.
  3. Warnings come in English as well as Danish.

Details

A warning comes with a distinct sound and vibration that differs from text messages and push notifications.

Tip

When a warning arrives, follow the instructions in it: stop, read, react.

What may differ

Older phones or phones without updated software may not receive the warnings.

Common misconception

You need a Danish SIM card or a special app to get emergency warnings in Denmark.

What actually happens

S!RENEN reaches compatible phones in the danger area without a Danish SIM and without an app.
