How SOS works on ZOLEO
Know how to connect to emergency response when seconds matter.
A Real Coordination Team, Ready When You Press the Button
A ZOLEO SOS alert isn’t an automated ping into the void. It reaches people whose job is to help coordinate a response.
Seconds Matter. So Does Knowing Who Has Your Back.
When you activate an SOS from your ZOLEO device or the ZOLEO app, the alert goes to Global Rescue, ZOLEO’s emergency response coordination partner.
Global Rescue’s team is experienced in emergency response coordination, having coordinated over 20,000 operations across 200 countries.*
They confirm your alert, receive your location coordinates, and work to get the right help moving.

What Happens When You Activate an SOS?
You activate SOS
Press the covered SOS button on the ZOLEO communicator, or trigger SOS from the ZOLEO app. Your alert is sent with the GPS coordinates of your device.
Your alert is received
Global Rescue receives your alert and location, confirms it, and works to contact the appropriate authorities to help dispatch assistance.
You stay in the loop
With progressive SOS, you receive step-by-step status updates throughout the incident in the ZOLEO app, and can message back and forth with the coordination team.
You receive confirmation
Even when you are using ZOLEO without the app, the device’s LEDs confirm that your SOS message was received. So you’re not left wondering.
What to expect the moment you press SOS
- Your location goes out.
Global Rescue, ZOLEO’s emergency response coordination partner, receives yourGPS coordinates and device battery level. - Updates every six minutes.
Your device keeps sending location updates throughout the incident. - Help is coordinated.
The team confirms your alert and contacts the right authorities to dispatch assistance. - Red LED double-blinks.
On the device, the SOS LED double-blinks red once your alert is confirmed. - You stay in the conversation.
When paired with the ZOLEO app, you get progressive updates and can message the team until it’s resolved.

Help That Talks Back

Paired with the ZOLEO app
Progressive SOS turns a one-way alarm into a two-way conversation. Exchange messages with the emergency response coordination team and follow status updates until your emergency is resolved. No guessing if your message was received.

Without the ZOLEO app
The device still sends your SOS alert to Global Rescue with your GPS location and remaining battery life. Your location updates every six minutes during an active alert, and the SOS LED confirms once your alert has been received.
*Tip: The ZOLEO app also includes Medical Assist: 24/7 non-emergency support for medical questions and minor incidents. It’s a separate service from SOS, for the moments that aren’t an emergency but still need an answer.
