When Survival Matters, ZOLEO Does What Your Phone Can’t

ZOLEO was purpose-built for no-compromise safety worldwide: a physical SOS button, long battery life, rugged design, and global Iridium coverage — plus unlimited Check-Ins and opt-in automatic location sharing with LocationShare+ to keep your loved ones informed.

ZOLEO Delivers True Global SOS Reliability
ZOLEO devices connect through the Iridium® satellite network, delivering seamless coverage everywhere on the planet — land, sea, or sky. That means your SOS function works no matter where you are.
By comparison, Verizon’s new satellite service is limited to the Continental US, Hawaii, and Alaska. If you travel internationally, your phone’s satellite SOS function simply won’t connect.
With ZOLEO, coverage is not dependent on where cell towers reach or which latitude you’re standing in. When it matters most, you need a device that’s purpose-built for emergencies and works anywhere on Earth.
How ZOLEO Progressive SOS Works
With ZOLEO, it’s easy to trigger an SOS in the case of an emergency. Progressive SOS by ZOLEO is easy to use, providing immediate, reliable SOS alerting and ongoing communication with emergency responders until help arrives.
