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.

Frequently Asked Questions

Which is better — ZOLEO or Verizon satellite?

What satellite system is Verizon using?

It depends on the phone family: certain Android devices use Skylo for satellite connectivity; supported iPhones use Globalstar for Emergency SOS via satellite. 

Does Verizon satellite cost extra?
