Every Olarm device requires an active subscription to function. This isn’t just about the SIM cards, it’s about keeping your device connected, secure, and fully supported.
Dual SIM connectivity (multi-network for better coverage)
Mobile data and secure server access
SIM admin and backend management
Even if you're using Wi-Fi, the subscription still matters. Wi-Fi is just one connection method in your ecosystem. The core connection, and the one Olarm relies on most, is GSM/LTE via built-in Olarm-managed SIM cards.
Your subscription pays for more than just SIM data. It covers the entire infrastructure behind your device: server communications, remote management, and continuous updates.
The Olarm SIMs are custom-managed. Replacing them with your own SIMs will break functionality and void your warranty.
