Device Management
Cellusys Device Management gives operators precise, remote control over their devices and SIM estate. From over-the-air SIM updates to service entitlement enforcement, the platform ensures operators can manage the full lifecycle of connected devices efficiently and at scale.
Operator challenges
- Physical SIM management is expensive and operationally complex at scale
- Rolling out new services requires coordinated updates across millions of devices
- Ensuring only eligible devices access restricted services such as VoWiFi, VoLTE, and eSIM
- Managing diverse device ecosystems including consumer, IoT, and MVNO subscribers
- Maintaining security and compliance across over-the-air communication channels
How the platform works
The OTA Server delivers SIM commands and service payloads to devices over secure channels — both SMS-based OTA for broad compatibility and BIP over HTTPS for high-speed delivery in LTE and 5G environments. Operators schedule and target campaigns through a centralised management console.
The Entitlement Server sits in-line with device service requests, validating eligibility in real time against subscription data, device capabilities, and operator policy. It integrates with HSS, HLR, and BSS to ensure decisions reflect current subscriber state.

Deployment
Both OTA Server and Entitlement Server can be deployed on-premises or in the operator's cloud environment. The platform supports multi-tenancy for MVNO hosting and scales linearly from single-operator to large-scale deployments.
Integration with existing BSS, HSS, HLR, and SMSC infrastructure is handled through standard interfaces. Professional and managed service options are available for operators requiring hands-on deployment support.
