Permanent roaming exposes IoT devices to unpredictable networks and weakens security controls. Devices may connect through untrusted carriers, increasing the risk of interception, misconfigured routing, and regulatory non-compliance. Enterprises should avoid relying on permanent roaming by using global SIM solutions with private networking and Zero Trust security.
Why permanent roaming matters
Permanent roaming happens when an IoT device connects to a foreign network for long periods instead of its home operator. While it can seem like a shortcut to global connectivity, it introduces several security and compliance risks:
-
Untrusted networks – devices may connect via third-party carriers without enterprise-grade security.
-
Inconsistent encryption standards – not all networks enforce the same level of protection.
-
Exposure to attacks – devices remain on public internet routes, making them easier targets.
-
Data residency issues – GDPR and regional laws may prohibit long-term roaming.
-
Limited visibility – enterprises lose insight into how traffic is routed and secured.
How to reduce these risks
-
Use a global SIM with multi-network access – ensures devices connect locally with strong redundancy.
-
Adopt private networking (SecureNet) – isolates IoT traffic from the public internet.
-
Enforce Zero Trust principles – eliminate exposed IPs and authenticate every connection.
-
Centralize SIM management – gain visibility and control through a Connectivity Management Platform (CMP).
