1. Purpose and scope

This Carrier SIM Governance Brief explains how CHERNOMOR uses SIM-card fleets in support of legitimate business internet-traffic operations and how related compliance controls are enforced.

This brief is intended for telecom-carrier, compliance, and risk-review teams evaluating operational purpose, governance posture, and anti-abuse controls.

2. SIM utilization model

CHERNOMOR operates a SIM fleet where cards are installed in physical mobile devices and used to support internet-traffic workloads across approved business use cases.

Higher SIM-card volume supports distribution, continuity, and controlled routing across operational regions while maintaining policy-governed traffic behavior.

• SIMs are assigned to managed physical devices under internal allocation controls.
• Usage is tied to approved operational use cases and monitored for policy compliance.
• SIM lifecycle events (activation, reassignment, suspension) are tracked in internal records.

3. Lawful-use and policy boundaries

• No spoofing, deceptive routing, unauthorized bulk abuse traffic, or policy-violating behavior.
• No use cases that conflict with telecom provider acceptable-use terms or lawful directives.
• Traffic operations remain subject to contractual, regulatory, and carrier policy requirements.

4. Control matrix

1. SIM assignment traceability: each SIM is mapped to responsible operational context and device allocation records.
2. Acceptable-use governance: provisioning and continued use are constrained by documented policy controls.
3. Anomaly monitoring: suspicious traffic patterns and policy deviations trigger review workflows.
4. Escalation and suspension: high-risk indicators can trigger immediate restriction, suspension, or termination actions.
5. Review and evidence readiness: compliance-relevant records are retained for reasonable audit and partner review workflows.

5. Escalation and incident response posture

When suspicious behavior, abuse risk, or policy breaches are detected, CHERNOMOR applies severity-based response procedures including triage, containment, mitigation, and stakeholder communication.

Where required by carrier policy, legal obligation, or regulator direction, immediate control actions may be applied without delay.

6. Disclosure and security limits

To protect network integrity and abuse-prevention effectiveness, this brief communicates governance outcomes and enforcement intent without exposing sensitive internal thresholds, exploitable detection logic, or proprietary operational internals.
