SIM Card Lifecycle

Overview

A SIM moves from provisioning to activation, stays active, may be suspended, and eventually is decommissioned. ICMP treats that path as a state machine, so every transition is explicit. Coverage spans 200+ countries and regions, with 500+ enterprise customers and more than 10 million connected devices on the platform.

States and the rules between them

Moves a SIM through provisioning, activation, active use, suspension, and decommissioning. Transition rules and approvals can be set for each step.

Activate, suspend, and resume

Activates SIMs in a batch, or suspends and resumes a single SIM, and ties those changes to the data plan and roaming policy. That covers a temporary stop or a suspension after non-payment.

Retirement and end of life

Decommissions a SIM, returns it to stock or releases the resource, and keeps a lifecycle audit log for compliance reviews and asset counts.

What lifecycle control has to cover

Operators need one status view worldwide, lifecycle rules that can differ by operator, retention practices that meet GDPR, and an audit trail for every status change. ICMP provides that dashboard, lifecycle reports, webhooks on status changes, batch APIs, and policy settings you can shape to your own rules.

How state changes stay reliable

The lifecycle service is built on a microservices architecture and held to a SLA of 99.9%, with technical support around the clock. TLS protects data in transit, IAM and RBAC control who can change a state, and the audit trail records the change.

Lifecycle sits next to inventory, activation, and diagnostics, so a status change does not live in a separate tool
REST APIs and webhooks so other systems can subscribe to status changes
A history of every transition, useful in an audit or when a SIM looks wrong
A named customer-success manager through rollout and later operations

Situations the state machine covers

Device refresh / project close Decommission SIMs in a batch when devices are scrapped or a project ends, release the resource, and stop billing.

Temporary stop / unpaid accounts Suspend a SIM for non-payment or a planned pause, then resume it after payment or when the pause ends.

Retention rules / SIM recovery At end of life, clear data and recover the SIM according to a retention policy such as GDPR, with the audit log still available.

Putting the state machine into daily use

A typical path is requirements review → solution design → a proof of concept → scaled deployment → ongoing tuning. SimtoLink configures lifecycle policy, writes the transition rules, provides a POC environment, and supports API integration and training.
