1. Scenario Overview
SIM lifecycle follows the timeline of an IoT SIM: stock-in, activation, in service, suspend and resume, renewal at expiry, and retirement. SIM Status Monitoring watches live health and exceptions. This page covers stage definitions, status transitions, and renewal at expiry: which stage a SIM is in, when it should renew, and when it can be reclaimed, so inventory and spare stock stay planned.
You can define your own stages and the rules that move a SIM between them. Each status change is kept on record. Reminders go out at several points before expiry, and auto-renewal can be turned on so a forgotten renewal does not take the SIM offline. Counts by stage — stock not yet activated, in service, nearing expiry — feed purchasing and reclaim decisions.
2. Core capabilities
Stages and transition rules
Stock-in, activation, in service, suspend and resume, expiry, and retirement can each be configured. A SIM sits in one stage at a time, and a stage change can start business logic such as billing after activation. You set the allowed moves: activation to in service, in service to suspend and back, expiry to retirement. Every move is stored for audit and risk review.
Renewal and reminders
Reminders can fire at several points before expiry, for example 30, 7, 3, and 1 day out, by SMS, email, or in-app message. Auto-renewal renews the data plan when it expires, so a missed reminder does not stop service. The payment method has to be on file first.
Stage counts for decisions
See how many SIMs, and what share, sit in each stage: stock not activated, in service, nearing expiry, suspended, or retired. Low stock points to a replenishment buy. SIMs that expired without renewal are candidates to reclaim. Export by those dimensions when you plan inventory.
Change history and archive
Each stage change is kept so audit and risk review can follow it. Retired SIMs can be archived and dropped out of active counts. Transition rules can set the trigger: activation moves the SIM into service, and expiry moves it toward an upcoming suspension.
3. Lifecycle Process
4. Lifecycle and status monitoring
The two jobs stay separate. The differences are:
| Dimension | SIM lifecycle | SIM status monitoring |
|---|---|---|
| What it watches | The timeline: which stage the SIM is in, and when it should renew | Live health: current status, remaining data, and exception alerts |
| Typical capabilities | Stage definitions, transition rules, renewal at expiry, stage counts | Dashboards, highlighted exceptions, alert rules, and a status overview |
| What it informs | Purchasing, reclaim, and inventory planning | Live operations and exception handling |
Use them together: lifecycle sends the renewal reminder, and status monitoring catches a live exception. Stage names and transition conditions can be renamed to match how your operation defines a SIM.
5. Where teams use it
- Inventory: Count SIMs that are not activated, in service, nearing expiry, suspended, or retired, then decide what to buy and what to reclaim.
- Renewal reminders: Notify at 30, 7, 3, and 1 day before expiry so a missed date does not take the line down.
- Auto-renewal: Renew the data plan at expiry for customers who stay on the same plan, and cut the manual chase.
6. What changes in daily operations
A SIM timeline makes the next action obvious. Expiry reminders cut downtime. Stage counts show where to buy and where stock is sitting idle. Change history answers an audit question without a spreadsheet hunt. Auto-renewal removes a recurring manual step. Pair it with SIM Status Monitoring: lifecycle owns the stage, monitoring owns the live alert.
7. How to put it in place
Name the stages and the allowed moves first, then set the reminder thresholds. Review the count in each stage on a regular cadence and adjust purchasing from that. Several reminders before expiry catch the cases a single notice misses. Auto-renewal fits customers who stay on one plan, and it needs a payment method stored ahead of time. Export the stage counts for not activated, in service, nearing expiry, suspended, and retired when finance or warehouse asks for a snapshot.
