Validity API — SIM Plan Status and Expiry Checking
Overview
ISIMConnect’s Validity API is a REST API that retrieves the current plan status, remaining active period, and data balance of ISIMConnect-provisioned SIM cards — allowing enterprise platforms to monitor SIM plan health, trigger renewal workflows, and prevent service interruption before SIM plans expire. It queries real-time plan data directly from the operator’s billing system for Airtel, Jio, Vodafone, and BSNL SIMs.
What is a Validity API?
A Validity API is a connectivity verification service that allows businesses to instantly check SIM card status, validate subscriptions, and verify whether a SIM card, M2M SIM, or eSIM profile is active and operational.
Instead of manually checking each SIM chip, organizations can automate the process and receive real-time status information directly within their business applications, management platforms, or connectivity dashboards.
This solution is particularly valuable for companies using:
M2M SIM cards
SIM IoT devices
Asset tracking systems
Fleet management platforms
Smart city infrastructure
Industrial monitoring equipment
Connected healthcare devices
Enterprise mobility solutions
By automating SIM management, businesses can reduce operational costs and improve device uptime.
What the Validity API Returns
Plan status – Active / Inactive / Expired
Plan expiry date – Date and time the current plan expires
Remaining data balance – Current data allowance remaining (where applicable)
Plan name – The operator plan currently active on the SIM
Auto-renewal status – Whether the SIM plan is set for automatic renewal
How the ISIMconnect Validity API Works
Your application sends a request through the API.
The API performs a check SIM operation against the connectivity database.
The platform verifies the current SIM validity and connectivity status.
A response is returned with the latest SIM status information.
Businesses can automate workflows, alerts, reporting, and device monitoring based on the result.
This automated approach helps organizations monitor thousands of SIM cards without manual intervention.
Key Features of ISIMconnect Validity API
Real-time query — retrieves current plan data from the operator, not a cached snapshot
Query by ICCID, MSISDN, or IMSI
Bulk validity check — query status of multiple SIMs in a single API call
Threshold alerts — configure API-driven alerts when remaining validity falls below a set threshold
Supports Airtel, Jio, Vodafone, and BSNL from a single API endpoint
Benefits of Using a SIM Validity API
Reduce Connectivity Downtime
Detect inactive or expired SIM cards before they impact operations.
Improve Device Visibility
Monitor the health and connectivity status of devices connected through M2M SIM cards, eSIM cards, and enterprise connectivity solutions.
Simplify SIM Management
Automate repetitive SIM management tasks and reduce manual verification efforts.
Support Business Automation
Create automated workflows based on SIM status, connectivity events, and subscription lifecycle information.
Increase Network Reliability
Maintain continuous access to your mobile network by proactively monitoring SIM validity.
Better Customer Experience
Ensure devices remain connected and operational, improving service delivery and customer satisfaction.
Common Use Cases
Automated renewal triggering: Monitor SIM validity and automatically trigger plan renewal via the operator or ISIMConnect platform before expiry
Fleet health monitoring: Bulk-check plan status across a SIM fleet to identify expiring SIMs before they cause device connectivity failures
Customer billing integration: Integrate SIM plan status with enterprise billing systems — link IoT service billing to underlying SIM plan status
Alerting and operations: Send alerts to operations teams when a critical SIM’s plan is approaching expiry
Onboarding validation: Confirm plan is active before marking a device as live in a deployment dashboard

Frequently Asked Questions
Q: What does ISIMConnect’s Validity API check?
A: It retrieves the current plan status (active/inactive/expired), expiry date, remaining data balance, and plan name for an ISIMConnect SIM card — queried in real time from the operator’s billing system.
Q: Can I check validity for SIMs on all four operators from the same API?
A: Yes. ISIMConnect’s Validity API queries Airtel, Jio, Vodafone, and BSNL SIMs from a single endpoint — operator is determined by the SIM’s ICCID.
Q: Can I set up automated alerts when a SIM is about to expire?
A: Yes. The Validity API supports threshold-based alert configuration — trigger a callback or notification when remaining validity falls below a defined number of days or data balance falls below a defined threshold.
