SIM Card Inventory

Overview

SIM inventory is how operators keep purchasing, warehousing, allocation, and replenishment on one record. ICMP tracks stock levels, raises reorder alerts, follows lots, and holds a safety-stock buffer. The service covers 200+ countries and regions, supports 500+ enterprise customers, and connects more than 10 million devices.

Stock monitoring

Counts stock by ICCID, lot, region, and customer, including multi-level warehouses, stock in transit, and a board that separates available SIMs from those already allocated.

Reorder alerts

Sets a reorder point from the safety-stock threshold, the burn rate, and the purchasing lead time. When stock falls below that point, an alert can open a work order or call an API to start replenishment.

Lots and allocation

Traces each lot number, allocates or reserves stock, and hands the same record to activation and outbound shipping.

What inventory teams ask for

A cross-border SIM supply chain needs one view of stock in every region, a way to manage cards from several suppliers and operators, data handling that respects GDPR and local storage rules, and a clear picture of turnover and cost. ICMP provides a single global dashboard, inventory reports, replenishment suggestions, and regional pricing that purchasing can work from, and it grows with the volume you hold.

Platform behind the stock record

Inventory runs on a microservices architecture, with a SLA of 99.9% and technical support around the clock. Connections use TLS, sign-in uses IAM, permissions use fine-grained RBAC, and stock movements are written to an audit trail.

Where the stock record is used

Channel distribution / resellers Allocate SIM stock down a multi-level channel, alert when a tier needs replenishment, trace lots, and move stock by region or customer.

Device manufacturing / OEM Hold SIM stock before it is fitted on the line, allocate against the production plan, keep a safety buffer, and connect the record to MES.

Cross-border logistics / overseas warehouses Watch SIM stock in warehouses in several countries, track what is in transit, and use regional replenishment suggestions to cut stockouts.

From first count to steady replenishment

Most projects move through requirements review → solution design → a proof of concept → scaled deployment → ongoing tuning. SimtoLink sets inventory rules, tunes reorder thresholds, provides a POC environment, and helps with system integration and training.
