IoT Connectivity Costs: Managing Thousands of Cellular Lines Without Losing Control

SpendWire Team•3 min read•November 11, 2026

IoT SIM costs range from $1 to $15 per device per month. At scale, poor management wastes hundreds of thousands annually.

The Internet of Things has created a new category of telecom expense that many enterprises struggle to manage. A fleet of 5,000 connected devices at $10 per month each costs $600,000 per year. When those devices are spread across multiple carriers, platforms, and rate plans, waste accumulates rapidly.

IoT Connectivity Pricing Landscape

Carrier Direct Plans

AT&T IoT: $2-15 per device per month depending on data allocation

Verizon ThingSpace: $2-12 per device per month

T-Mobile IoT: $3-10 per device per month

Volume discounts kick in at 500+ devices, with significant breaks at 5,000 and 10,000

MVNO and Aggregator Plans

Hologram: $0.60 per device per month plus $0.40 per MB (pay-as-you-go)

KORE: custom enterprise pricing, typically 20-30% below carrier direct

Aeris: specialized for low-data IoT, $1-5 per device per month

LPWAN Alternatives (for low-data devices)

LoRaWAN: $1-3 per device per year (yes, per year)

Sigfox: $1-15 per device per year

NB-IoT: $1-5 per device per month through carriers

Common Cost Problems

Over-Provisioned Data Plans

An IoT sensor that transmits 5 KB per day does not need a 1 GB data plan. Yet enterprises frequently deploy uniform plans across all devices regardless of actual usage. Right-sizing plans to actual consumption patterns typically saves 30-50%.

Inactive Device Charges

Devices get decommissioned, replaced, or disconnected from the network, but the SIM card keeps billing. A 5,000-device fleet typically has 5-10% inactive SIMs still incurring monthly charges. At scale, that is $30,000-60,000 per year in waste.

Roaming Charges

Devices that cross carrier boundaries or international borders incur roaming fees that can exceed the base plan cost by 10-50x. A single device roaming internationally without a roaming plan can generate $200-500 in monthly charges.

Multi-Platform Fragmentation

Different departments deploy IoT independently. Marketing uses one carrier for digital signage, operations uses another for fleet tracking, and facilities uses a third for building automation. Nobody has a unified view of total IoT connectivity spend.

Optimization Strategies

Consolidate to Pooled Plans

Move all devices to carrier pooled data plans where high-usage devices offset low-usage devices. AT&T and Verizon both offer enterprise IoT pools that reduce per-device costs by 20-40% compared to individual plans.

Implement Lifecycle Management

Track every SIM from activation to decommission. Set automated alerts for devices with zero usage for 30+ days. Suspend rather than cancel unused SIMs (suspension is free with most carriers and preserves the device number).

Match Technology to Requirement

Not every IoT device needs LTE cellular connectivity. Devices sending small data packets infrequently (sensors, meters) can use LPWAN at 90% lower cost. Reserve cellular for devices requiring high bandwidth or real-time connectivity.

Audit Regularly

Run quarterly audits of IoT connectivity spend. SpendWire can ingest IoT invoices alongside traditional telecom and flag inactive devices, plan mismatches, and consolidation opportunities across your entire connected device fleet.

Scale Matters

IoT connectivity management is manageable at 100 devices. At 1,000, it is complex. At 10,000+, it is unmanageable without automated tools. The cost of not managing IoT connectivity grows linearly with device count, but the savings from optimization grow exponentially.
