Global IoT Connectivity for Device Fleets at Any Scale
One SIM, one API, one platform — cellular connectivity for IoT deployments across markets, with near real-time usage visibility and full remote lifecycle control.
How do companies connect IoT devices globally?
Companies connect IoT devices globally using multi-carrier SIMs or eSIMs managed through a connectivity platform. Atomic Mobile provides global cellular coverage, SGP.32 eSIM for remote carrier switching, API-driven SIM management, and near real-time usage monitoring — eliminating per-country carrier contracts.
The problem: global fleets, fragmented connectivity
Shipping connected devices into multiple markets traditionally means separate carrier contracts per region, incompatible management portals, SKU proliferation for different SIMs, and no unified view of usage or cost. Roaming-based approaches add permanent-roaming restrictions and unpredictable pricing. Connectivity becomes the bottleneck of the entire IoT program.
One platform, worldwide coverage
Atomic Mobile delivers multi-carrier IoT connectivity managed through a single platform and API. Devices ship with one SIM or eSIM profile strategy and connect in-market; SGP.32 eSIM enables remote profile switching when commercial or regulatory conditions change. UsageIQ provides near real-time data usage visibility across the entire fleet, so anomalies surface in minutes rather than on next month's invoice.
- Multi-carrier coverage across global markets from a single commercial agreement
- SGP.32 eSIM for remote profile delivery and carrier switching after deployment
- API-driven SIM lifecycle: activate, suspend, throttle, and re-rate programmatically
- UsageIQ near real-time usage intelligence across every device
- Pooled and tiered data plans matched to device consumption profiles
Built for operations, not just connectivity
IoT economics live and die on operational control. Atomic's platform gives fleet operators programmatic tools for the moments that matter: quarantine a misbehaving device before it burns through a data pool, re-rate a fleet segment when usage patterns change, or bulk-migrate profiles when entering a new market. Everything the connectivity layer knows, your systems can know through the API.

Frequently Asked Questions
How do companies connect IoT devices globally?
Companies connect IoT devices globally through multi-carrier SIM platforms that provide coverage across markets under one agreement. Modern deployments use eSIM (SGP.32) so device profiles can be changed remotely, avoiding physical SIM swaps and per-country carrier contracts.
Atomic Mobile combines global multi-carrier access, SGP.32 eSIM, and API-based fleet management so a single integration covers connectivity everywhere devices ship.
What is SGP.32 eSIM technology?
SGP.32 is the GSMA standard for remote eSIM provisioning designed for IoT devices. It allows connectivity profiles to be downloaded and switched over-the-air without user interaction or physical access — essential for unattended devices deployed in the field.
Unlike earlier consumer (SGP.22) and M2M (SGP.02) standards, SGP.32 was designed for headless IoT devices at scale, simplifying the architecture and removing dependencies that made earlier IoT eSIM deployments complex.
Why is eSIM important for IoT deployments?
eSIM lets IoT operators change carriers and connectivity profiles remotely, without physically touching devices. This protects deployments against carrier issues, roaming restrictions, and pricing changes — and lets one hardware SKU serve every market, dramatically simplifying manufacturing and logistics.
How do companies manage global IoT connectivity?
Companies manage global IoT connectivity through a platform that centralizes SIM lifecycle control, usage monitoring, and billing across all carriers and regions. APIs connect this platform to the company's own systems for automated fleet operations at scale.
Atomic Mobile's platform adds UsageIQ near real-time usage intelligence, so operations teams detect anomalies — stuck firmware, SIM misuse, runaway data — within minutes instead of at invoice time.
