Enterprise Connectivity
The right specification, managed as infrastructure.
Physical SIM remains the correct specification where device hardware, environmental conditions, lifecycle requirements, or protocol constraints demand physical connectivity. Boundless provides physical and industrial SIM connectivity as an enterprise programme — not a product order — on the same carrier-agnostic, multi-network infrastructure as Enterprise eSIM.
When physical SIM is the required SIM credential format
Not every device supports eSIM. Not every deployment environment allows it. Physical SIM — across standard, industrial, and soldered MFF2 form factors — remains the required SIM credential format for a significant portion of enterprise device estates. Boundless manages this as infrastructure, not as a product sale.
The same programme, every form factor
Whether your fleet uses standard nano-SIMs, industrial-grade MIM cards, or soldered MFF2 chips, the underlying programme is the same: carrier-agnostic, centrally governed, and managed on the same infrastructure as our Enterprise eSIM offering. Form factor changes. The governance doesn't.
SIM Form Factors
The right form factor for the right device
Physical SIM requirements are determined by device hardware, environmental specifications, and lifecycle requirements. Boundless programmes span all standard enterprise form factors.
Standard SIM
Removable SIM formats for enterprise devices where standard physical connectivity is the correct specification.
Standard
Mini-SIM (2FF)
Legacy standard form factor — still used in specific industrial and commercial device categories.
Standard
Micro-SIM (3FF)
Reduced-size SIM for compact commercial devices where standard connectivity applies.
Standard
Nano-SIM (4FF)
Current standard form factor for the majority of commercial enterprise mobile devices.
Industrial SIM
Ruggedised SIM formats for long operational lifecycles in environments where standard commercial SIM cards may not be appropriate.
Industrial
Industrial MIM (Machine Identity Module)
Ruggedised SIM designed for extended operational temperature ranges, vibration, and environmental exposure — appropriate for industrial machinery, fleet telematics, and infrastructure monitoring deployments.
Industrial
Hardened SIM
Rated for operation across extreme environmental conditions — including temperature variance, humidity, and mechanical stress — for deployments in demanding physical environments.
MFF2 — Machine Form Factor 2
The MFF2 (soldered) form factor is a chip-scale SIM soldered directly to the device PCB at manufacture. It removes the need for a removable SIM socket and helps reduce connector-related failure risk — making it appropriate for high-reliability or long-lifecycle deployments where physical SIM replacement is not operationally feasible.
MFF2
Soldered Connectivity
MFF2 chips are soldered directly to the PCB at manufacture, removing the SIM socket entirely. Connectivity credentials are managed remotely — provisioning, profile switching, and lifecycle management are all handled through the Boundless management platform without physical access to the device.
Deployment
Appropriate Use Cases
MFF2 is appropriate for devices deployed in physically inaccessible locations, high-vibration environments, or situations where device tamper-resistance is a hardware requirement. Common deployments include utility infrastructure, vehicle telemetry, remote sensors, and long-lifecycle industrial devices.
Network Coverage
The same carrier-agnostic coverage, every form factor.
Physical and industrial SIM programmes operate on the same carrier-agnostic, multi-network infrastructure as Enterprise eSIM. Carrier selection is not determined solely by a single operator relationship — access to multiple networks per region provides coverage continuity across geographies where single-carrier coverage would be insufficient.
Coverage and network access figures are indicative and subject to regional conditions, carrier agreements, and applicable regulatory requirements.
One Programme · All Form Factors
The same infrastructure. The same secure architecture options. The same governance.
Every physical SIM form factor — standard, industrial, or MFF2 — is governed on the same carrier-agnostic, multi-network infrastructure. One programme. One management environment. One governance framework.
Carrier-Agnostic Infrastructure
Physical and industrial SIM programmes operate on the same carrier-agnostic infrastructure as Enterprise eSIM. Network selection is not determined solely by a single carrier relationship — access to multiple networks per region is built into the programme architecture.
Secure Architecture Options
Private APN options, data routing controls, and access policy management are available across all physical SIM form factors. Security posture is structured at the programme level — not determined solely by the device form factor.
Unified Governance Framework
All physical and industrial SIM connections — regardless of form factor — are managed through the same central platform environment. Provisioning, lifecycle management, spend visibility, and policy controls operate consistently across your entire fleet.
Coverage and network access figures are indicative and subject to regional conditions, carrier agreements, and applicable regulatory requirements.

Why physical SIM programmes are structured as infrastructure
Specification-Matched Connectivity
Every SIM form factor selected specifically for your device and deployment context — hardware constraints, environmental specifications, and lifecycle requirements determine the specification. Not the other way around.
Continuity Across Mixed Deployments
Organisations managing device estates with multiple SIM types — standard, industrial, and MFF2 — operate all connections through the same programme governance framework. One management environment, regardless of form factor mix.
Unified Estate Management
Central provisioning, visibility, and estate management across all physical SIM connections — regardless of form factor, geography, or deployment context.
Long-Lifecycle Programme Design
Physical and industrial SIM programmes are designed for the lifecycle realities of embedded and industrial deployments — where devices may be in service for years and physical SIM replacement is operationally constrained.

Deployment & Lifecycle
Managed as infrastructure, not as a product order
Physical and industrial SIM programmes are structured for enterprise procurement cycles — from specification through to long-term lifecycle governance, with remote provisioning and centralised management at every stage.
Structured Procurement
Physical SIM programmes are structured for enterprise procurement cycles — not retail ordering. Commercial frameworks align to deployment scale and organisational requirements.
Centralised Provisioning
Fleet-level provisioning from initial activation through lifecycle management, while reducing the administrative overhead that comes with individual device administration at scale.
Estate Management
Full connection lifecycle management — activation, profile management, suspension, and retirement — managed through the same platform environment as your eSIM fleet where applicable.
Scalable Fleet Management
From initial deployment through fleet expansion, the programme scales without structural changes — visibility, governance, and commercial structure designed for long-term operational continuity from initial deployment.
How We Work Together
From specification to deployment
Physical and industrial SIM programmes begin with a structured discovery process — scoping device requirements, environmental constraints, and lifecycle considerations before any specification is confirmed.
Scope the Device Estate
We begin by understanding device types, hardware constraints, environmental requirements, deployment geography, and fleet scale.
Confirm the Specification
The correct SIM form factor is confirmed based on device hardware, operational environment, and lifecycle requirements — not assumed.
Structure the Programme
We establish the commercial framework, management architecture, and estate governance structure appropriate to your deployment.
Deploy & Govern
Controlled deployment with centralised provisioning management, so that connectivity credentials and configurations are confirmed correct before the next activation phase. Governance can be maintained during transition and scoping where operationally required.
Designed for minimal disruption. Physical and industrial SIM programmes are structured around your existing device estate and operational priorities.
