An eSIM is a digital SIM profile that can be provisioned and managed remotely, without a physical SIM card. For IoT, this means activating, updating, and managing connectivity across devices without manual handling.

Are eSIMs the same as embedded SIMs?

Not exactly. An embedded SIM is a physical chip soldered into the device. An eSIM refers to the eUICC technology that enables remote profile management on that chip. NexCon works with both.

What's the difference between consumer eSIM and IoT eSIM?

Consumer eSIM is designed for phones and tablets. NexCon's eSIMs are built for IoT: remote provisioning, operational rollouts, and lifecycle management across connected devices at scale.

Can one generic QR code be used across many devices?

Yes. NexCon's generic QR code and link-based setup is designed precisely for scalable onboarding: one code, many devices.

Can eSIMs be provisioned via QR code, API, or dashboard?

Yes, all three. Choose the provisioning flow that fits your deployment and workflows.

Do NexCon eSIMs support NB-IoT and LTE-M?

Yes, where supported by the deployment setup and network requirements.

Can we manage activation and deactivation ourselves?

Yes. Through the NexCon eSIM management platform, you control activation, deactivation, and key lifecycle actions directly.

Is this suitable for large rollouts?

Yes, the generic, scalable eSIM model is built exactly for that. The more devices involved, the more time and complexity it saves.

When physical SIM logistics become the bottleneck

Physical SIM cards work well for many IoT deployments. But in distributed rollouts, post-shipment activation, end-user onboarding or frequent field changes, the logistics around removable SIMs can slow things down.

Activation can't always wait for logistics

When devices are shipped to different countries or customers, waiting for physical SIM handling slows down rollout unnecessarily.

Field changes are expensive

Updating or replacing a SIM after deployment means sending someone on-site — time and cost that adds up fast at scale.

Onboarding shouldn't require manual intervention

For large rollouts across distributed teams or locations, physical SIM handling creates bottlenecks that are hard to avoid.

Remote activation, full flexibility. Managed from one eSIM management platform.

Here's how it works

From initial setup to live devices in five straightforward steps.

Step 1 / 5

Define your deployment

Specify your use case, hardware, target countries, and preferred onboarding flow.

What your business gains when physical SIM complexity disappears

Simpler operations, faster rollouts, and a fleet that's always under control.

Faster deployment

Activate connectivity remotely instead of waiting for physical SIM logistics. Rollouts that used to take weeks happen in days.

Less manual work

No SIM insertion, no field replacements, no country-specific SKUs. eSIM removes the operational friction that builds up as deployments grow.

More flexible lifecycle management

Update profiles remotely, activate connectivity after shipment, and adapt to changes without sending anyone into the field.

Simpler scaling

Standardize hardware across markets. One device. One setup. Ready wherever you need it.

Where eSIMs make the biggest difference

From logistics to hardware to wearables. Here's how NexCon eSIMs work in the real world.

Logistics and mobile workforces

Companies with drivers or distributed field teams use NexCon eSIMs to onboard devices quickly via a single generic QR code. Each user activates connectivity themselves. The company manages everything centrally through a shared eSIM pool.

IoT hardware and connected device deployments

Hardware manufacturers and system integrators ship eSIM-ready devices without inserting a removable physical SIM card, then activate connectivity remotely across customers, countries and markets.

Wearables and connected products

For wearables and connected consumer-like devices, onboarding needs to be simple and scalable. NexCon eSIMs let end users connect via QR code or link, while the company retains full control over connectivity in the background.

Skip operational complexity. Start scaling your deployment.

Most IoT deployments hit the same wall because physical SIM logistics, manual provisioning, and fragmented management slow everything down. Talk to us about your setup. We'll help you find the right solution from the start.
