Is your organization exploring different ways to connect devices, systems, and people with minimal hassles? One way is to explore the services and solutions enabled by the Internet of Things (IoT). And why not!

The global pool of connected IoT devices reached 16.6 billion by the end of 2023, a 15% jump from the previous year. This number is expected to rise to 18.8 billion by the end of 2024.

Many industry analysts expect continued growth for IoT eSIM applications because of easier scalability and remote provisioning. A global eSIM connectivity strategy lets you handle coverage changes and adjust data plans from a central hub. That approach supports real-time decisions and helps avoid high roaming costs.  

Industries like logistics, oil and gas, technology, and transportation often face operational challenges when managing connectivity across multiple regions and carriers. Embedded SIM (eSIM) technology helps streamline this by removing the need for manual SIM swaps and enabling remote carrier management.

With IoT eSIM applications, you get a practical solution for your business. You won’t have to juggle physical SIM cards since each device uses an embedded SIM that updates carrier profiles through software. 

This approach helps cut administrative hurdles and even opens up global coverage. Let’s find out why it powers business growth and how Spenza’s solutions fit your large-scale deployment goals.

How eSIM Fits in the IoT Environment

eSIM is an abbreviation of embedded SIM. It’s a chip that remains inside a device and accepts over-the-air updates for network changes. Such an arrangement saves businesses from managing countless physical SIM cards through different mobile network operators (MNOs).

Remote provisioning is valuable if your business requires large deployments across multiple geographies. You can swap carrier profiles or tweak data plans directly, which helps a single site or an entire operation function without downtime. Some analysts offer eSIM growth stats that show a steady climb in global shipments. The global eSIM market is projected to grow at a CAGR of 7.9% from 2023 to 2030.

eSIM in IoT Deployment

As IoT deployments scale, businesses often find themselves managing thousands of devices across multiple countries, each with varying network conditions, regulations, and operator agreements. In such cases, eSIM alone isn’t enough. This is where connectivity aggregation platforms become essential.

They allow enterprises to manage connectivity from multiple carriers centrally, optimize data plans, and automate provisioning without negotiating contracts separately for each market.

How Spenza Can Enable eSIM Usage – A Real World Example

Spenza offers this exact capability by consolidating multi-operator management into a single interface. From procurement to monitoring and spend analysis, everything flows through one unified dashboard, eliminating fragmentation and manual effort.

Take logistics as a real-world example: a fleet management company might operate thousands of connected vehicles moving between the U.S., Canada, and Mexico. With traditional SIMs, switching networks across borders means physical swaps or roaming costs. 

But with an eSIM powered by a platform like Spenza, those devices can switch to the optimal carrier in each region, based on signal strength, cost, or usage thresholds, without downtime or manual intervention.

These improvements aren’t just operational perks. 

Faster carrier switching and centralized oversight also mean faster onboarding for new device rollouts, better performance analytics, and more stable service for your entire IoT ecosystem. 

For your business, that translates to lower overheads, reduced downtime, and the ability to scale deployments with confidence.

Key Benefits of eSIM for Enterprises

Several businesses are already seeing the benefits of using eSIMs. Below are some of the major advantages you can enjoy.

1. Reduced Downtime
   Network or plan changes happen through software, which prevents service interruptions and keeps devices active.
2. Optimized Costs
   You get an option to choose different carriers in various regions, which helps manage budgets.
3. Simplified Operations
   One embedded SIM for each device eliminates confusion and manual swaps when requirements shift.

Major Industry Applications of IoT eSIM

Every industry has its connectivity challenges. Some struggle with coverage across vast regions, while others worry about stable service in tough environments. So, your decision to adopt this technology shows greater flexibility, faster setup, and smoother scalability. Each sector gains a unique advantage. Let’s find out in detail.

1. Logistics & Transportation

Fleets often drive in and out of different states or countries, which complicates data usage and roaming. An eSIM setup helps trucks or delivery vans switch carriers, avoiding coverage gaps.

Real-Time Telematics

Data on vehicle health, engine temperature, and location flows into central management systems through eSIM, which allows scheduling maintenance, improving driver routes, and reducing unexpected breakdowns. 

2. Oil & Gas

Rugged sites pose extra challenges. One spot might have strong coverage from Carrier A, while Carrier B works better halfway down the pipeline. However, you can have an eSIM that provides gear operators a way to keep pumps or sensors online.

Remote Asset Monitoring

Oil and gas businesses need real-time visibility into remote assets like wellheads, pipelines, pumps, and compressors for safety, uptime, and regulatory compliance. Their sites may be located in offshore rigs, deserts, or other isolated areas. 

So, managing connectivity for these remote assets at scale requires IoT eSIM to provision, configure, and activate thousands of remote monitoring devices without physical access. This is particularly valuable when rolling out or updating equipment across multiple sites or drilling zones. 

IOT eSIM-enabled devices transmit critical telemetry data such as:

• Pressure and flow rates across pipelines
• Temperature and vibration data from rotating equipment
• Tank level and leak detection alerts
• Real-time health status of remote field units (RTUs)

Compliance and Safety Measures

Minimal downtime contributes to faster alerts and immediate responses to potential hazards. Crew members and managers see accurate readings, so site inspections become more proactive.

3. Tech & Manufacturing

Some factories load up on robotic arms that need constant connectivity. Shutting them down to swap SIM cards is not appealing, and that’s why you need eSIM to trim downtime and keep production lines rolling.

Automated Plants

Robotics, industrial sensors, and 3D printers need uninterrupted connectivity. Manufacturing eSIM setups deliver reliable links that do not require any physical replacements if a carrier change becomes necessary.

Scaling or Relocating

Production lines sometimes expand to new plants or relocate equipment. A single eSIM approach avoids the tedious process of procuring and installing fresh SIM cards.

4. Other High-Potential Sectors

1. Healthcare eSIM
   Medical devices designed for patient monitoring or hospital logistics must maintain strong signals, which are necessary for continuous data flow.
2. Agriculture eSIM
   Farm sensors track soil moisture, weather conditions, and pest activity with embedded SIMs, eliminating the hassle of frequent replacements in rural zones.
3. Connected Urban Infrastructure
   Usage in smart city eSIM plans supports metering, lighting controls, and public safety systems.

Let’s take a few example use cases across different industries:
