Why Your IoT Project Needs a SIM Management Portal (and What to Look For)

Image depicting the concept of an IoT SIM Card management portal

As businesses increasingly deploy connected devices across industries like logistics, smart agriculture, manufacturing, and security, one crucial component stands between success and chaos: the IoT SIM card. While choosing the right SIM card is essential, managing those SIMs efficiently is equally critical. That’s where a SIM management portal becomes indispensable.

In this blog, we’ll explore why an IoT SIM card management platform is a must-have for any large-scale deployment, what features to prioritize, and how platforms like OneSimCard’s OSCAR portal can help streamline operations, reduce costs, and maintain connectivity across global networks.

The Growing Complexity of IoT SIM Card Deployments

An IoT SIM card enables devices to connect to cellular networks for data transmission. Unlike traditional SIM cards, IoT SIMs often require:

Global, multi-network connectivity
Remote provisioning
Lifecycle monitoring
Scalable deployment for hundreds or thousands of devices

Managing all of this manually—or through a basic interface—is inefficient and error-prone. This is especially true as your IoT project grows across borders or industries. That’s where a powerful, but simple-to-use SIM management portal becomes a strategic asset.

What is a SIM Management Portal?

A SIM management portal is a centralized web-based platform that allows businesses to control, monitor, and optimize every IoT SIM card in their network. It acts as the command center for all your IoT connectivity needs, offering visibility and control over SIM activity, usage, billing, and diagnostics.

Why Your IoT Project Needs a SIM Management Portal

1. Full Visibility and Real-Time Monitoring

One of the biggest challenges in managing IoT devices is a lack of visibility. A good SIM management platform offers real-time tracking of data usage, SIM status, location, and more.

With tools like OneSimCard’s OSCAR, businesses can:

Instantly see which SIMs are active or inactive
Monitor data consumption trends
Detect anomalies before they turn into problems

This level of transparency reduces troubleshooting time and enhances operational efficiency.

2. Control at Scale

Managing 10 SIMs manually might be possible. But managing 10,000 SIMs across dozens of countries? You need automation.

A robust IoT SIM card management system lets you:

Activate/deactivate SIMs remotely
Set data limits and alerts
Batch update settings for groups of devices
Schedule automatic SIM suspension if thresholds are exceeded

This kind of centralized control helps reduce overages, prevent fraud, and ensure consistent performance across your device fleet.

3. Cost Optimization

Without visibility, it’s easy to lose track of roaming charges, idle SIMs, and over-provisioned plans. A management portal helps you:

Analyze usage patterns to right-size data plans
Disable or suspend unused SIMs
Avoid “bill shock” with alerts and daily monitoring

Platforms like OneSimCard’s OSCAR even let you generate usage reports by country, device, or time period, empowering better budgeting and vendor negotiations.

4. Security and Fraud Prevention

IoT devices are increasingly targeted for unauthorized usage. A SIM management portal helps protect your infrastructure with:

IMEI lock: restricts a SIM to a specific device
Geo-fencing: restrict usage to approved countries or regions
Alerts for unusual data usage or behavior
Remote deactivation for compromised SIMs

When dealing with critical infrastructure like smart meters or security systems, these features are non-negotiable.

5. Compliance and Audit Readiness

Many industries—including healthcare, finance, and transportation—are subject to data and operational regulations. A SIM management system supports compliance by:

Logging all user actions and SIM activity
Keeping historical data usage records
Providing user role-based access controls

This auditability ensures that your IoT SIM card deployment meets both internal and regulatory standards.

6. Simplified Troubleshooting

Imagine your field technician is trying to fix a device in a remote location. Without a management portal, diagnosing the issue is a guessing game.

With a SIM portal, support teams can:

Check connection logs
Reboot SIM or reset settings remotely
Identify if the issue is network, hardware, or SIM related

This dramatically shortens resolution times and improves device uptime.

What to Look for in an IoT SIM Card Management Portal

Not all portals are created equal. Here’s what to prioritize:

✔️ Real-Time Dashboard

You want a visually intuitive dashboard with charts and indicators that show active/inactive SIMs, top users, alerts, and anomalies in real time.

✔️ Multi-Network Control

If your SIM provider offers multiple network options per country (like OneSimCard’s multi-IMSI IoT SIMs), make sure the portal can show you which networks are being used, and allow manual or automatic switching.

✔️ Remote SIM Management

Look for the ability to activate, suspend, and delete SIMs from the portal—individually or in bulk.

✔️ Usage Alerts and Reports

Set up alerts for data limits, roaming usage, or inactivity. Schedule reports by day, week, or month to help forecast usage and budget effectively.

✔️ Secure Access Controls

A good portal will allow for multi-user access with role-based permissions, and strong authentication options to secure sensitive data.

✔️ API Access

For advanced users, API access allows you to integrate SIM management functions directly into your own software, CRM, or operations dashboard.

Why OneSimCard’s OSCAR Portal Stands Out

If you’re deploying IoT SIM cards, OneSimCard’s OSCAR portal offers one of the most powerful and intuitive management platforms available.

Here’s what it includes:

Real-time SIM status and usage monitoring
Activation/deactivation from a single dashboard
Custom usage alerts to prevent overages
Multi-network redundancy across 200+ countries and territories
Batch actions for large deployments
Device locking, geo-fencing, and IP whitelisting
API integration for enterprise-grade control
No extra charge for full portal access

Whether you’re managing a few dozen SIMs or a global deployment of thousands, OSCAR simplifies your operations while keeping you in control.

Final Thoughts

As your IoT ecosystem grows, the complexity of managing connectivity grows with it. Without a powerful SIM management portal, even the best IoT SIM card can become a liability rather than an asset.

From visibility and cost control to compliance and uptime, a robust portal is essential for ensuring your IoT project delivers long-term value.

So when evaluating IoT connectivity partners, don’t just ask about data rates and coverage. Ask about the portal. Because in the world of connected devices, control is everything—and the right SIM management portal is your command center.

Stay Connected Anywhere: Smart IoT SIM Cards for Global Control

A few years ago, we had a client in the agricultural tech space struggling to keep their soil sensors online in remote areas of sub-Saharan Africa. Their problem? Local SIM cards that couldn’t hold a connection for more than a few hours. Fast forward to today, they’re running the same system using OneSimCard IoT SIM cards with multi-network support, and no downtime. That’s the real-world difference smart connectivity can make.

And it’s not just AgTech. Whether it’s a logistics fleet avoiding highway closures in real-time, or medical devices monitoring patients remotely, IoT SIM cards are no longer optional but they’re mission-critical.

What Exactly Is an IoT SIM Card?

Think of an IoT SIM card as the evolved version of the SIM in your mobile device. But instead of just making calls or sending texts, it enables machines—vehicles, sensors, wearables to send and receive data globally, 24/7. These cards are:

Engineered for scale – built to support thousands, even millions, of devices.
Durable – resistant to dust, vibration, and extreme temperatures.
Flexible – remotely programmable and manageable through cloud platforms.

Unlike consumer SIMs, these are tailored for machine-to-machine (M2M) communication, meaning they’re more about sending telemetry than talking to grandma.

Why the Surge in Popularity?

In 2024, the IoT SIM card market hit $8.15 billion—and it’s not slowing down. By 2032, forecasts suggest over $21 billion in value. Why? Here are a few reasons, straight from our clients’ use cases:

Manufacturing: Assembly lines get smarter with condition-monitoring devices that help avoid costly breakdowns.
Healthcare: Telemedicine kits and remote monitors connect rural patients to urban hospitals.
Energy: Smart grids and utility meters ensure efficient power distribution and load balancing.
Logistics: From warehouse sensors to real-time GPS on trucks, everything talks to everything.

The Control Center: OneSimCard IoT Management Portal (OSCAR)

Now here’s something, centralized SIM control. The OneSimCard Account Resource (OSCAR) Portal isn’t just a dashboard. It’s a command center. You can:

Activate or block cards instantly
Track real-time usage across thousands of devices
Organize SIMs by project, region, or team
Set automatic usage rules and alerts
Utilize our simple API’s to link OSCAR to your portal

This kind of insight isn’t nice-to-have; it’s necessary. Whether you’re managing tens, hundreds or thousands field devices, you need to know which one’s acting up before your operations take a hit.

Types of IoT SIM Cards: What’s the Difference?

Not all SIMs are the same. IoT SIMs are built to work in remote areas, with low power, and for long spans of time. Here’s how they stand out:

Global Reach – They work in many countries and use more than one network.
Durable – They can take heat, cold, dust, and more.
Low Power Draw – Great for tools that run on a small charge.
Remote Tweak – You can change them from far off and no need to swap.

Type	What It Means
Standard 3-in-1	Removable, like in your phone, but used in industrial-grade hardware.
MFF2 – sometimes called eSIM	Embedded in the device—no physical slot, just software-controlled flexibility.
iSIM	Integrated directly into the chipset. The future of ultra-compact, secure design.

We recommend MFF2 SIMs for most industrial applications because they balance durability and remote reconfigurability perfectly. iSIMs are still emerging but exciting.

Connectivity Without Borders

OneSimCard IoT SIMs use multi-network technology to automatically switch to the strongest signal, no matter where you are. No single-network dependency means

Less dead zones
No need to physically swap SIMs in the field

Let’s put this into context. IoT SIM cards aren’t just for tech geeks, they solve daily operational challenges across industries:

AgTech: Soil moisture too low? The irrigation system adjusts automatically.
Fleet Tracking: Vehicles ping their location every “X” seconds, even across borders.
Smart Cities: Waste bins send alerts when full, street lights adjust based on activity.
Remote Healthcare: Wearables transmit vital signs to doctors miles away.
Utilities: Pipeline sensors detect leaks instantly, reducing environmental and financial damage.

But What About Security?

We get this question all the time—and rightly so. More connected devices = more risk. A 2023 study showed vulnerabilities in some telecom APIs that manage IoT SIMs.

Here’s what works:

Private APNs: Isolate your devices from public networks.
VPN Tunnels: Encrypt your data end-to-end.
IMEI Locking: Pair each SIM to one specific device—no unauthorized swaps.

OneSimCard offers all of these. If you’re serious about security (and you should be), don’t settle for basic.

Data Plans Built for Reality

Not every IoT device guzzles data. Some send kilobytes a week. Others stream 24/7 video. OneSimCard offers:

Pay-as-you-go plans—ideal for low-usage devices
Shared data pools—perfect for fleets and multi-device deployments
Custom enterprise packages—for those big, mission-critical rollouts

You can scale up or down anytime. No awkward lock-ins or surprise charges.

A Simple Setting Can Save You Thousands of Dollars: Controlling Your IoT SIM Card Cost

Device with IoT SIM card spending too much money.

IoT deployments can be complex and a lot of planning is important to make certain everything goes as expected. One of the simplest things often gets overlooked and this simple missed step can be a very costly oversight.

Let’s face it, cost matters when it comes to every component in IoT solution development. Margins can be super thin, so any surprise can be very impactful. You need to protect yourself from anything that will blow up your costs. IoT SIM card connectivity plans can be very inexpensive, if your provider gives you the proper controls and you use them properly.

One of the very basic functions any reputable connectivity provider will include in their IoT SIM management portal is the ability to limit how much data your SIM cards can consume. Going over your included plan usually costs much more than the effective per MB cost included with the plan. If your connectivity provider doesn’t include this capability, run, don’t walk, away!

It’s not enough to just have the function to limit the amount of data a SIM can use, you actually need to set this in the management portal. The amount of data you allow the IoT SIM card to consume depends on the type of plan you have. See our blog on choosing the right type of plan here.

For example, if you are using a pooled data plan, your devices usually consume a known, consistent amount of data with only a small amount of variance. in this case, to take advantage of the pooling/sharing data capability it is a good rule of thumb to set the data limit at 20% – 50% more than the pool size (large data plans should be set much lower though because IoT devices like remote cameras usually have plans of 1-5GB, or more, and overage can add up fast!).

Pay-As-You-Go (PAYG) plans are set differently. With these plans, the SIMs usually vary in the amount of data they use. You should set these limits to the amount you want to pay each month. For example, if your budget for connectivity is $5.00 per month and your data cost is $0.01/MB, then set the limit to 500MB.

OneSimCard IoT offers a feature rich IoT SIM card management portal that includes the ability to set data limits on either type of plan, pooled and PAYG. We always encourage our customers to set data limits on their SIM cards because we understand, through our over 30 years of connecting clients, every dollar matters when going to market with an IoT solution.

Understanding IoT SIM Card ICCIDs: What They Are and How They Work

Introduction

The Internet of Things (IoT) has revolutionized industries by enabling seamless communication between devices. At the core of this connectivity are SIM (Subscriber Identity Module) cards, which allow IoT devices to connect to cellular networks. Each IoT SIM card comes with a unique ICCID (Integrated Circuit Card Identifier)—a critical component for managing and identifying SIM cards across global networks.

In this blog, we’ll explore what an ICCID is, how it is created, and what the numbers in an ICCID mean. Understanding ICCIDs is crucial for businesses deploying IoT solutions, as they help in managing large fleets of connected devices.

What is an IoT SIM Card ICCID?

An ICCID (Integrated Circuit Card Identifier) is a unique number assigned to every SIM card, including those used in IoT devices. This identifier plays a vital role in distinguishing SIM cards across different networks and regions. Unlike the IMSI (International Mobile Subscriber Identity), which identifies the subscriber, the ICCID is linked to the physical SIM card itself.

The ICCID is embedded in the SIM card during manufacturing and is stored in its memory. It is also printed on the SIM card body so that network operators and users can easily reference it. The ICCID follows a standardized format defined by the International Telecommunication Union (ITU-T) in the E.118 recommendation.

IoT SIM cards, which are often used in smart meters, connected vehicles, industrial sensors, and other machine-to-machine (M2M) applications, rely on ICCIDs for inventory management, provisioning, and network authentication.

How are ICCIDs Created?

ICCID numbers are generated following a specific international standard to ensure uniqueness and consistency across the global telecom ecosystem. The structure of an ICCID adheres to the ISO/IEC 7812 numbering system, which is also used for bank card numbers.

Here’s the process of how ICCIDs are created:

Assignment of the Issuer Identification Number (IIN):
- The first few digits of the ICCID are assigned to the telecom provider or SIM card issuer.
- This ensures that no two operators generate conflicting ICCIDs.
Encoding of the Unique Account Number:
- The SIM card manufacturer assigns a unique serial number to each SIM card.
- This number helps in tracking and differentiating SIMs produced in the same batch.
Incorporation of a Checksum Digit:
- To ensure the validity of the ICCID, a Luhn algorithm is applied to generate the final check digit.
- This helps in detecting errors in the ICCID when it is entered manually or scanned.

Once generated, the ICCID is permanently stored on the SIM card and cannot be changed.

Breaking Down the ICCID Number

An ICCID is typically 19 to 20 digits long and follows a structured format:

Example ICCID:
89 12 3456 7890 123456 7

Each part of the ICCID has a specific meaning:

Industry Identifier (2 digits) – “89”
- The first two digits always start with “89”, which indicates that the card is used for telecommunications.
- This is a globally standardized prefix.
Country Code (1–3 digits) – “12”
- The next set of numbers represents the country code, assigned by the International Telecommunication Union (ITU).
- It helps identify the country where the SIM card was issued.
Issuer Identification Number (IIN) – “3456”
- This segment identifies the mobile network operator (MNO) or SIM card issuer.
- Different telecom providers have unique IINs.
Unique SIM Card Serial Number – “7890 123456”
- This is a manufacturer-assigned unique number for each SIM card.
- It ensures that no two SIM cards have the same ICCID.
Checksum Digit – “7”
- The last digit is a mathematically calculated check digit using the Luhn algorithm.
- This helps prevent errors when entering the ICCID manually.

Why are ICCIDs Important for IoT?

ICCID numbers play a crucial role in IoT deployments. Here’s why they matter:

1. Device Authentication & Security

Networks use ICCIDs to authenticate and register IoT SIM cards, ensuring that only authorized devices connect to the network.

2. Remote SIM Management

With large-scale IoT deployments, companies use ICCIDs to track and manage SIMs remotely through SIM management platforms.

3. Network Provisioning & Roaming

ICCIDs help in identifying SIMs that are configured for specific network access, including multi-network and global roaming IoT SIMs.

4. Troubleshooting & Customer Support

If an IoT device experiences connectivity issues, network operators can use the ICCID to diagnose and resolve problems.

5. Compliance & Inventory Tracking

Businesses with thousands or millions of IoT SIMs use ICCIDs to ensure compliance with telecom regulations and keep accurate inventory records.

ICCID vs. IMSI vs. IMEI: What’s the Difference?

While ICCID, IMSI, and IMEI are all used in telecom networks, they serve different purposes:

Identifier	Stands for	Purpose	Assigned to	Can Change?
ICCID	Integrated Circuit Card Identifier	Identifies the physical SIM card	SIM Card	No
IMSI	International Mobile Subscriber Identity	Identifies the mobile subscriber	Linked to a SIM profile	Yes (with eSIMs)
IMEI	International Mobile Equipment Identity	Identifies the device hardware	Device (e.g., phone, IoT module)	No

For IoT applications, ICCID is crucial for managing SIM inventory, while IMSI is essential for network authentication, and IMEI helps in tracking devices.

Conclusion

ICCID numbers are an essential part of IoT SIM cards, enabling seamless connectivity and efficient SIM management. By understanding their structure, creation process, and significance, businesses deploying IoT solutions can better manage their SIM inventories and ensure secure, reliable network connections.

As IoT adoption continues to grow, ICCIDs will remain a key component in identifying and authenticating millions of connected devices worldwide. Whether you’re managing a fleet of smart meters, connected vehicles, or industrial sensors, keeping track of ICCIDs ensures a smooth and secure IoT deployment.

We are excited to introduce you to our new IoT SIM card type: the BITW. We have been working feverishly over the last 18 months to find new connectivity partners and integrate the selected partners into our cloud-based portal. When selecting new partners, we took many of the suggestions/requests our customers have made like getting access to NB-IoT technology. You may have heard this was coming, but the time has come to officially announce this amazing service.

OneSimCard IoT BITW SIM Card features:

1) Multi-IMSI, Multi-Carrier, No Steering SIM Cards offering build-in redundancy and reliability virtually anywhere in the world.

2) Much Lower Costs in many countries and in many instances (depending on the expected data consumption) the cost of data is more than 1/2 of our “old” SIM cards. Rates start at less than $0.01/MB;

3) More Form Factors. OneSimCard IoT BITW SIM cards are available in 2FF, 3FF, 4FF, MFF2, and eSIM

4) Fully Functional including Private Static IP addresses, IPSec VPN, Private APN, Alarms, API’s (coming by the end of July), Portal SMS & much more;

5) New Features including the ability to view the IMEI of the device in which the SIM is installed, and an alarm available to notify you if the IMEI is changed (IMEI lock is also still available);

6) More Network Protocols Including NB-IoT. The new SIMs support 2G, 3G, 4G (Full LTE, Cat M, Cat M1, & NB-IoT) & 5G.

7) Flexible Plan Types. Just like our “old” SIM cards, OneSimCard IoT BITW SIMs are available for both Pay-As-You-Go (PAYG) and Pooled data plans. The PAYG plans are more flexible and much lower per MB rates than our “old” SIM cards. The Pooled plans are still customized to your needs. The possibilities are infinite!;

eSIMs or Removable SIMs for IoT, Which Is Best?

Image of different IoT SIM card form factors and the dates they were released including eSIM — Plastic SIMs and eSIM (MFF2)

Introduction

Clients often ask “Which should I use, traditional plastic SIMs, or embedded SIMs (eSIMs) for my IoT solution?” Our go-to answer is always, “It depends.” We answer this way because it really does depend on many factors.

In this article we explore the pros and cons of both eSIMs physical SIMs for IoT projects. Not all pros and cons will have equal weight for each solution developer, but we think this is a good primer on the differences of each type of IoT SIM card.

First, let’s quickly define what we are talking about. We wrote an article several years ago that spoke to the evolution of the IoT SIM card specifically relating to the evolution of the technology behind SIM cards. We talked about eUICC as an emerging tech, and we called this an “eSIM.” For the purposes of this article, we are calling the embedded SIM (MFF2 form factor) an eSIM. Physical SIM cards are typically 2FF, 3FF, or 4FF form factors, but can also be enabled with eUICC tech, making them also “eSIMs.” “eSIM” refer to either a SIM with eUICC technology, or an embedded SIM, but these are very different things.

Embedded SIM (eSIM):

eSIM Pros:

Remote Provisioning: eSIMs are provisioned remotely and programmed with the necessary network credentials using bootstrap profiles. This eliminates the need for physical access to the device, and is particularly useful for IoT devices in remote or hard-to-reach locations.
Scalability: eSIMs make it easier to scale your IoT deployment because you can provision and manage a large number of devices without physically swapping SIM cards.
Reduced Physical Footprint: eSIMs are integrated into the device’s hardware, saving space and allowing for more compact IoT device designs.
Improved Security: eSIMs often offer enhanced security features, such as better resistance to physical tampering and improved authentication protocols.
Flexibility: eSIMs can switch between different carrier profiles, providing flexibility and cost optimization as you can select the best network for a given location or situation. However, this requires the cooperation of both carriers which is not always a given. Many carriers will not allow these profile change-overs.

eSIM Cons:

Initial Cost: Implementing eSIM technology may require upfront investments in hardware and infrastructure for remote provisioning and management. Even the MFF2 SIM is more costly than traditional plastic SIMs.
Compatibility: Not all IoT devices are eSIM-ready, so retrofitting existing devices with eSIM capabilities can be challenging and costly.
Dependency on Manufacturers: Device manufacturers must support eSIM technology for it to be effective, and not all manufacturers do, limiting device options.

Traditional Physical SIM Cards:

Physical SIM Pros:

Widespread Compatibility: Traditional SIM cards are widely supported by most IoT devices and have been the standard for many years.
Low Initial Cost: The cost of traditional SIM cards and card readers is generally lower than implementing eSIM technology.
Interchangeability: Physical SIM cards can be easily swapped between devices, which can be useful in some situations.

Physical SIM Cons:

Physical Access Required: Changing SIM cards typically requires physical access to the device, which can be impractical for remote or deployed IoT devices.
Scalability Challenges: Managing a large number of physical SIM cards can be cumbersome, leading to logistical challenges as your IoT deployment scales.
Security Concerns: Traditional SIM cards are more susceptible to physical tampering and unauthorized removal, potentially compromising security.
Limited Network Flexibility: Switching between carriers or network profiles is more difficult with physical SIM cards, leading to potential coverage and cost inefficiencies.

The choice between eSIM technology and traditional physical SIM cards in IoT applications depends on your specific use case and requirements. eSIMs offer advantages in terms of remote management, scalability, and flexibility. Traditional SIM cards are more widely compatible and have lower initial costs. It’s essential to evaluate your project’s needs, device compatibility, and long-term scalability when making this decision.
