We are constantly evaluating new features for the OSCAR Management Portal. We recently have received requests to include the ability to limit (blacklist) connectivity on certain networks for specific SIM cards. This feature can be helpful to troubleshoot or to ensure access only to specific networks in a particular country. NOTE: This function is only available on accounts with “BITW” type SIM Cards.
This capability can be seen on the SIM Settings page in the “Set Country Restrictions” section. While you could always restrict access in a particular country, this allows you to be more granular by restricting the individual networks. NOTE: to restrict the country completely, choose all networks in the country you want to restrict: You can see in the above example that SIM # 883240000120757 is now being restricted for use on the MTN network in Cyprus, the O2 network in Czech Republic and the Telia Network in Denmark. This function is also available as a bulk operation on the SIM card page.
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.

Wrap-Up:
Here’s the truth: The future isn’t just connected. It’s intelligently connected. IoT SIM cards are what make that intelligence possible—quietly powering everything from tractors to traffic lights. If you’re building anything smart in 2025 and beyond, these SIMs should be in your toolkit.
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.

You can get data from places you could not before. Your devices sip power, they do not gulp it down. This makes a strong base for all your smart plans.
Why Fixed Addresses Are Great for Smart Devices?
Now, let us talk about where things live online. Every Device on a network has an IP address. It is like your home address, but for the internet. Most of the time, these IP addresses change. They are like a new temporary address each time your device connects. This is okay for your phone. But for smart devices, it may not be optimal.
Basically, fixed IP addresses bring order to the internet addresses of your devices. For smart networks, this means easier access, better safety, and simpler management. It gives you a solid base to build on.
When Fixed Addresses Meet Special SIM Cards – It’s a Perfect Match!
Now, here is where things get really good. Think of NB IoT as the reliable way your devices talk to the internet. Think of fixed IP addresses as giving each device its own permanent name and online spot.
Because NB IoT uses so little power, your devices in remote places can stay online for years. Because they have a fixed IP address, you can always find them. You do not have to worry about their address changing when they wake up to send info. This makes checking on things remotely super reliable.
NB IoT sim card gives you a reliable, long-distance connection. Fixed addresses give you the stable, always-there online “location”. Together, they make your smart device network strong, safe, and easy to manage. It is a combination that just makes sense for many businesses.

Combining Multiple Networks with No Steering on a Single SIM Ensures the Greatest Coverage & Unsurpassed Redundancy.
In the rapidly evolving world of the Internet of Things (IoT), reliable connectivity is paramount. Devices ranging from smart meters and asset trackers to autonomous vehicles and industrial sensors require continuous, seamless communication to function effectively. That’s where multi-carrier IoT SIM cards come into play. But what exactly are they, and how do they work? This blog dives into the concept, benefits, and functionality of multi-carrier IoT SIM cards.
Understanding IoT SIM Cards
Before diving into multi-carrier functionality, it’s essential to understand what an IoT SIM card is. Unlike traditional SIM cards used in consumer smartphones, IoT SIM cards are specifically designed for machine-to-machine (M2M) communication. They support a wide range of network technologies (2G, 3G, 4G, LTE-M, NB-IoT, and 5G), are often more durable, and can withstand extreme environmental conditions. These SIMs are typically deployed in devices that need to transmit data over long periods without manual intervention.
What Makes a SIM Card Multi-Carrier?
A multi-carrier IoT SIM card is capable of connecting to more than one mobile network operator (MNO). Unlike a traditional SIM, which is locked to a single carrier, a multi-carrier SIM provides access to multiple networks, either through a single profile with multiple network access agreements or by switching between different profiles stored on the SIM.
This flexibility is crucial for IoT deployments across different geographical regions where a single carrier might not have adequate coverage. A multi-carrier SIM ensures that the IoT device always connects to the best available network, enhancing reliability and uptime.
How Does a Multi-Carrier IoT SIM Work?
There are two primary methods by which multi-carrier IoT SIMs operate:
1. Network Steering (Roaming Agreements)
In this method, the SIM card connects to multiple networks using roaming agreements negotiated by the SIM provider. The card will prioritize certain networks based on availability, signal strength, or cost. The selection process can be dynamic or predefined by the SIM provider.
It is important to note, though, that not all multi-carrier SIM cards are created equal. Many providers, especially “native” SIM cards to a country, use a strategy called “network steering” to control costs. They prioritize certain networks, like their own network, over others because using a particular network costs less than using another available network. This will cause a problem because your device may get “stuck” on a network with a poor connection because it is the “preferred” network. When network steering is employed, you won’t be able to use the next preferred network until the coverage is completely missing from the more preferred network.
2. No Steering
No Steering SIM cards are by far the better choice for any IoT deployment. This type of IoT SIM card will allow the device to make the choice on which network to attach (usually based on RSSI value). You always want to check and make sure the SIM card you are deploying are no steering SIM cards.

We live in a time of great change in how things connect to each other. Your refrigerator can buy food, your thermostat can change on its own, and street lights can illuminate based on how many folks walk by. This is due to the Internet of Things (IoT), a web of connected devices that shape how we live and work. But to make all this work, we need one key thing: a strong connection at all times.
While your phone’s SIM card lets you talk with friends and family, it is not built for what IoT devices need. IoT devices often work far from towns, use less power, and send small bits of data more sporatically. That is where SIM card for IoT help. They provide a different method that shifts how we connect our homes and towns.
What is an IoT SIM Card and How Does It Work?
An IoT SIM card is a type of SIM card made just for machine-to-machine (M2M) communication. Unlike the ones we use, which help folks chat, IoT SIM cards enable devices to talk to each other and send data to a main hub.
Tech-wise, a SIM card for IoT works like a normal SIM card but has key perks. It uses cellular networks to send data, but it is made to be strong and work well, including so-called “permanent roaming”. One major advantage is that it can use many cellular networks worldwide. This means an IoT device can switch networks with ease to stay connected, even if it moves to new locations or if a network goes down.
At its core, an IoT SIM card lets M2M communication happen. This means devices can share data on their own. For one, a sensor in a field can send data on soil moisture to a hub, which then turns on or off water flow. This type of connection is key for many IoT uses.
