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.

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.

Internet of Things (IoT) is changing how companies operate and how we live. From smart devices in farms to health gear, IoT is now in all industries. But for IoT to work well, a smooth is a must. A break in communication can lead to lost data, interruption in work, and even costly failures. That’s where IoT SIM cards help, as they let unmanned machines talk to each other and main hubs.
This blog will show you how to set up and run SIM cards IoT for a smooth . We will go through each step, from setup to fixing faults, so you get the most out of your connected devices.
1. Plan for IoT SIM Card Setup
Before you start, you must plan well to make sure everything runs smoothly.
Check Connection Needs (Local vs. Worldwide Reach): First, know your communication needs. Will your devices work in one area, or do they need a worldwide reach? If you work in one spot, limited coverage to save costs will do. But if you need a SIM for international use, a global IoT SIM is key, even with higher costs.
Pick the Right IoT SIM Card for the Device and Use: Not all IoT SIM cards are the same. Think of what your devices need. Some need low power, while others need high speed. Make sure the SIM card you pick meets these needs.
Know Network Fit and Data Use: Check if the IoT SIM card works with the cell networks in your area. Also, understand how much data you will use. If you choose too much, you may waste money. If you pick too little, your devices may stop working. Look for a provider like OneSimCard IoT that can customize data plans to your needs, rather than trying to force you into to the “cookie-cutter” plans the provider offers.
2. Install and Activate the SIM Card
Once you pick the right IoT SIM card, it’s time to set it up.
Step-by-Step Guide on How to Install and Set Up an IoT SIM: Put the SIM card IoT in the device as per the manufacturer’s guide. Make sure it fits well to mitigate connection issues.
How to Activate an IoT SIM Card with OneSimCard: OneSimCard makes this easy with its online portal called OSCAR. Follow the steps given to activate your SIM card and set up your account.
Set APN (Access Point Name): CorrectAPN settings are critical for your device connection to the internet. Use the right APN settings from your network provider. Wrong APN settings will stop your device from establishing a data session.
3. Run IoT SIM Cards for Large Use
To run many IoT devices, you need a capable management portal.
Management portal for Remote Control: An IoT management portal lets you check your SIM cards remotely. You can track data use and manage the connection of each device. This makes it easy to run a large deployment.
Check Data Use and Switch Nets for Best Connection: Watch data use to spot odd use and cut waste. Use net switch plans to keep a smooth connection and cut costs.
Set Alerts for Odd Use and Fix Connection Issues: Set alerts for suspicious data use or connection issues. This way, you can fix problems fast and keep all devices connected.
4. Best Ways to Keep IoT SIM Cards Secure
Security is key in IoT.
Use Lock Codes and VPN for Safe Data Flow: Secure your data so no one can see it. Use a VPN to help ensure data integrity.
Prevent Unauthorized Use with Secure Login: Use strong logins to secure your IoT devices.
5. Fix Common IoT SIM Issues
Even with a good plan and a solid provider, you may face connection issues.
Fix Connection Issues and APN Errors: Check APN settings and make sure the device is in the network coverage area. If the issue remains, restart the device and/or call the provider.
Solve SIM Card Read Failures in IoT Devices: If the device does not see the SIM card, take it out and put it back in. If the issue continues, the SIM card may be damaged or defective and you should try to replace it.
Steps to Fix Network Failures: If the network fails, switch to a new network. Having a no-steering, multi-carrier provider is critical for this

As Agricultural Technology grows (pun intended) in popularity around the world, connecting all of these “things” is increasingly more difficult. International implementations face many obstacles. We focus on the issues with IoT SIM card use in worldwide operations. Some of the same complications occur in single country use as well. Streamlining these deployments saves time, money & headaches. This article focuses on one such case. We will discuss a soil moisture sensor company struggling with their multi-national deployments. We will cover their solution, their initial problem, the steps they took to remedy the situation, and the solution they chose.
The Customer’s Description
As a Start-Up, this company needed to grow fast and were sending their moisture sensors all over the world, and they had pilots currently running in 27 different countries. Their solution includes a mesh network of wireless sensors spread over the fields of a grower and all of the data aggregated in a gateway device that sends all of the data back to a server for analysis and reporting on their UI. The gateway device is a standard rugged router. It uses a 3FF global IoT SIM card powering the connection to the back end through cellular networks. The gateway required bi-directional proactive communication because they needed to reach the gateway from time to time on demand. Their sensors test the soil every 3 hours. The total amount of data per gateway averages 72MB per month.
The Problem
They struggled with how they would put together a solution for all of these disparate countries, though. It takes time and resources to find an IoT SIM card provider in each country. Using these various providers further complicates matters because they had to manage multiple SIM management portals, multiple APNs, SKUs for each IoT SIM card provider, and several languages to deal with (English, French, Spanish, Portuguese, Russian, Chinese, and German to name a few).
All of this takes time and resources. As a small company, their time really does mean money, because navigating all of the vendors, and programming their routers based on where the devices were being sent took time away from marketing and selling their solution. They estimated it took 47% of their time finding local cellular providers. Also setting up the new vendors’ APN’s and SKUs into their workflow, learning a new portal for SIM card management, etc., etc. That is all time when they could be building a strong sales funnel, meeting with new prospects, working on marketing efforts, and so forth. They estimated if they could focus 47% more time on these tasks, their annual revenue would grow over $1M.
What They Tried
Over the last 6 months they tried to standardize their connectivity providers to a smaller number. They thought this would solve the issues. What they discovered was that it did help, but the benefits were not sufficient. The CTO and COO still had to think about how devices needed to be configured for each country. They also had to manage multiple platforms which takes time to learn and implement different portals and the API’s each portal used (if they supported API’s). They also had different IP ranges to deal with, where a single IP range would be easier to manage because they could used a single VPN with a single IP range.
The OneSimCard IoT Sim Card Solution
We came to the table with our ears open. We heard their problems and developed a solution tailored to their particular needs. What we came up with was a single, Multi-IMSI, eUICC enabled Global IoT SIM card. Our IoT SIM card is used virtually anywhere in the world with a single APN. OneSimCard IoT covers 200+ countries and territories. A single APN means they are able to set-up all of their devices the same, regardless of the device’s destination.
We also provided the client a single private static IP range large enough to support all of their IoT SIM card deployments for the foreseeable future. We recommended an OpenVPN solution for their bidirectional proactive communication to their cellular gateways. Because it only allows one concurrent user, OpenVPN is a low cost alternative to our IPSec VPN solution. It provides the communication this client needed, though.
The client also benefited from the use of our OSCAR SIM management Portal. OSCAR is built in-house from the ground up. When a customer wants to make a change, we make that change quickly. This flexibility helps our clients by catering to their specific requirements without over-complicating the experience. OneSimCard IoT’s portal is cloud based and has mobile apps available on Google Play as well as Apple’s App Store. We also provide a full set of API’s to our Portal. This allowed the client to tie their portal to ours with only one set of API’s.
The Result
The benefit was immediate. Streamlining to a single provider gave the client back their valuable time. They now can concentrate more time and resources on revenue producing activities. In the first month since the change to OneSimCard IoT, they were able to implement 20% more solutions. They also were able to add 25% more new opportunities into their sales funnel. If 5% of these prospects close, this adds $1.5M in annual revenue.

New SIM Search Filter Added for SIMs with IMEI Lock
An M2M Sim card client requested to search for all M2M SIM cards with the IMEI lock enabled. With this update, M2M SIM cards with the IMEI lock engaged are now quickly identified. Many devices can be changed because the M2M SIM cards with the lock can be unlocked. This was particularity important for this client moving IoT SIMs from older 3G devices to their new 4G devices. Once the SIMs that had the lock were identified there is now a new bulk operation to remove the IMEI lock.
M2M SIM card filter list
New Bulk Operation Added to Remove IMEI Lock
In concert with the above IoT Sim card filter, we added a new bulk operation to remove IMEI locks on many SIMs at once. This additional functionality makes the process of SIM card IMEI locks much faster because the administrator no longer has to go in the the SIM settings for each SIM to remove the lock. If you have thousands of M2M SIM cards, this was very time consuming. An administrator can now perform this function to many M2M SIM cards at once.

We continue to listen to our IoT clients and their requests for improvements to our OSCAR IoT SIM Card Management Portal. There is now an API command for both Pooled and PAYG accounts, allowing a SIM reset. A SIM card reset takes the IoT SIM card off the network and allows it to re-register. Before now, this tool was only available on the Portal in the Service tab. There are many customers who prefer to manage most of the tools for their global IoT SIM Cards off the OSCAR management portal. This new API will help with initial troubleshooting of the IoT SIM.
New SIM Card Type Being Launched
For customers using the TCNS IoT SIM card type, you will start to see orders being filled with a new IoT SIM card named “TCNS – E”. This SIM will give you the same outstanding service you are used to, & will add some network operators. The most notable change is in Canada where we are adding Telus and Bell. Now all three major networks in Canada are available. There are also many other countries coming to this Multi-IMSI TCSN-E IoT SIM card. This is great news as we continue to grow our global IoT SIM card footprint and build more network redundancy!
If you have any questions about these enhancements to our IoT SIM card management portal, OSCAR, or any other suggestions or comments, please reach out to feedback@onesimcard.com.
New API Command Available for Updating User Name and Device Fields
We added a new API command for both Pooled and PAYG accounts This command will allow you to update the User Name and Device fields for your IoT SIM Cards in the OSCAR portal. This is especially useful when you are using your own portal to activate IoT SIMs & include the User Name (nickname). The User Name & Device Type are now populated to our OSCAR portal automatically through API. Before now, these fields could only be updated on the Portal in separate tabs. Automating this process is a great time-saver!
New Feature in the OSCAR Portal Allows for Updating/Making Changes to up to 200 SIMs at a Time
Before this update, the maximum number of SIMs that can be displayed on the SIM card page was 100. You could select up to all 100 and perform a bulk operation on these SIMs. Also, these SIMs had to be in certain logical order (sorted by SIM #, ICCID, Status, etc.). If you wanted to work on SIM cards that were not consecutive in this logical order, or only some of those SIMs but not all, you needed to select (or deselect) only those which you want to work on. Last month, we added functionality to upload a CSV file into the portal with the SIM card numbers on which you want to work. You will see this file upload option at the top of the SIM card page. This upload tool allows you to load a CSV file with up to 200 SIM cards at a time. Now you can work on more SIMs at once, and choose the SIMs you on which you want to work based on the file you uploaded (maybe it was a report you ran, etc.).
If you have any questions on these new functions or any other questions on the OSCAR IoT SIM card management portal, please reach out to our IoT experts at Sales@OneSimCard.com.
