An IoT SIM is Not a Smart Phone SIM

Smartphone SIM cards provide connectivity, but does not come with additional functionality offered by IoT connectivity providers. IoT SIM cards are specifically designed for smart devices. It allows devices to connect and communicate with each other. This make it easier to automate processes, increasing operational efficiency and accelerating scalability, while maintaining gold standards of security.

Coverage 

Think of your smartphone SIM. There is likely a contract outlining terms that bind it to a single network and operator. Under this arrangement, you pay a monthly bill for defined services such as data usage. When travelling, you often incur additional roaming rates. These rates depend on the roaming agreements that your provider has with foreign networks.  

Imagine the business implications of such an agreement for your IoT devices which extends to: 

• Sourcing and managing different connectivity providers on a per-country basis and having to adhere to varying contracts and costs 
• Terms determined by network operators, making altering of contractual terms a complicated process
• Unfavorable roaming charges when devices are deployed in different regions
• Increase manufacturing and inventory costs to manufacture and distribute devices globally

Unlike inflexible, costly smartphone SIMs, IoT SIMs open up possibilities to enable your success.

• A single IoT SIM has access to over 500 local networks across 200 countries. This eliminates hassle associated with managing multiple contracts and SIMs
• IoT SIMs seamlessly switch between networks, prioritizing the best available one 
• Accommodate your specific business needs with pay-as-you-use pricing

Security 

Smartphone SIMs have dynamic private IP addresses (IPv4) assigned by the network when they connect. These can even change over time. Most IoT SIM service providers use static IP addresses in combination with a virtual private network (VPN) for added security.  

Static IP addresses remain the same until a device is decommissioned, or the network architecture changes. This allows service personal to remotely login to the device and execute commands, analyse log files or change configurations. 

But the reality is that static IPs are more vulnerable. With a static IP address, bad actors know exactly where your server or device is by scanning the network, making it easier to attack it. 

ZARIOT IoT SIMs give you a way to securely manage your IoT devices, without the need for static IP address, IP ports or VPN and firewalling equipment. In partnership with Atsign, we remove the need for fixed IP addressing and open ports for connectivity by using just a single device identifier and the unique functionality of the @ application.  

Control 

Regular SIMs for consumer devices largely omit user interfaces and management platforms as there exists little need amongst the average user base. This means you are missing out on valuable insights into device functionality and monitor for abnormalities. For example, to reduce costs you may want to specify parameters for data usage and set an alarm to automatically disable a rogue device that exceeds usage limits, lowing data costs.  

Real-time, 24/7 analytics on connectivity, data volume, usage for each device, and the ability to manage and customize these options are additional perks. A management platform is also crucial to maintain reliability, especially if devices are deployed where accessibility for service personnel is limited. You can also easily deploy, pause, resume or cancel your IoT SIM card at any time.

Bonus features 

Additionally, ZARIOT SIMs also offer the following that regular smartphone SIMs do not: 

• End-to-end data encryption using the SIM as the root of trust which also helps you stay ahead of evolving global data privacy and cybersecurity regulations 
• Upgrade technology in current or older models of devices without having to replace existing infrastructure with fully backward compatible solutions 
• Dedicated customer support to reduce waiting time and uncertainty to resolve issues or accelerate your IoT roll out 

Conclusion 

ZARIOT IoT SIMs enable the rapid scaling of your IoT solutions, while futureproofing your business model. The additional capabilities allow you to easily manage devices and optimize operations, without compromising on security and reliability of data transmissions.
