While mobile SIMs and IoT SIMs serve the same purpose, the latter is specifically designed to handle the diverse business applications, varied data usage, unique network requirements, and scale and complexity of IoT devices. If you need to determine the best size and type of SIM for your device, we’ll share what to consider in the process and give insights on how to overcome SIM-related challenges with an experienced connectivity partner.  

What is a SIM card?

SIM (Subscriber Identify Module) cards store a unique ID that allows devices to connect to the cellular network, store information about a user or device, and send and receive data. SIM cards are small chips in plastic casings that come in various sizes or forms. Traditional or Consumer SIMs designed for phones are specific to a single carrier, like Verizon or AT&T, and store information about the user, like voice and data usage. This data is accessed by the carrier to determine a bill. Consumer SIMs aren’t scalable, flexible, or durable enough for IoT devices, and they don’t account for the technical and financial business models required to support them.

What are IoT SIMs?

IoT SIMs, referred to as Machine-to-Machine (M2M) SIMs, provide access to the network, store device and carrier information, and transfer data just like consumer SIMs. However, they’re also capable of supporting IoT devices in a variety of applications, such as security cameras, fleet tracking, or patient monitoring devices. Rather than one person needing one SIM card for one device, Original Equipment Manufacturers (OEMs) must manage thousands of devices with unique data usage and coverage requirements. Often, IoT devices require multiple carrier relationships or even permanent roaming and must be durable enough to survive in extreme conditions. With these needs of IoT devices in mind, IoT SIMs must

• Have flexible data plans to support different levels of usage,
• Be capable of mass activation, 
• Withstand harsh environments, temperatures, and vibrations, 
• Have a long lifespan (years longer than a traditional SIM),
• Allow for remote management of devices deployed on a wide scale,
• And support multiple carriers for extensive connectivity.

SIM card sizes

SIM cards are categorized by size or Form Factor (FF). SIM form factors decrease by the size of the plastic casing surrounding the SIM. Different form factors are suitable for different applications with devices of different sizes. The Standard SIM is the original and the largest but is no longer used in modern devices. Today, smartphones typically use SIM cards two–three sizes smaller–the Micro-SIM or the Nano-SIM. Devices also have the option to use a versatile Tri-Cut SIM card that comes in 2FF, 3FF, and 4FF form factors. 

1. Standard SIM (1FF)

Size: 85.6mm × 53.98mm × 0.76 mm

This was the precursor to the types of SIM form factors we see today. As more and more devices began to leverage cellular connectivity, smaller form factors were required and so the 1FF Standard SIM largely fell out of use.

2. Mini-SIM (2FF)

Size: 25mm x 15mm x 0.76mm

Sample use case: Large devices–Vending machines, ATMs, vehicles

3. Micro-SIM (3FF)

Size: 15mm x 12mm x 0.76mm

Sample use case: Portable devices–Routers, GPS systems

4. Nano-SIM (4FF)

Size: 12.3mm × 8.8mm × 0.67mm

Sample use case: Compact devices–POS systems, smartwatches and can also be used in devices like routers. 

Note: Over time, smaller form factors have gained prominence across different types of devices as manufacturers continue to pack more computing power into smaller spaces, making products smaller, lighter, and more cost-effective.

5. Embedded SIM (MFF2)

Size: 6mm × 5mm × 0.9mm

Sample use case: Outdoor, on-the-go devices–drones, fleet cameras

The Embedded SIM is the smallest and most durable SIM card and is a great fit for many IoT devices. IoT devices vary wildly in size and design in contrast to more standardized smartphone or tablet designs, so the embedded SIM form factor provides benefits due to its size and the fact that there is no need for a separate SIM slot that would otherwise take up precious real estate within a device. These SIMs are “embedded” when soldered into devices to strengthen their durability, making them appropriate for more extreme environments too.  

Specific types of IoT SIM cards

There are various types of IoT SIM cards available, which are not necessarily interrelated, but you should consider all of them before making a decision on which SIM card to choose.

eSIMs 

An eSIM could be one of two things. It could refer to the embedded SIM form factor or eUICC (Embedded Universal Circuit Card) software. The first describes a SIM soldered into a device, and the second is the software that enables remote provisioning and management of SIMs without requiring them to be swapped out. The software does not require a soldered SIM, comes in all form factors, and can be used for Consumer SIMs or M2M/IoT SIMs. When we discuss eSIMs, we’re referring to the eUICC software. 

Every SIM card is equipped with a UICC (Universal Integrated Circuit Card) that makes it identifiable on the network, but in general all SIM cards are associated with one network provider. This could limit the global coverage and roaming capabilities of a device if the single provider does not have roaming agreements with other carriers. 

On the other hand, an eSIM/eUICC allows a SIM to switch providers and leverage different roaming agreements. For example, Zipit offers SIMs for IoT with more than one network profile for global coverage. One eUICC SIM card can connect to multiple networks over the air without requiring access to the device–this enables faster device deployment and rapid global scalability. 

Learn more about what an eSIM is and if it’s right for your IoT device. 

Using global SIMs vs. SIMs from multiple carriers 

A global SIM is one SIM card capable of roaming by leveraging roaming relationships of multiple carriers. A multi-carrier SIM approach uses SIMs from multiple network operators in different regions. Utilizing a multi-carrier SIM approach or multi-SKU approach can provide better coverage on a global scale because they leverage local networks owned by a SIM’s regional carrier rather than relying on roaming agreements between carriers. Often, this approach is more reliable and cost-effective than using a global SIM.

The difficulty with using multiple SIMs comes with managing relationships and contracts with multiple carriers and efficiently managing SIM states or moving devices between plans. Certain carrier rate plans or very high data usage plans, like Fixed Wireless, are limited to a specific carrier offering those plans and do not allow for roaming. A 300GB plan would require multiple SIMs to offer the plan on multiple carriers.  Carriers have specific restrictions with each other on how much data can be used while roaming on another network.

You can streamline multi-carrier SIM management with our IoT connectivity platform and partner with Zipit to manage your connectivity with the world’s top cellular carriers. 

Learn more about the advantages, disadvantages, and uses of global and multi-carrier SIMs. 

Steered vs. Non-Steered SIMs 

Steered and non-steered SIMs behave differently when a device roams. No matter what alternative networks become available during roaming, a steered SIM will stay connected to the original carrier’s network or their preferred roaming list priority, even if the connection is weak. Non-steered SIMs, on the other hand, connect to the strongest available network by leveraging agreements between different carriers. Many IoT devices depend on non-steered SIMs for a continuous, stable connection.

How to choose an IoT SIM card

There are several different types and sizes of SIMs to choose from, and given the variability and complexities of IoT devices, the decision isn’t always straightforward. When choosing an IoT SIM card and provider, keep in mind the following.

1. Form factor–The size and design of the device determine the size of the SIM card and how much room it allows. 
2. Roaming–If your IoT device is moving across different countries or regions, you'll want to ensure that your SIM card provider has agreements with operators in those areas to avoid any disruptions in connectivity. You will need to choose between a single global SIM or a multi-carrier SIM approach or decide if an eSIM is the best solution. If your device is deployed in a remote location, you’ll want to choose a SIM card that allows for remote provisioning, but keep in mind that most mobile network operators around the world do not actively support eUICC yet. 
3. Connectivity–The location of the IoT device may impact the strength of the signal and the available coverage options. It's important to choose a SIM card with a carrier that provides sufficient coverage in the area where the device will operate. If your devices are located worldwide, multi-carrier SIMs are often the choice we recommend. 
4. Device environment–You’ll want to ensure that your device’s SIM is durable enough to withstand the environment of your device. 
5. Security–When choosing between a removable or an embedded IoT SIM, keep in mind that there may be a higher risk of theft with a removable SIM. If your device is located in an area where theft is a threat, an embedded SIM may be the better choice. 
6. Management platform–Accessing data and managing the connectivity of IoT devices requires a secure management platform. Zipit can provide you with the best IoT SIMs for your devices from top carriers, along with a single platform to manage and monetize your devices.
