One IoT SIM,
All the Best Networks
Built for IoT
IoT SIM cards might look identical. But there is more than meets the eye. The Simbase IoT SIM uses multi-IMSI technology or eUICC to automatically switch between carriers and deliver the best available connection, wherever your devices go.
Local & Global
On-Demand
Low Data Costs
Whether you're optimizing for local rates or scaling globally, the Simbase IoT SIM gives you full control. Instantly switch between local and global coverage, no hardware swaps or new contracts. Our multi-network SIMs connect to the best available network in each country, delivering reliable, high-performance connectivity backed by our global infrastructure.

Never get charged for what you don't use
Simbase operates on a pay-as-you-go model. With a small daily access charge, your devices can connect to over 400 mobile networks worldwide. The daily charge applies only when your IoT SIM is active, so you pay only for the days you need connectivity.
Coverage that scales with your business
Start on simple zone based pricing. Whether your devices stay local or go global, you pay local rates in each country. Need more control? Build your own coverage plan with per network billing and pay carrier cost plus a clear markup to optimize performance and spend. One SIM that grows with you.

IoT SIM cards are managed via our SIM platform, which helps in simplifying this SIM management process. Providing granular insights into usage, troubleshooting connection errors, and a far more favorable pricing model for cellular IoT data than traditional data plans
An IoT SIM card looks the same as a standard SIM card. But unlike traditional SIMs, it has a few features in order to make it compatible with IoT devices. The focus of an IoT SIM card is for it to send and receive data, more than its capability to make voice calls. It comes with features that help manage and monitor these devices remotely.
An IoT SIM card is a small microchip that holds the unique information about the SIM and therefore the subscriber. When a connection is established information about the subscriber is shared with the carriers. With this information, the carrier can allow the SIM to establish a data session, roam on foreign networks and bill the usage of the SIM card.
The greater level of control over the IoT SIM cards in the Simbase core, allows to share more information about its connection in our dashboard. Unlike traditional SIMs, the IoT SIM card from Simbase provides remote device access, enhanced security features and can change the available networks at any time.
Yes, one of the major benefits of using an IoT SIM card from Simbase is the option to use many networks on a single SIM. For example, in the US, it can connect freely with both AT&T and T-Mobile to achieve a more reliable connection. For businesses of all sizes, new opportunities may come anywhere in the world. The IoT SIM allows to extend coverage to any country via the SIM platform.
IoT SIM cards are small and come in a variety of form factors. The most common form factor is a multi-sized triple-cut IoT SIM. This plastic SIM card holds all four common SIM card sizes in a single SIM. This way, you are certain the SIM will fit your device. All Simbase IoT SIMs are in this multi-size form factor.
The 4 SIM sizes:
For device makers, there is also an embedded chip SIM card available. The MFF2 chip SIM can only be soldered to the device at production and is non-removable.
The Internet of Things (IoT) is about connecting physical objects to the Internet. There is no need for human interaction. IoT SIMs are called machine-to-machine SIM cards or M2M SIM cards interchangeably.
Both an IoT SIM card and an M2M SIM card are about connecting devices to the internet without human interaction. The M2M terminology is around for a longer period. We often associate M2M with telematics applications, like GPS trackers and vending machines.
No, IoT SIM cards do not necessarily need a phone number. They use the mobile network for data transmission, not for standard voice calls or SMS like a mobile phone. The SIM card in IoT devices is used to authenticate the device on the network and to manage the data connection. However, in some cases, a phone number may be assigned to an IoT device for SMS communication or for data plan purposes, depending on the requirements of the application.
Yes, many IoT devices use SIM cards. These IoT SIM cards allow devices to connect to cellular networks for data transmission. IoT SIM cards are used in a variety of devices for different applications, including fleet management, smart agriculture, smart cities, and much more.
An eSIM, or embedded SIM, refers to a type of SIM card that is built directly into a device and is not physically removable. The main advantage of an eSIM is its potential for remote provisioning, meaning it could be programmed to use a specific network provider. However, the ability to switch between network providers is contingent on the agreement you have with a network operator like Simbase.
An IoT SIM, conversely, refers to a type of SIM card specifically designed for Internet of Things (IoT) devices. While an IoT SIM can take the form of a standard, removable SIM card, it can also be an eSIM. The defining characteristic of an IoT SIM is its focus on providing data connectivity for IoT devices. It usually features enhanced capabilities such as global roaming, automated network selection, and more advanced data management options that are specially designed to cater to the unique demands of IoT devices. So, while all eSIMs used in IoT devices can be considered IoT SIMs, not all IoT SIMs are eSIMs.
IoT SIM cards are being used in a wide range of applications across numerous industries. Some examples include:
Essentially, any device that needs a wireless data connection could potentially use an IoT SIM card.
In the ever-expanding IoT market in the USA, numerous providers offer IoT SIM cards. These providers cater to various IoT application needs, considering factors such as data consumption, global coverage, network reliability, and more.
One of the leading IoT SIM cards offers for the USA is from Simbase. Known for its wide-ranging offerings, Simbase provides SIM cards specifically designed for IoT devices. It offers global coverage and flexible data plans to accommodate different IoT requirements.
Choosing the right IoT SIM card provider is crucial. When making a decision, it's important to consider the specific needs of your IoT devices and applications. For a comprehensive solution that balances coverage, flexibility, and cost, Simbase is an option worth considering. Buy your IoT SIM cards at affordable prices today.
