The Internet of Things (IoT) is changing the way we interact with the world around us. More and more everyday objects are now connected, making our working and personal lives more efficient. This new connected world is possible through a network of IoT SIM cards that transfer millions of terabytes of data across the globe every day.

What is an IoT SIM CARD?

Whilst an IoT SIM card looks just like a traditional SIM that you will use with your mobile phone, these data-only SIM cards have a few key differences that set them apart from the SIM cards you may have seen before:


The first thing you need to know about an IoT SIM is that they must be reliable. V12 IoT SIM cards are designed to stay connected, even when individual mobile networks go down.

We achieve this by using a Multi-Network SIM; these SIMs automatically switch carriers if there is a loss of signal. We use un-steered SIMs, meaning that the SIM is free to choose the best-performing network, without any interference from us.

System Integration

You can instantly and securely access data and automate your connectivity using our API (Application Programming Interface).

IMEI locking

Your IoT SIMs can be locked to a specific address, preventing any type of misuse or tampering. If you want to use the SIM with a different device, we can simply amend the IMEI lock.

Fixed IPs

Our Multi-Network SIMs can be allocated with either public or private static IP addresses as appropriate, to meet specific requirements.


An IoT SIM offers unparalleled flexibility. It can adapt and work with a range of needs and use cases, from monitoring offshore wind farms, to updating a network of digital display boards across the country.

Our IoT SIM cards can be delivered in a wide range of bespoke packages to match individual customer requirements.


As your business grows, our customer portal gives you complete oversight of your estate, allowing you to easily understand how all your SIMs are performing, no matter how many you have.


All of our IoT SIMs are designed to only transfer data, ensuring that you have the best experience, without the complications of receiving spam calls or texts.

Where can IoT SIM Cards be used?

With the rise of IoT, there is no limitation to where you can use an IoT SIM card. IoT SIM cards have been used in a wide range of projects, from helping farmers to automatically guide tractors, to keeping our streets safe by transmitting data from police body cams and so much more.

Wherever you choose to take your technology, a V12 IoT SIM can be there to help you monitor, transmit or receive many forms of data, revolutionising the way you work.

What is the best SIM card for IoT devices?

V12 IoT SIMs are designed to keep you connected, whatever your situation or needs in the UK and abroad. At V12, we have over 20 years of experience working within the telecommunications industry, and we have built a reputation for reliability and innovation.

What Networks do V12 use?

We are proud to say that our un-steered Multi-Network SIMs can seamlessly access all four of the UK Mobile networks (O2, Vodafone, EE & 3) ensuring you can always access the strongest available signal.
