What are M2M SIM cards?

Everything you need to know about Machine-to-Machine SIM cards, and how they differ from the SIM in your phone.

What are M2M SIM cards?
M2M (Machine-to-Machine) SIM cards let data be sent and received between 'machine' type devices - passing information from one device to another without the need for any human interaction.
How are they different to normal SIM cards?
The SIM cards in our mobile phones are built for everyday use. M2M SIM cards are far more durable, more secure and able to store more data - and they're designed for the way connected machines work, rather than the way a phone does.
What would you use an M2M SIM for?
There are many ways to use an M2M SIM card. A common one is vehicle tracking - if your business has a fleet of drivers, an M2M SIM lets you see exactly where they are, so you can keep your customers updated with an accurate ETA.
How much data does an M2M SIM use?
It depends heavily on the device. A simple sensor or alarm that only sends a short status update might use a few megabytes a month, while a vehicle tracker sending regular location pings typically sits in the low hundreds of megabytes. We size the data plan to the device, starting from 100MB and scaling up to 500GB for data-hungry fleets, rather than putting every SIM on the same allowance.
Do M2M SIMs work internationally?
Yes, most of our M2M SIMs support international roaming, which matters if your vehicles, equipment or shipments cross borders. Let us know where the devices will actually be used and we'll confirm coverage and any roaming charges upfront as part of your quote.
What network do M2M SIMs use?
Our M2M SIMs are multi-network, meaning a single SIM can connect across several UK mobile networks (such as O2, Vodafone, EE and Three) rather than being locked to just one. The SIM automatically uses whichever network has the strongest signal in that location, which matters for devices in vehicles or remote sites where coverage varies.
How do I manage lots of SIMs across a fleet?
All of your M2M SIMs sit on one account with one consolidated bill, rather than dozens of separate contracts. We can also set up usage alerts so you're notified if a device suddenly starts using far more data than expected, which is often the first sign of a fault or a security issue.
Is there a minimum contract length or fleet size?
No - we quote for anything from a handful of SIMs to several hundred. Smaller orders are typically on a rolling monthly contract, while larger fleets can access better per-SIM pricing on a 12 or 24-month term. Tell us roughly how many SIMs you need and we'll recommend the right contract length.

Built for connected devices

From tracking a fleet to powering remote sensors and machinery, M2M SIM cards keep your equipment talking to you wherever it is. Here are just a few of the ways businesses put them to work:

M2M SIM for Vehicle Tracking

Fitted into a fleet tracker, an M2M SIM reports live location, speed and mileage back to your system, so you can give customers an accurate ETA and spot inefficient routes.

M2M SIM for Vending & Payment Machines

Vending machines and unattended card terminals use an M2M SIM to authorise payments and report stock levels remotely, cutting down on wasted site visits.

M2M SIM for CCTV

Where fixed-line broadband isn't available or reliable, an M2M SIM keeps remote CCTV cameras and NVRs streaming footage back to a monitoring centre or app.

M2M SIM for Remote Sensors & IoT

Temperature, humidity, level and pressure sensors on remote sites report readings back over an M2M SIM without needing a fixed internet connection nearby.

M2M SIM for Alarms & Security Systems

Intruder and fire alarms use an M2M SIM as a resilient backup path to the monitoring centre, so an alert still gets through even if a site's broadband goes down.

M2M SIM for Machinery & Equipment Monitoring

Industrial machinery reports run-hours, faults and maintenance needs back to base over an M2M SIM, flagging problems before they cause downtime.

Why choose an M2M SIM card

M2M SIM cards are built for a different job than the SIM in your phone - and that brings a whole set of advantages.

Durability

M2M SIM cards are built to withstand vibration, extreme temperatures and moisture, with a typical life expectancy of up to 10 years compared with 2-3 years for a standard SIM.

Remote Access

Information on a device can be accessed easily from anywhere, without having to be physically near the device itself.

Multiple Networks

A single M2M SIM can be set up across several networks, so it always uses whichever one has the strongest connection.

Less Data Consumed

Most M2M devices only send short bursts of data rather than streaming, so many sensors and alarms use just a few megabytes a month and draw a fraction of the power of a phone.

Flexible Sizes

M2M SIM cards come in lots of different sizes, which means they can be fitted into a huge range of devices.

Lower Costs

Because M2M SIM cards are bought in bulk, fleets of 20+ SIMs typically see per-SIM pricing come in noticeably lower than a standard consumer SIM contract of the same size.
