Choosing a SIM · 27 October 2026

A business data SIM is a data-only SIM for the equipment a business runs: a 4G router, a card machine, a camera, an alarm or a sign. ThingSIM sells them online by card, with no contract, and bills each SIM only while it is switched on.

UK plans roam across all four UK networks, from £0.90 a month per SIM for 50 MB up to £8.85 for 5 GB, or across three networks (no EE) for less.

## Why not a phone SIM?

A consumer SIM assumes a person with a phone. It is tied to one network, it is billed every month whether it is used or not, and its terms often limit use in routers and other devices. A data SIM built for devices avoids all three. The [IoT SIM vs phone SIM guide](/iot-sim-vs-phone-sim) compares them in full.

## What you get

| | ThingSIM business data SIM |
|---|---|
| Networks | O2, Vodafone, Three and EE, or three of them for less |
| Contract | None; pay monthly by card, or a year up front |
| Billing | From the day each SIM is switched on |
| At the allowance | Pauses; upgrade straight away or wait for the reset |
| Failed payment | Pauses new orders and plan changes, never SIMs already working |
| Formats | Physical trio SIM (mini, micro, nano) or eSIM, £2.00 each once |
| Management | Portal and API: activate, pause, cease and change plan per SIM |

## Plans

| Plan | UK 4-network | UK 3-network |
|---|---|---|
| 50 MB a month | £0.90 | £0.65 |
| 250 MB a month | £1.20 | £1.15 |
| 1 GB a month | £2.40 | £2.25 |
| 5 GB a month | £8.85 | £8.20 |

Prices are per active SIM per month, ex VAT. Upgrade any SIM at any time, prorated.

## Choosing a size

Most business devices use far less data than a phone. A card machine or alarm communicator often fits in 50 MB a month. A router used as [broadband backup](/4g-broadband-backup) needs between 1 and 5 GB or more, depending on what fails over to it. A camera that uploads video needs the most. The [data guide](/how-much-data-does-my-device-need) works through common devices.

## Using a business data SIM in a 4G router

Put the SIM in the router, activate it in the portal and copy the APN shown against it into the router's mobile settings. [Setting up a 4G router](/setting-up-a-4g-router) covers the steps. If you need to reach the router from outside, add a [static public IP](/static-ip-sim-card) for £8 a month.

## Common questions
