IoT Data Plans
Connect trackers, sensors and other M2M devices with a data plan sized for your deployment. Compare individual or pooled allowances, network access and operating locations.
Choose an IoT SIM plan around the device, not a phone tariff
Every IoT deployment is different. Some devices send a few kilobytes per day, others stream video continuously. Our IoT data plans are designed to be flexible — choose individual allowances or shared data pools across your entire SIM estate.
Single-network and multi-network options serve different requirements. For a fixed sensor, test reception where the unit is installed; for a tracker, consider the routes it travels. Available networks, supported radio technology, roaming arrangements and device compatibility depend on the SIM and plan quoted. A multi-network option is not a guarantee of coverage at every location.
Sizing is where IoT deployments usually go wrong, in both directions. A tracker sending a position every few minutes uses a trivial amount of data and is frequently put on a plan built for something far heavier; a camera or a telemetry unit sending images is put on a small allowance and overruns it every month. The useful exercise is to work out what a single device genuinely sends in a day and multiply, rather than starting from a tariff.
The other decision is pooled against individual allowances. A pool can suit an estate where some devices are busy and others quiet, but it can still be exhausted by unexpected usage. Individual allowances make per-device budgeting clearer; they do not by themselves guarantee a spending cap. Confirm overage rates, alerts, any barring options and what happens when a device or the whole pool exceeds its allowance.
Before ordering an IoT or M2M data plan, record the number of devices, typical and peak monthly data per unit, UK locations or overseas destinations, and whether the device needs to reach a private application. Check the SIM format and modem specification, then pilot representative devices in their real operating environment before rolling out the whole estate.
IoT data allowance examples
Start with measured data use per device, including uploads and downloads, then multiply by the number of operating days and devices. These illustrative 30-day examples are not a tariff, a device benchmark or a recommended allowance. They use decimal units: 1,000 MB = 1 GB.
| Devices | Daily data per device | 30-day data per device | 30-day estate total |
|---|---|---|---|
| 100 | 2 MB | 60 MB | 6 GB |
| 500 | 2 MB | 60 MB | 30 GB |
| 100 | 20 MB | 600 MB | 60 GB |
An application payload is not necessarily the whole connection’s data use. Check what your measurement includes, such as protocol traffic, retries and firmware downloads, and compare typical months with peak activity. Confirm how the proposed plan measures usage, any billing increments, pool eligibility and out-of-bundle charges. A 6 GB estimate does not establish that a 6 GB plan is available or sufficient; a shared pool is not automatically a spending cap. Test representative devices on the intended networks and locations before committing to a rollout. See GSMA’s IoT service testing guidance.
Prepare an IoT plan comparison
- Record the device count, modem specification, SIM format and where each unit operates, including any overseas destinations.
- Measure normal and peak data use, reporting frequency, update traffic and the consequences of a device going offline.
- Compare individual allowances with a shared pool, then confirm activation charges, minimum terms, alerts, restrictions and overage rates.
- Describe the application the devices need to reach and any private-routing requirement. Do not include SIM credentials, account passwords or device access keys in the enquiry.
Plan Features
Network Choice
Compare single-network and multi-network SIM options against real reception, device compatibility and the networks included in the plan.
Individual or Pooled Data
Size allowances for your device estate and check overage rates, usage alerts and any available controls before ordering.
UK and International Use
Check the countries, networks, rates and roaming conditions needed for logistics, tracking or other cross-border deployments.
Who we work with
We are independent of any single network or vendor, so the recommendation follows the requirement.
Mobile networks
We are not tied to one network, so the tariff follows the coverage your teams actually need.

IoT Data Plans — Common Questions
Can data be shared across all my SIMs?
A shared pool can be an option for an estate whose devices use different amounts of data. Confirm which SIMs participate, how the pool is billed, what happens when it is exhausted and whether usage alerts or restrictions are available. Sharing an allowance does not remove overage risk or automatically cap the cost of a faulty device.
Do IoT SIMs work outside the UK?
International options are available, but supported countries, networks, rates and roaming conditions depend on the SIM and plan. Provide the destinations and duration of use before ordering. Check device compatibility and test a representative unit, rather than assuming a UK deployment and an overseas deployment have identical coverage or charges.
How do we work out what allowance we need?
From what one device actually sends in a day, multiplied up — not from a tariff. A tracker reporting a position every few minutes uses a trivial amount; a unit sending images uses orders of magnitude more. Getting this wrong is the commonest problem in IoT deployments, and it happens in both directions: overpaying on most estates, and overrunning every month on a few.
How are IoT data plans priced for a business deployment?
The quote depends on device count, expected usage, individual or pooled allowances, network access and where the SIMs operate. Include typical and peak data use, any private routing requirement and the device specification. Compare the minimum term, setup charges, out-of-bundle rates and management options as well as the monthly data price.
Can an IoT SIM automatically use every UK mobile network?
Do not assume that multi-network means every operator or that a device continuously selects the strongest signal. The networks and selection behaviour depend on the SIM, roaming arrangements and modem. Ask which networks and radio technologies the proposed plan supports, then test reception and reconnection behaviour where the devices will actually operate.
