M2M (machine-to-machine) data SIM cards are built for routers, gateways, meters and sensors rather than phones – data-only, manageable in bulk, and designed to run reliably for years. Our M2M SIMs roam across UK mobile networks and are available with dynamic IP from £2.20/month, private IP with VPN, or fixed public IP.
Built for fleets, not phones
If you’re deploying SIM cards into routers, IoT gateways, vending machines, meters or sensors – whether that’s five devices or five hundred – an M2M SIM is designed around that use case. Data allowances are pooled across every SIM on the account, so devices that use less than their share cover devices that occasionally use more, without needing to manage individual top-ups. A free online portal gives visibility of usage and connection status across the whole fleet.
Choosing data and IP options
M2M SIMs are available across all of our data tiers and IP types. For most devices that only need outbound connectivity, dynamic IP roaming SIM cards starting at £2.20/month for 1GB are the standard choice. If your devices need remote access – for management, monitoring or troubleshooting – see private IP roaming SIM cards with VPN.
For help estimating data usage across a fleet of devices, see our guide on choosing a data allowance for IoT, or get in touch with details of your devices and we’ll help size the right plan.
Managing your SIM fleet
Every M2M SIM includes access to our online SIM management portal, where you can monitor data usage per SIM, set up alerts for unusual usage, and see connection status across your whole estate. This becomes particularly valuable as deployments grow beyond a handful of devices.
