What is the difference between an IoT SIM and an M2M SIM?

M2M (machine to machine) is the older term for devices that talk to each other over a network. IoT (Internet of Things) covers the same idea at larger scale. For SIM cards, the two terms mean the same thing.

How much data does an IoT device need?

It depends on the device. Telemetry and status updates can use under 1GB a month, while CCTV and routers can use far more. Tell us the device and we can suggest an allowance.

Can I order IoT SIM cards in bulk?

Yes. Contact our team with the number of SIMs and devices you plan to connect, and we will quote for the volume.

Do IoT SIMs work in a phone?

Some do, but IoT SIMs are built and priced for devices that send data. For a phone, a SIM only plan with calls and texts is a better fit.

IoT & M2M Data SIM Cards

An IoT SIM card, also called an M2M SIM card, connects machines rather than people: routers, CCTV, sensors, meters, trackers and other devices that send data on their own. GleeSim's IoT and M2M range covers fixed IP SIMs, multi-network SIMs and unlimited data SIMs, on UK networks with roaming for the EU, USA, North America, and the Middle East and Africa. Plans start at £19.99 a month.
