IoT SIMs · business connectivity

IoT SIMs for the devices your business relies on.

Alarms, cameras, card machines, lifts and chargers increasingly need a mobile connection, especially as copper phone lines close. We supply IoT SIMs on multi-network or single-network plans, with one bill and a UK team behind them.

  • Multi-network or single-network SIMs
  • One bill for every device
  • Hardware and installation available

What they connect

If it needs to stay online, a SIM can do it.

Any device that sends an alert, a reading or a video feed can run over a SIM. These are the jobs we’re asked about most.

Lift emergency lines

4G SIMs and autodiallers for lift alarms. See lift line SIMs →

Alarms, fire panels and door entry

Signalling for intruder alarms, fire panels and door entry systems that used to dial out over a phone line.

CCTV and remote cameras

Connect cameras on building sites, car parks and yards where there’s no broadband.

Card machines and kiosks

Reliable connections for payment terminals, vending machines and self-service kiosks.

EV chargers and telemetry

Smart chargers, meters, sensors and remote monitoring equipment.

4G broadband backup

A SIM in your router keeps the office online if the main broadband line drops.

Network options

Roaming or single network: your choice.

Multi-network SIMs switch automatically to the strongest network available, so a device stays online if one network has a problem. Single-network SIMs cost less and suit sites where one network’s coverage is strong.

  • Multi-network: switches to the strongest signal automatically
  • Single network: lower cost where coverage is strong
  • Data on both, plus voice where the device needs it

Multi-network roamingCritical devices and patchy signal: lifts, alarms, remote cameras
Single network (O2, Vodafone or EE)Sites with strong coverage on one network, at a lower cost

PSTN switch-off

Many devices that dial out over a phone line need a new connection before the copper network closes. A SIM is usually the quickest fix.

31 January 2027 is when the copper phone network closes.

Questions

IoT SIM questions.

Can’t see yours? See all FAQs or just give us a call.

A SIM designed for devices rather than phones, such as alarms, cameras, card machines, chargers and sensors. It’s built for always-on use and managed in bulk.

A multi-network SIM switches to the strongest network available, which suits critical devices and patchy signal. A single-network SIM uses one network and costs less.

Yes, where the device needs it, such as a lift autodialler. Most IoT devices only need data.

Most devices that take a standard SIM will work. Tell us the make and model and we’ll confirm before you order.

Yes. We can supply and fit routers, autodiallers and other devices, and test them on site.

It depends on how many SIMs you need, the network option and the data each device uses. Tell us what you’re connecting and we’ll send a fixed quote.
