PoC Radios UK | Push-to-Talk over Cellular (4G/LTE)

PoC radios (push-to-talk over cellular) give instant, nationwide UK communication over the 4G and LTE networks. There is no repeater to install and no Ofcom radio licence, because the radio works through a SIM rather than its own frequency.

They suit delivery fleets, multi-site security and lone workers who need coverage beyond a single site, with GPS built in. For on-site coverage compare licensed two way radios; for short-range licence-free use, see walkie talkies.

How PoC radios work

A PoC radio looks and handles like a normal two way radio, but inside it carries a SIM and sends your voice over 4G/LTE (falling back to 3G or Wi-Fi) to everyone in your talk group. If there is mobile signal, your team is in range — on site, on the motorway or at the other end of the country. Our PoC radios explained guide walks through it in full.

What PoC costs to run

PoC needs no Ofcom radio licence, but each device carries a SIM and an annual server licence — a modest per-radio subscription rather than the one-off £75/5-year Ofcom fee of conventional radio. For teams that genuinely roam, that trade is easily worth it.

When PoC beats conventional radio

Choose PoC when your team is spread across sites or on the move — multi-site security, delivery and logistics fleets, lone workers, and split-site operations such as care groups, schools on trips and colleges. Choose conventional DMR two way radios when everyone works on one site — no monthly cost, and they keep working if the mobile network goes down. For short-range licence-free use, see walkie talkies.

PoC radio FAQs

Do PoC radios need an Ofcom licence?

No — they use the mobile network, not licensed radio spectrum, so there is no Ofcom radio licence. You pay a SIM and annual server subscription instead, and we set the whole thing up before dispatch.

What does a PoC radio cost to run?

A per-radio SIM plus an annual server licence — typically a modest subscription. There is no repeater to install and no Ofcom fee. We will quote the running cost alongside the hardware.

What happens where there is no mobile signal?

A pure PoC radio has no coverage without a network. For critical use, a hybrid device that also runs DMR, or a conventional two way radio fleet for on-site work, covers the gap.

PoC or conventional two way radio?

PoC wins for nationwide, multi-site and mobile teams; conventional DMR wins for single-site coverage with no monthly cost and no dependence on the mobile network. Many operations run both.
