EV Charging IoT Data SIM Cards
Multi-network data SIMs for chargepoint backhaul, OCPP sessions and payment terminals — because a charger that cannot authorise is a charger earning nothing.
Chargers go where the parking is
Bays are chosen for access, grid capacity and footfall. Nobody surveys the signal first, and a great many chargepoints end up in exactly the places cellular struggles: underground car parks, concrete podiums, kerbside next to a tall building.
Up to four networks, one SIM
In the UK, France and Spain a Wave SIM reaches four operators. In Germany, Italy and Ireland, three. Indoor and below-ground coverage differs sharply between them, so the unit picks whichever actually penetrates.
Profile changes without an engineer
On hardware that supports remote provisioning we load or switch the network profile for you from our side — no van, no opening a live cabinet. It depends on the device, so ask us whether yours qualifies.
Buy the data, not a contract
30-day and 12-month plans are bought outright, with no monthly tie and no minimum fleet size. Pooled data across a charging network is priced separately — tell us the estate and we'll quote it.
What an offline charger actually costs
More than the lost kWh. A charger that drops off is three separate costs arriving together.
Revenue that doesn't come back
A driver who cannot start a session does not wait. They drive to a competitor and, increasingly, they report the unit as broken in an app before they go — which costs you the next driver too.
Sessions that fail mid-charge
Losing backhaul partway through a session is worse than never starting one: a stopped transaction, an unhappy driver and a reconciliation problem with the roaming partner who brokered it.
A truck roll to find nothing
Most "charger faults" are connectivity, not hardware. Every one of those is a van, an engineer and a wasted afternoon, and it is the single most avoidable cost in running a network.
What you'll be connecting
Constant small traffic with bursts at session start and stop, plus the metering that has to be defensible.
What a chargepoint actually uses
Far less than people expect. The heartbeat is relentless but tiny; the cost comes from unit count, not per-unit volume.
An AC chargepoint
Roughly 50–150 MB a month on OCPP: a heartbeat every few seconds, meter values during sessions, and firmware checks.
A DC rapid
Roughly 200–500 MB a month with finer meter sampling, more diagnostics and a payment terminal on the same link.
A site gateway
Roughly 0.5–1.5 GB a month aggregating several units with load management. Refills reach 100 GB and pooled data has no cap if a site grows.
A single AC unit runs happily on a 6 GB / 12 month plan with headroom to spare. The decision on a network of any size is whether to give each unit its own plan or pool the lot — past roughly ten units, pooling is almost always cheaper and much less to administer.
These are indicative figures, not measurements of your hardware. Send us a month of traffic from one live unit and we will size the rest against it before you buy anything.
Plans for chargepoints and networks
Prices shown in your own currency. Most chargepoint controllers take a standard SIM, so check the slot before choosing the eSIM — though the eSIM is worth it on a sealed unit or one you would need a permit to open.

Common questions
Our chargers are in an underground car park. Will this work?
Sometimes, and reaching four operators rather than one materially improves the odds — but be realistic. Concrete and depth beat every network equally. If a handset shows nothing down there, plan for an external antenna run to the ramp or a wired gateway serving the units locally. That is a design decision, not a tariff one, and it is cheaper to make before installation than after.
Does OCPP need a static IP or a private APN?
Usually not. Modern backends have the charger open an outbound WebSocket, so nothing needs to reach it from outside and a standard APN is fine. Some older or enterprise setups do want a fixed address or a private APN — if yours does, tell us before you order, because it changes what you need.
What happens to a session if the network drops?
The SIM reselects to another operator automatically, and well-behaved chargers buffer meter values and reconcile when the link returns rather than killing the session. The exposure is a reconnect of seconds rather than a lost transaction — which is precisely the gap a single-network SIM cannot close, because it has nothing to reselect to.
Does the APN change when the SIM switches network?
No. The APN is set once in the controller and stays put through reselection, so one commissioning configuration works across every unit you install regardless of which operator a given site attaches to.
What if a unit uses more than its plan?
Nothing auto-bills at a surprise rate. Refills on a prepaid plan go up to 100 GB, so a busy site is a top-up rather than a migration, and the portal can notify you before a plan runs out rather than after. Across a network, pooled data has no cap and is quoted — usually simpler than a plan per unit.
