Why your charge points lose connection
A single-carrier SIM — or a multi-carrier SIM that favours whichever network costs the carrier least — is a single point of failure. In an underground car park, a rural area or a remote site, your charge point goes down: you have to reboot the station, the SIM or the router, and your customer is left stranded.
Insufficient coverage
In an underground car park, industrial site or rural area, a single-carrier SIM exposes you to blind spots. Orange doesn't cover the same 1% as SFR.
OCPP session lost
Traditional steering takes 30 to 90 seconds to switch carriers. The OCPP transaction drops. The customer can't charge — and you get a ticket.
€300 call-outs
Every call-out for an offline charge point costs between €150 and €400. Without real-time monitoring, you always step in too late.
One SIM. Four networks. Simultaneously.
Not roaming, not failover. All 4 carriers are connected at the same time — the best signal takes over in under a millisecond.
Simultaneous connection to all 4 carriers
The SIM is registered on Orange, SFR, Bouygues and Free at the same time. No selection — the best antenna at every moment.
Private APN + OpenVPN tunnel
Your charge points on an isolated closed network. OCPP sessions never travel over the public internet — native GDPR compliance.
Real-time PRISM monitoring
Status of every SIM, data usage, disconnection alerts. Included at no extra cost in all plans.
Pooled data — no individual overage
All your SIMs share a common pool. A stable, predictable bill, even for mixed fleets.
Everything so you never set foot on site again

What you see in real time across your fleet
Screenshots taken from the PRISM platform. Not a sales pitch — what your technicians see every day.
Carrier switch with no manual action
The attachment history shows automatic transitions between Orange and SFR on the same SIM — in 2G/3G or 5G depending on the best coverage at any given moment.
2 data sessions open on 2 separate carriers
The SIM keeps two active network paths in parallel. If one degrades, the other is already established — no OCPP session drop possible.
Carrier visibility + corrective actions without travel
PRISM shows the active carrier, IMSI and timestamp. In one click: forced network detach or re-attach — zero site visits.
Simple. Predictable. No surprises.
