Your devices don't fail at random, they fail for a reason. A 7-business-day technical diagnostic for fleets on cellular networks: we isolate the cause of each failure — drops, excess data usage, poor battery life — and, depending on what it turns out to be, we tell you what action to take: from a parameter to fix to a documented case to escalate to the operator.
Request a free quoteFailure example. This device looked like it was losing coverage three times a day. The diagnosis showed these weren't network drops: the modem was leaving power-save mode badly and re-registering. Action for this case: fix the PSM timer. No hardware change needed.

Most of these failures don't originate in the device. They originate in how the device behaves against the network: how it registers, how it holds the session, how much it retries, how it enters and leaves power-saving modes. That layer is invisible from the firmware and from the IoT platform dashboard.
So the team ends up swapping hardware, switching providers and trying configurations until something appears to work. And the problem comes back.
The work runs the other way: first we isolate, with evidence, what is causing the failure; then, depending on what it turns out to be, we point to the concrete action it calls for — a parameter to fix, the APN, the data profile, or the documented case for you to escalate to the operator.
Every vertical breaks in a different way. These are the scenarios we work in.
Silos, irrigation, livestock monitoring. Devices in marginal coverage, where signal margin decides whether the data arrives.
Water, gas and electricity. Meters in basements and enclosures: indoor coverage and batteries that must last years without a visit.
Fleets and assets in motion. Constant cell changes, drops on route and data usage that spikes with no visible cause.
Alarms and access control. The connection has to be there when it matters, and drops get mistaken for real events.
Process telemetry in environments with metal structures and radio-frequency noise that degrades the link.
Lighting, parking, waste. High device density and rollouts that grow faster than planned.
Three recurring situations. For each one: what the diagnosis shows and what action it points to, depending on what is found.
The diagnostic runs on data you already have. Without these three there is no analysis, so it's worth confirming them before we start.
A read-only user on your SIM management platform. That's where fleet sessions, volumes and connection events come from.
Logs from at least three units with the problem, plus one healthy unit as reference. Modem logs or your platform's logs both work.
One device of the same model, on loan for the duration of the diagnostic, with its SIM. That's what makes it possible to reproduce and measure the behaviour.
On network access. We work from the device side and from your own connectivity data. We do not access the operator's infrastructure. When the analysis points there, the deliverable includes the documented technical case — evidence, timestamps, cause codes and cells involved — so you can escalate with backing instead of a generic report.
One hour. Fleet, symptoms, priorities and what data is needed.
Access to the connectivity portal, device logs and a test unit.
The technical work: the cause of each failure is isolated, with evidence.
Each root cause with its evidence and the action it points to for that case.
One hour to walk through the findings and answer questions.
Two sample reports, with fictitious data, to see the real level of detail of the deliverable.

A more specific solution: our developers write custom C firmware for your exact device — not a configuration tweak, but bespoke firmware development for your particular hardware.
EDRM© stores the cause of every network rejection, attach attempts, the last cell, geographic coordinates and signal strength right on the device. When the signal comes back, you get an SMS with the key data. So the next diagnosis is remote instead of a field visit — with the coordination, time and money that a visit costs.
This is how it arrives. A short message with everything needed to diagnose without a site visit.
With this you have what you need to escalate the case to your carrier: the specific cell, the EMM (EPS Mobility Management) cause code from the 3GPP standard, and the geographic coordinates of the area with drop issues. This is solid evidence to escalate the case to your network operator.
We're a team with more than 20 years of experience in telecommunications. We're passionate about technology — open source software, hardware, innovation — and challenges are exactly what drives us.
We built this service out of a real need: most connectivity problems get patched, not solved — the symptom eases but the cause stays. Our job is to get to that cause.
We sign a non-disclosure agreement before receiving any data. Fleet information is not used in any other engagement or as a case study without written authorisation.
