Stop Guessing.
Know Exactly Why
Devices Fail to Connect.

When a device gets rejected from your private cellular network, your team shouldn't need a cellular expert or a weeks-long ticket queue to find out why. OneLayer captures every failed attach attempt, surfaces the affected subscriber and serving cell, classifies the cause, and provides a recommended fix, the moment it happens.

What It Does

Instant Root Cause Analysis
for Every Failed Connection

A dedicated Connectivity tab in your Monitoring page logs every attach attempt in real time. Whether a single subscriber fails to attach or a group of devices drops during a failover, your team sees who was affected, which cell they were on, why it happened in plain language, and exactly what to do next, without needing a separate tool to find out.

A Real-Time Log of Every Attach Attempt

The Connectivity tab records every attach request and response as it happens, by subscriber IMSI, serving cell, and timestamp. Identify a single rejected device or analyze a group of devices that dropped during a failover event. Nothing is missed, and your team always has the full picture.

Classified Cause With Plain-Language Description

Every rejection is mapped to one of four categories: Security & Authentication, Subscriber & Policy, Resource & Congestion, or Protocol & Configuration, alongside a plain-language description that any operator can read and act on. No 3GPP expertise required.

Recommended Actions Tailored to the Cause

Each failure entry includes a recommended action matched to its specific rejection reason. Not generic guidance, but targeted steps your team can follow to resolve the issue without escalating to a cellular specialist.

How It Works

Getting to Root Cause Takes Three Steps

No weeks of ticket queues. No calling in cellular experts. Just a clear path from failure to fix.

1

Connect

OneLayer connects to your network's control plane signaling, the same channel devices use to authenticate and register. From that point, every attach attempt is captured in real time, before any issue reaches your helpdesk.

2

Diagnose

For every failed attachment, OneLayer identifies the exact rejection point, classifies the cause into one of four categories, and surfaces the affected subscriber's IMSI alongside the serving cell they were trying to connect through.

3

Fix

You open the Connectivity tab, review the failure log, follow the recommended action matched to the specific rejection cause, and close the loop, in hours, not months.

Your Team Deserves More Than
a Ticket and a Month-Long Wait

What Our Customers Are Saying

"Cellular APN customers have struggled to identify and secure devices used across multiple carriers. OneLayer's platform provides the single pane of glass to monitor and enforce policies universally."

The Transformation

Imagine Starting Every Shift Already Knowing Why Devices Failed

Instead of waiting for a complaint, your team sees failures proactively, with cause, context, and a recommended fix already surfaced. No specialist. No separate tooling.


Operations acts, security spots patterns early, and your business trusts the network to scale. No unknown assets. No security gaps from invisible devices. Just a complete, accurate map of your entire private cellular network, giving you the confidence to manage, secure, and defend it.

Fix the right thing the first time

Know the failure category before a ticket is filed. Act on the real cause, not a guess.

Confirm resolution, not just failure

Verify a previously-failing device has reconnected, without waiting for a vendor callback.

A network your business trusts to scale

Visibility that empowers operations, enables security, and earns confidence across the organisation.

Give Your Network Team the Visibility They've Been Missing

Your operations team shouldn't need a cellular expert, or a costly dedicated analyzer, to answer the question: why won't this device connect? Give them the log, the label, and the next step, proactively, the moment it matters.
