Mobility Refreshment: Modernizing IoT Data Lines for 800+ Users

Background

A regional organization operating a distributed, field-based workforce relied on approximately 800 to 850 active data lines to keep staff connected while working outside of the office. The lines served a straightforward but critical purpose — enabling staff laptops to access organizational systems and data in the field without depending on WiFi or a wired LAN connection.

The organization’s mobility spend was running around $16,000 per month, with roughly 90% of lines on AT&T across a tiered structure of 2GB, 5GB, and Unlimited plans. The Unlimited tier, priced at $25 per line, was reserved for staff with the highest data demands — either those who genuinely required it for their role or those who had been escalated after repeatedly hitting their data caps. Average monthly spend sat at $16,000 with no clear path to reducing it under the existing setup.

The Problem

The mobility environment had grown into a management burden that created friction at nearly every level of the organization.

Line management was almost entirely manual. Activating a new line, upgrading a user to a higher data tier, or downgrading a user who no longer needed extra data all required reaching out directly to an AT&T representative or combing through spreadsheets to identify candidates for plan changes. There was no self-service or centralized dashboard — just email chains and rep calls.

When staff members hit their data limits mid-month, they were throttled to speeds so slow the connection became essentially unusable. They had to wait out the monthly refresh cycle with no options for a quick resolution without manual intervention.

Physical SIM cards were the standard deployment method, which introduced a logistical problem of their own. Any SIM swap required a field technician to physically pick up a new SIM and travel to the device’s location to install it — adding cost and delays to what should be a simple administrative task.

Perhaps most limiting was the lack of visibility. The organization had no insight into what staff data usage was actually going toward, making it nearly impossible to make informed decisions about plan assignments or identify misuse. Leadership had expressed a clear desire to move to an eSIM-based solution that could be deployed through their existing Microsoft Intune MDM environment — but no solution had been identified yet.

Our Solution

NetSphere sourced a T-Mobile alternative that addressed every dimension of the problem — cost, management, visibility, and deployment.

The new solution provided 5G Unlimited lines with a 50GB soft throttle threshold — a significant step up from the tiered AT&T structure that was leaving users stranded mid-month. Through negotiation, we secured pricing at $15 per line for the full 800-line footprint, then pushed further and brought the rate down to $10 per line for 500 lines, restructuring the deployment to maximize savings without sacrificing coverage.

On the deployment side, the solution supported eSIM provisioning through Microsoft Intune, eliminating the need for physical SIM cards on compatible devices. The Intune push achieved a 60% success rate across the device fleet, with the remaining devices handled through a follow-up rollout method using manual eSIM configuration via QR code scan — ensuring full coverage without requiring field technician visits for the majority of activations.

The new platform also delivered the centralized management dashboard the organization had been missing — giving the internal team direct control over line activation, plan changes, and usage monitoring without needing to route every request through a carrier representative.

Results

The path to savings came through a deliberate multi-carrier negotiation strategy rather than a simple carrier swap.

NetSphere secured a commitment from T-Mobile for 250 lines at $10 per line for unlimited 5G data. We then brought that offer to Verizon, who agreed to a price match at the same $10 rate — but at a 700-line commitment. Armed with two competitive offers, we took both to AT&T and used them as leverage. AT&T responded with a $15 bill credit per line on their Unlimited plan, effectively bringing their $25 per line rate down to $10 — matching the competition without requiring a full migration away from AT&T.

With three competitive offers on the table, the decision came down to coverage and operational practicality. T-Mobile was selected for approximately 300 lines covering areas where their network outperformed AT&T. The remaining 500 to 550 lines stayed with AT&T — no migration required, same cost, better rate. The organization got the savings and the improved data plans without the disruption of moving the entire fleet to a new carrier.

Monthly mobility spend dropped from approximately $16,000 to around $10,000, representing roughly $6,000 in monthly savings and over $72,000 annually. Staff on the T-Mobile lines saw data speeds improve significantly — from approximately 200 Mbps to 400 Mbps. The eSIM rollout through Intune reduced the need for physical SIM management, and the organization gained full visibility into data usage across all lines for the first time.
