Mobility Refreshment: Modernizing IoT Data Lines for 800+ Users

800 Lines. $16,000 a Month. No Visibility.

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. Average monthly spend sat at $16,000 with no clear path to reducing it under the existing setup.

Manual Processes, No Visibility, Physical SIMs

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. There was no self-service or centralized dashboard, just email chains and rep calls.

When staff hit their data limits mid-month, they were throttled to speeds so slow the connection became essentially unusable — and there was no quick resolution without manual intervention. Physical SIM cards compounded the problem further: any SIM swap required a field technician to physically travel to the device’s location, adding cost and delays to what should be a simple administrative task.

Perhaps most limiting was the complete 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.

T-Mobile 5G eSIM — Sourced, Negotiated, and Deployed Through Intune

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 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.

$6,000 Less Per Month. Twice the Speed. Full Visibility.

The most immediate impact was financial. Monthly mobility spend dropped from approximately $16,000 to around $10,000 — a reduction of roughly $6,000 per month, or over $72,000 annually. Unnecessary administrative fees tied to the old carrier relationship were eliminated as part of the transition.

• The team gained full visibility into staff data usage for the first time, enabling informed decisions about plan assignments and giving leadership the oversight they had been asking for. Upgrading or downgrading a line no longer requires a call to a carrier rep — it’s handled directly through the management portal.
• The eSIM rollout integrated cleanly with the organization’s existing Intune MDM environment, with the majority of devices provisioned remotely without any field technician involvement. For devices that required the QR code method, the process remained simple and didn’t require specialized technical support.
• Data speeds doubled as part of the carrier switch — average speeds improved from approximately 200 Mbps to a sustained average of 375 Mbps, giving field staff a noticeably faster and more reliable connection while working outside the office.
• The organization went from a costly, manually managed, visibility-blind mobility environment to a modern, centrally managed, eSIM-enabled platform — at a meaningfully lower cost per month.
