Overview

Standardize AT&T-based machine connectivity on purpose-built hardware. This Skyus SC configuration delivers LTE Cat 4 service — up to 150 Mbps downlink class — with 3G fallback over a single USB 2.0 mini-B interface. Compact, rugged, and low-power, it gives SD-WAN edges, industrial hosts, and unattended equipment a dependable AT&T cellular WAN path backed by a one-year warranty.

  • LTE Cat 4 with downlink performance in the 150 Mbps class
  • 3G fallback for coverage beyond the LTE footprint
  • AT&T carrier configuration
  • Single USB 2.0 type mini-B interface for power and data
  • Built-in connection manager for unattended hosts
  • Compact, rugged, low-power Skyus SC platform
  • One-year warranty
  • Deploy AT&T-matched hardware with one activation process fleet-wide

Carrier-specific hardware removes variables. This Skyus SC variant is provisioned for AT&T service, which means devices arrive matched to the network they will run on — no band checklists per site, one activation process, and one carrier support path when something needs troubleshooting. For fleets standardized on AT&T data plans, that consistency is worth more than multi-carrier flexibility.

The modem itself is the industrial-grade Skyus SC platform: LTE Cat 4 connectivity in the 150 Mbps downlink class, with 3G fallback extending reach where LTE coverage is thin. The single USB 2.0 mini-B interface both powers the modem and carries data, so integration into an enclosure or onto an SD-WAN appliance is a one-cable exercise. A built-in connection manager keeps link behavior predictable on unattended hosts, and the compact, low-power design suits continuous duty in tight spaces.

In the field, the SC typically plays one of two roles. As a primary WAN it connects equipment that has no wireline option — remote cabinets, mobile assets, machine retrofits. As a failover leg it gives SD-WAN branches an inexpensive cellular path that activates when the wired circuit fails. Either way, Inseego's IoT Connect cloud provides fleet visibility and management, and a one-year warranty covers the hardware. Companion Skyus SC variants serve Verizon-only and carrier-flexible deployments, letting mixed fleets share one hardware family.

Ideal for

  • AT&T-standardized connectivity for kiosk and vending fleets
  • Primary cellular WAN for remote cabinets and machine retrofits
  • Failover USB WAN on SD-WAN appliances at AT&T-served branches
  • Telemetry links for infrastructure monitoring equipment

Questions buyers ask

Is this modem locked to AT&T?

It is configured for AT&T service. For Verizon deployments choose the SKSC4MVZW-R variant, and for carrier flexibility choose SKSC4A-UR.

What speeds should I expect?

LTE Cat 4 supports downlink speeds up to the 150 Mbps class; real-world throughput depends on signal conditions and network load at the site.

What does the 3G fallback provide?

Where LTE coverage is unavailable, the modem can fall back to 3G service, keeping low-bandwidth telemetry and management traffic online.

What warranty applies?

The Skyus SC carries a one-year hardware warranty, and fleets are supported through Inseego's IoT Connect management platform.
