When you're deploying mobile devices in hazardous areas—whether that's an oil refinery, a chemical plant, or an upstream drilling operation—the conversation usually starts and ends with safety certifications. Class I Division 1. Zone 1. Intrinsically safe. And rightly so.

But there's another layer of approval that often gets overlooked, one that's just as critical to your day-to-day operations: carrier approval.

We're proud to offer i.safe MOBILE's IS540.x smartphone portfolio with full AT&T and Verizon carrier approvals plus the IS940.x and IS945.x tablet platforms with Verizon approvals. Here's why that matters more than you might think.

Why Carrier Approval Matters in Hazardous Environments

In a standard office environment, using an uncertified or carrier unapproved device is an inconvenience. In a hazardous area, it can be a serious liability.

Carrier-approved devices have been tested and validated to operate correctly on the network infrastructure of that carrier. That means:

• Reliable connectivity: Approved devices are optimized to maintain stable LTE/5G connections, reducing dropped calls, data interruptions, and failed push-to-talk sessions at the exact moments your team needs to communicate.
• Network security: Carrier approval ensures the device meets the security protocols required to operate on enterprise-grade networks. This matters enormously in regulated industries where data integrity and secure communications are non-negotiable.
• SIM interoperability: Unapproved devices can experience SIM lock issues, band incompatibilities, or network rejection—none of which you want to troubleshoot on a well pad 40 miles from town.
• Compliance and insurance: Many operators, EPC contractors, and facility owners require carrier-approved devices as part of their IT and HSE procurement policies. Having approval documentation on hand simplifies audits and vendor qualification processes.
• Enterprise support: AT&T and Verizon's enterprise teams can fully support approved devices—remote provisioning, MDM integration, and dedicated business account management all become straightforward.

In short: hazardous area certification keeps your people safe. Carrier approval keeps your operations running.

Our Smartphone Portfolio: Certified for the Hazardous Area, Approved for the Network

IS540.x Smartphone Series — AT&T and Verizon Approved

The IS540.x series represents i.safe MOBILE's flagship Android-based smartphone lineup built specifically for classified locations. The series carry AT&T and Verizon approvals and are available in three variants to match your site classification:

• Class I Division 1 / Zone 1 — For the most demanding environments where explosive atmospheres are present continuously or for long periods. Intrinsically safe design, fully certified for use in the harshest upstream oil and gas locations.
• Class I Division 2 / Zone 2 — For areas where flammable gases or vapors are present only under abnormal conditions. A practical, cost-effective solution for the majority of petrochemical and refining environments.
• Rugged General Purpose — For non-classified areas where you still need the durability, reliability, and enterprise features of a purpose-built industrial device—without the hazardous area premium.

All three variants share the same familiar form factor, operating system, and software ecosystem, which simplifies device management, training, and spare parts inventory across your fleet.

IS940.x and IS945.x Tablet Platforms — Verizon Approved

The IS940.x and IS945.x are i.safe MOBILE's flagship tablet platforms, bringing enhanced processing power, camera capability, and display quality to the hazardous area. With the latest Android OS running on the IS940.x range and Windows 11 LTSC running on the IS945.x series, we are able to offer the right device for any application.  The two ranges have Verizon approval and are similarly available across three variants:

• Class I Division 1 / Zone 1 — Maximum protection for the most hazardous classified locations.
• Class I Division 2 / Zone 2 — Certified for use in areas where explosive atmospheres occur only abnormally.
• Rugged General Purpose — Enterprise-grade rugged performance for non-classified areas and support zones.

One Ecosystem. Every Area. Every Network.

Having a unified device ecosystem across your enterprise — from the Zone 1 wellhead to the general-purpose control room—offers real operational advantages. Standardized MDM profiles, consistent user training, shared accessories, and simplified procurement all contribute to lower total cost of ownership.

Add AT&T and Verizon carrier approval into the mix, and you have a portfolio that meets procurement, IT, HSE, and operations requirements in a single conversation.

Whether you're building out a new facility, refreshing aging device fleets, or responding to a carrier network transition, Exloc can help you match the right device to the right zone —with the right carrier behind it.
