The IS-04Z1 is an Ex mobile phone for people working inside classified areas at Mexican refineries, offshore platforms, petrochemical plants and fuel terminals. It is pre-launch: the hazardous area certification program and the homologación every radio product needs here are both in progress for a Q4 2026 launch. Often searched for as an “explosion proof phone”, the IS-04Z1 uses intrinsic safety as its protection concept.

Qualcomm SnapdragonThe work runs along two coasts and one central corridor: refining and petrochemicals on the Gulf, production offshore Campeche, and inland refining from Tula to the Bajío and the northeast.
Operators and contractors such as Pemex, CFE and Braskem Idesa need an explosion proof mobile phone they can carry into classified areas at Dos Bocas, Tabasco, Bay of Campeche and Ciudad del Carmen. The IS-04Z1 is designed for Zone 1 and Zone 21 duty there.
Six points come up whenever a Mexican plant looks seriously at a handset for a classified area.
For evaluators in Mexico, the IS-04Z1 explosion proof mobile phone is designed around these points: The Division system, written in Spanish; Gulf coast heat and salt air; Dust areas that get left out; Offshore rotations and boat transfers; Spanish from the first screen; Contractor fleets that turn over fast.
NOM-001-SEDE follows the American structure: Article 500 classifies áreas peligrosas as Clase I, II and III with Divisiones 1 and 2. The device is designed for that duty and for Zone 1, so one specification answers a drawing written either way.
Altamira, Coatzacoalcos, Dos Bocas and a Campeche deck combine high humidity with salt-laden air and long hours outdoors. IP68 sealing and rugged build cover the physical side, and T4 is reconciled with the drawing.
Coke handling at a refinery, sulfur, cement, grain and mineral processing are combustible dust locations where a gas-only fleet stops. The Zone 21 design target keeps one device valid across both.
A Campeche platform is reached by helicopter or crew boat, and a failed handset waits for the next one. A 4,000 mAh battery, a Snapdragon octa-core platform, four-constellation GNSS and platform Wi-Fi suit that pattern.
Android 16 runs the interface in Spanish, and Spanish documentation is part of the launch package. It matters for hazard communication under NOM-018-STPS and for training records an inspector expects in the working language.
Refinery and offshore scopes are staffed by crews that change with the contract. EMM and MDM enrollment locks a device to an approved app set and wipes it at demobilization, so a loaned fleet stays accounted for.
Mexican plants classify hazardous areas the way the American code does, so the specification arrives as Clase I División 1. What closes the file is the dictamen from the unidad de verificación, and in hydrocarbons the requirements ASEA enforces above it.
The standard your electrical designer works from is NOM-001-SEDE, the Mexican official standard for electrical installations, and it is compulsory. Article 500 classifies áreas peligrosas as Clase I for flammable gases and vapours, Clase II for combustible dust and Clase III for fibres, each with Divisiones 1 and 2, and the articles after it set what equipment may be used there. The structure mirrors the American code, which is why a Mexican site asks for Clase I División 1 even where the plant was engineered to an international standard and the same area would be called Zone 1. Conformity is not self-declared: an installation in a classified area is assessed by a unidad de verificación accredited for the standard, and the dictamen it issues is what the plant produces when inspected.
Three further obligations shape the purchase. In hydrocarbons the safety requirements sit with ASEA, the Agencia Nacional de Seguridad Industrial y de Protección al Medio Ambiente del Sector Hidrocarburos, which regulates operations from wellhead to retail. On the workplace side NOM-005-STPS governs work with hazardous chemical substances and NOM-018-STPS governs hazard identification and communication, and together they are where a site records what may be carried past a boundary sign. On the radio side, no telecommunications product may be sold or connected without homologación, and that responsibility changed hands recently: the telecommunications law of 2025 dissolved the IFT and moved type approval to the Comisión Reguladora de Telecomunicaciones in October 2025, while certificates already issued and the IFT number on existing labels remain valid.
Typical Zone 1 and Zone 21 duty for the IS-04Z1 explosion proof mobile phone in Mexico includes: Ramp-up and commissioning at Dos Bocas; Deck rounds in the Bay of Campeche; Loading and tank farm work at Altamira; Paro de mantenimiento at an inland refinery.
The Olmeca refinery has been building output through 2026 with commissioning crews still working alongside operations. That is the hardest information environment a plant ever has, and a handset that works inside the classified area lets a supervisor confirm a line-up from there.
On a Ku-Maloob-Zaap complex the walk from a job to the control room is the tax on every permit question, and the next boat is hours away. An Ex phone lets the technician photograph an isolation and close the permit at the work front.
Manifolds, loading arms and tank tops at a petrochemical port put crews in vapour with a vessel schedule that will not wait. One device that takes a washdown, holds a call from the berth and photographs a damaged coupling saves a trip.
A shutdown at Tula, Salamanca or Cadereyta fills a classified unit with contract crews on rotating permits. When each crew carries a handset enrolled in the site system, the job pack, the permit and the photographic record stay in one place.
Nothing enters a classified area before certification is complete, so the pre-launch conversation is about evidence, an evaluation and the route into the country.
Tell us the clase, división and group from the drawing, or the zone if the plant was engineered to the international system, plus the number of users and who carries the devices.
You receive the technical datasheet and a written schedule of every certification being pursued, hazardous area and radio, with the status of each. Nothing is complete before the certificate exists.
Evaluation units go to sites that will put them into real conditions, offshore or in a unit. Pilot places are being allocated across refining, offshore and petrochemicals.
Supply normally runs through a Mexican partner handling import, the homologation file and the documentation your unidad de verificación will want. Direct supply is available where a customer prefers it.
Send your site, zone and gas group, and we will answer for your plant rather than in general.
Ask about Mexico →No. It is designed for Clase I División 1 and Zone 1 duty and certification is in progress ahead of the Q4 2026 launch. Until the certificate exists no Mexican site should treat it as suitable for a classified area.
Partly, and it is worth settling early. NOM-001-SEDE classifies areas the same way, so the Clase I División 1 description applies, but the acceptance decision is made by the unidad de verificación. Agree in advance which certificates go into the dictamen file.
Buyers ask for a flameproof or a prueba de explosión phone and mean any handset usable in a classified area, but the concepts differ. Flameproof, Ex d, contains an ignition inside a heavy enclosure. A handheld takes the seguridad intrínseca route, Ex ib.
Yes, and the number appears on the product. Type approval moved from the IFT to the Comisión Reguladora de Telecomunicaciones in October 2025 under the new telecommunications law, while certificates the IFT already issued remain valid, so check which body issued the one you are shown.
Android 16 runs the interface in Spanish, and Spanish documentation is part of the launch package. Ask for the manual and label text with the certification schedule so your NOM-018-STPS material is ready alongside the rollout.
There is no list price before certification is complete. Pre-launch pricing is given on request once we know fleet size, configuration and whether supply runs through a Mexican distributor or direct, because the import route changes the landed figure.
It is designed for that duty: Clase I División 1 and Zone 1 gas areas, IP68 and rugged build, and platform Wi-Fi where cellular coverage stops. Confirm the operator policy and the ASEA requirements alongside the schedule.
Yes. It is aimed at Zone 21 as well as Zone 1, which covers the coke handling, sulfur, cement, grain and mineral processing a gas-only specification leaves out. The dust marking is published with the certificate.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Mexico. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
SAMS Mobile is appointing Mexican distribution ahead of the Q4 2026 launch, with priority on partners already supplying industrial safety and electrical equipment into refining, offshore Campeche, the Isthmus petrochemical corridor and the northern industrial belt.
