Island logistics
The city sits on an island in the Laguna de Terminos, linked to the mainland by the 3.9 km Zacatal Bridge.
Ciudad del Carmen is a port city on Isla del Carmen in Campeche, and the main shore base for offshore oil activity in the Sonda de Campeche. The Ku-Maloob-Zaap area lies about 107 km north-east of Ciudad del Carmen and was described as Mexico's largest oil producer, so offshore activity is centred north-east of the city. If you are specifying a hazardous area smartphone for Ciudad del Carmen, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Ciudad del Carmen: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Ciudad del Carmen. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
The city sits on an island in the Laguna de Terminos, linked to the mainland by the 3.9 km Zacatal Bridge.
There is a dry season from January to May and heavy rain later in the year; Gulf hurricane season can disrupt crew changes and sea transport.
The Universidad Autonoma del Carmen (UNACAR) is the main university in Ciudad del Carmen, providing a local base of technical graduates for port and marine activity.
The Puente del Zacatal, built in 1994, is one of the longest bridges in Latin America and is a key road link for the island city.
The city lies on Isla del Carmen at the western edge of the Yucatan Peninsula and has been part of the state of Campeche since 1863.
Pemex's exploration of the Campeche Basin in the early 1970s led to the Cantarell field, about 70 km from Ciudad del Carmen, which supplied 63.2 per cent of Mexico's crude at its 2004 peak before declining.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Ciudad del Carmen. Classified areas for Ciudad del Carmen workers include the Pemex marine terminal and storage, offshore production platforms and supply-vessel and crew-change bases. Pemex or its contractors, not SAMS, classify these areas. Ask for the relevant zone documentation before specifying a device, and note that offshore decks and onshore bases may differ.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Likely candidates are marine terminal and storage, offshore production platforms, supply-vessel and crew-change bases. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Typically by helicopter or supply vessel, depending on the operator. Transfers are weather dependent, and carry-on rules for powered devices vary by operator and aircraft. Confirm requirements with the operator's logistics team.
It is commonly used as a shore base for operations in the southern Gulf of Mexico, and Cantarell-area offshore assets are described as lying tens of nautical miles offshore. Confirm which base, operator and transport your project uses.
Gulf hurricane season can disrupt crew changes and sea transport, and the city sits on an island linked to the mainland by the Zacatal Bridge. Allow extra lead time and agree shipping routes with your contractor or Pemex. Confirm any restrictions with the site operator.
