Tropical weather
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.
Carmen was granted port status in 1841 because of its maritime trade and was made a city in 1856; earlier centuries saw it used as a port for repairing ships. Pemex operates a maritime terminal here, so classified-area work is at port facilities and offshore platforms supplied from the island. This page explains what to look for in an Ex-proof smartphone for Ciudad del Carmen, and where the IS-04Z1 stands against that list today.
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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Ciudad del Carmen: Marine terminal and storage, Offshore production platforms, Supply-vessel and crew-change bases | Classified by the site operator |

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.
The companies on site and the hazardous-area types a handset is likely to meet there.
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 Sonda de Campeche, with the Cantarell field, lies roughly 85 km offshore, so many staff here work rotations on platforms and vessels.
Arrival of specialised oil staff doubled the Carmen municipality's population between 1970 and 1980 to 144,684, and the city moved from a shrimping economy, begun in the 1940s, to one that relies on oil.
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.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Ciudad del Carmen. For a platform, marine terminal or supply base, a marking check reads zone, gas group and temperature class on the label and compares each with what the operator has classified. Offshore hydrocarbons are typically in IIA or IIB, and a IIC marking such as the IS-04Z1 target would be read against that, not assumed.
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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
