Angola: geography and layout
Cabinda is an exclave province of Angola, separated from the rest of the country by territory of the Democratic Republic of the Congo, which affects how people and equipment are moved there.
A Zone 1 / Zone 21 smartphone for crews on Angola's deepwater FPSOs, the Cabinda and Soyo onshore facilities, Angola LNG and the Luanda refinery. If you are specifying an Ex-proof mobile phone for Angola, 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 Angola: 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. 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 | Angola: Luanda, Soyo, Zaire province, Cabinda and Malongo | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Angola. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS Angola market guide.
Cabinda is an exclave province of Angola, separated from the rest of the country by territory of the Democratic Republic of the Congo, which affects how people and equipment are moved there.
Portuguese is Angola's official language, so permits, manuals and safety notices for local crews are normally expected in Portuguese.
The Instituto Angolano das Comunicações, INACOM, is the telecom regulator whose homologation is needed for wireless and telecom equipment sold in Angola.
Angola LNG Limited is owned by Sonangol, Chevron, TotalEnergies and Azule Energy, so the Soyo site combines several shareholders' operating practices.
“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 Angola. At Soyo and on the FPSOs, hydrocarbon service is typically Group IIA and IIB. A marking check would look for the gas group, the T class and the ambient range, reading the target of II 2 G Ex ib IIC T4 against the area drawings. Because the target is IIC, one specification would run from a process deck to the LNG jetty.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
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.

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.
Large sites such as Angola LNG have several shareholders and an operating company that sets site HSE rules, which may follow one partner's standards. Confirm which standards and approved-equipment lists the operating company applies before you ship devices to Angola.
A single-train LNG plant typically has liquefaction, gas treatment, propane and butane storage, condensate handling and marine loading areas, all of which are normally classified as hazardous. The operator issues the zone drawings, so request them with the gas group and temperature class before choosing equipment.
It is designed for Zone 1 and Zone 21 duty, with a target marking of II 2 G Ex ib IIC T4, but certification is in progress and no certificate has been issued. Offshore use would depend on the operator's own equipment approval and the schedule of conditions. Confirm with the FPSO operator before any deck use.
