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.

More about Angola that matters for portable equipment
Angola: people and language
Portuguese is Angola's official language, so permits, manuals and safety notices for local crews are normally expected in Portuguese.
Angola: rules and approvals
The Instituto Angolano das Comunicações, INACOM, is the telecom regulator whose homologation is needed for wireless and telecom equipment sold in Angola.
Angola: who works there
Angola LNG Limited is owned by Sonangol, Chevron, TotalEnergies and Azule Energy, so the Soyo site combines several shareholders' operating practices.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“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.

Specifying an Ex-proof cell phone for Angola
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Angola
Frequently asked questions
Can we buy an Ex-proof cell phone in Angola today?
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.
What does an Ex-proof cell phone in Angola cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
What Ex marking will the IS-04Z1 carry?
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.
Which sites in Angola does this cover?
The market guide for Angola covers Luanda, Soyo, Zaire province, Cabinda and Malongo, Lobito, Benguela, among others. Site-level pages are linked below.
Is intrinsically safe the same as explosion proof?
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.
How do shareholder differences affect equipment approval at Angolan oil and gas sites?
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.
What hazardous areas are typical at the Soyo LNG site?
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.
Can the phone be used offshore on a deepwater FPSO?
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.
