Nigeria: rules and approvals
NCC type approval standards are based on international work from IEC and CISPR, CENELEC and ETSI, and the commission publishes lists of approved handsets and approved equipment.
A Zone 1 / Zone 21 smartphone for crews on Niger Delta flow stations, deepwater FPSOs, export terminals and the refining complexes at Lekki and Eleme. If you are specifying an Ex-proof cell phone for Nigeria, 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 Nigeria: 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 | Nigeria: Port Harcourt, Rivers State, Warri and Escravos, Bonny Island | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Nigeria. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The classified areas, operators and sites below are the ones covered in the SAMS Nigeria market guide.
NCC type approval standards are based on international work from IEC and CISPR, CENELEC and ETSI, and the commission publishes lists of approved handsets and approved equipment.
An expansion announced in October 2025 would lift the Dangote refinery to 1.4 million barrels a day, with completion estimated for 2029.
The Nigerian Communications Commission enforces type approval under the Nigerian Communications Act 2003, and mobile phones and wireless adapters must conform to applicable standards before being brought into Nigeria.
The Niger Delta was once called the Oil Rivers because it was a major producer of palm oil, and it is now a petroleum-rich region with a very dense population.
“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 Nigeria. A marking check in Nigeria compares II 2 G Ex ib IIC T4 with the area drawing. Nigerian hydrocarbon service is typically Group IIA and IIB, so an IIC marking target covers those. Offshore and onshore facilities may also include dust or other hazards that the operator classifies, and the T4 ambient range should be confirmed.
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.

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.
The Nigerian Communications Commission requires type approval for telecom equipment, including customer devices such as mobile phones, and publishes approved handset and equipment lists. Approval is based on international standards. Confirm the current application route and fees with the NCC or an authorised agent before importing.
Typically in the Niger Delta's onshore and shallow-water oil and gas facilities, flow stations and terminals, and in refineries and LNG and fertiliser plants in the south, including the Lekki refinery near Lagos. Each operator issues its own area classification, so request it before choosing equipment.
Coverage depends on carrier and site, not on the handset. The IS-04Z1 is designed to connect over cellular and plant Wi-Fi, but remote Delta locations and offshore units may have weak signal. Confirm with the operator what network will be available at each site before relying on it.
