Nigeria: projects and investment
An expansion announced in October 2025 would lift the Dangote refinery to 1.4 million barrels a day, with completion estimated for 2029.
Nigeria: rules and approvals
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.
Nigeria: background
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.
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 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.

Specifying an Ex-proof mobile phone for Nigeria
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 · Nigeria
Frequently asked questions
Can we buy an Ex-proof mobile phone in Nigeria today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an Ex-proof mobile phone in Nigeria 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 Nigeria does this cover?
The market guide for Nigeria covers Port Harcourt, Rivers State, Warri and Escravos, Bonny Island, Lekki Free Zone, Lagos, 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.
What approval does a mobile phone need in Nigeria?
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.
Where does hazardous-area work concentrate in Nigeria?
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.
Does the device work where coverage varies by kilometre?
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.
