Large industrial base
The Sohar Aluminium smelter has a capacity of roughly 390,000 tonnes a year with its own power plant, so construction and maintenance contractors are present.

Ex-Proof Mobile Phone in Sohar
SOHAR Port is described as handling more than one million tonnes of sea cargo a week and around 3,500 ship calls a year, so jetty and yard traffic is continuous. Refining, metals and iron-ore processing are clustered there, which creates Zone 1 and Zone 21 work in process plants and bulk-liquid storage. If you are specifying an Ex-proof mobile phone for Sohar, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Local conditions · Sohar
Site conditions at Sohar: what wears and what limits equipment
Hot climate
Summers are very hot on this stretch of the Gulf of Oman coast, so handset heat tolerance matters for outdoor rounds.
Field notes · Sohar
More about Sohar that matters for portable equipment
Sohar: rules and approvals
Oman's Telecommunications Regulatory Authority follows EU-style type-approval procedures for radio equipment and issues a TRA label; a self-declaration route has also been introduced, so confirm the current path.
Sohar: climate and equipment wear
Sohar has a hot desert climate with very hot summers and mild winters; rain is scarce, with more than half the annual total falling in February, so summer heat is the main stress.
Sohar: industry on the ground
The port and free zone were planned around three industrial clusters, logistics, metals and petrochemicals, and a food cluster with an agro-bulk terminal was added later, giving mixed gas and dust hazards.
Sohar: geography and layout
The port lies in Liwa wilaya, in the centre of Al Batinah North Governorate, on the Gulf of Oman side of the Strait of Hormuz, so ships reach it without passing through the strait.
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 Sohar. For a refinery unit, port liquid bulk berth or fuel and chemical storage, a marking check reads zone, gas group and temperature class on the label and compares each with the operator's records. Fuels and chemicals span several gas groups, so the target marking II 2 G Ex ib IIC T4 is compared with the site data.

Questions · Sohar
Frequently asked questions
Can we buy an Ex-proof mobile phone in Sohar 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 Sohar cost?
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.
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 areas at Sohar would use it?
Likely candidates are refinery process units, port liquid bulk handling, fuel and chemical storage, industrial plant utilities. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Does heat at Sohar affect handset choice for outdoor rounds?
Summers are very hot there, so check the datasheet operating and charging temperature range, keep devices out of direct sun on jetties, and plan battery swaps for long shifts. Ask the plant operator whether it sets its own temperature limit for portable devices.
Can UAE-based service teams reach Sohar easily?
Sohar has road links towards the UAE, and the Hafeet Rail corridor is being built to join the port to the UAE network. For hazardous areas, border and site-access paperwork still sits with the client, so allow time for permits and inductions.
Do I need separate approvals for each Sohar operator?
Each operator at the port runs its own supplier approval and permit system, so one approval does not cover all. Ask the refinery, port company or industrial plant what it requires for portable devices. Confirm with the operator.
