Pakistan: logistics and access
Port Qasim near Karachi handles about 35% of Pakistan's cargo, roughly 17 million tonnes a year, and with Karachi port carries almost 90% of external trade, so most imported equipment clears through these two ports.
A Zone 1 / Zone 21 smartphone for crews on the gas fields of Sindh and Balochistan, the refineries at Karachi, Attock and Mahmood Kot, the LNG terminals at Port Qasim and the fertiliser plants. If you are specifying an explosion proof cell phone for Pakistan, 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 Pakistan: 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Pakistan. 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 Pakistan market guide.
Port Qasim near Karachi handles about 35% of Pakistan's cargo, roughly 17 million tonnes a year, and with Karachi port carries almost 90% of external trade, so most imported equipment clears through these two ports.
Five main refineries have a combined capacity of about 450,000 barrels a day, producing diesel, motor gasoline, furnace oil, jet fuel, kerosene, LPG and naphtha, so product storage and loading areas are widespread.
The Thar coalfield in Sindh covers over 9,000 square kilometres and holds an estimated 200 billion tonnes of lignite; the Sindh Engro Coal Mining Company is the principal mining operator there.
The Toot oil field in Punjab, about 135 km south-west of Islamabad, saw its first well in 1964 and commercial production from 1967, showing that upstream work also happens in the inland north.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Pakistan. Gas crews at Sui and Mari say explosion proof for anything used near hydrocarbons, but the concepts differ. Flameproof Ex d suits fixed equipment, while the IS-04Z1 uses intrinsic safety, Ex ib. That is the concept that suits a handset carried through a wellsite, a compressor station or a refinery unit at Mahmood Kot or Morgah.
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.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
The market guide for Pakistan covers Sui, Balochistan, Daharki and Ghotki, Sindh, Port Qasim, Karachi, Korangi, Karachi, among others. Site-level pages are linked below.
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.
Examples include the Sui gas area in Balochistan, the Toot field in Punjab, Lower Sindh gas fields and the five main refineries. Which areas are classified, and to what zone, is decided by each operator, so ask for its hazardous-area drawings.
Operators commonly ask for recognised international certification such as IECEx or ATEX against IEC 60079, but acceptance is set site by site. Request the operator's equipment approval procedure and provide certificates, marking details and manufacturer instructions with your submission.
Coverage depends on the carrier, not the handset. The device is designed to fall back to plant Wi-Fi where the signal is thin, but that depends on the site's network. Confirm with the field operator what connectivity is available before relying on it for work orders.
