Pakistan: industry on the ground
Oil production was confined to Punjab until 1981, when a company found the first field in Lower Sindh; by 1998-99 the Lower Sindh gas fields produced more oil than Punjab.
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. This page explains what to look for in an intrinsically safe smartphone for Pakistan, and where the IS-04Z1 stands against that list today.
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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. 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.
The classified areas, operators and sites below are the ones covered in the SAMS Pakistan market guide.
Oil production was confined to Punjab until 1981, when a company found the first field in Lower Sindh; by 1998-99 the Lower Sindh gas fields produced more oil than Punjab.
Domestic refining typically meets about 60% of Pakistan's diesel, 30% of motor gasoline and all jet fuel demand, so the rest arrives as imports through port terminals.
The Pakistan Telecommunication Authority, headquartered in Islamabad, regulates telecom systems and radio spectrum under the 1996 Telecommunication (Re-organization) Act, with zonal offices in Karachi, Lahore, Gwadar, Quetta, Peshawar and other cities.
Pakistan's first gas field was found near Sui in Balochistan in 1952, and the Sui area remains a name associated with the country's gas supply and upstream classified-area work.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Pakistan. Rounds at a wellsite, a compressor station, a Port Qasim LNG terminal or a fertiliser plant make many entries into classified ground. An intrinsically safe handheld lets an operator photograph, log and scan equipment on foot. Because there is no safe-area socket mid shift, the battery must carry a working day.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is 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.
Allow for import clearance, courier or freight time and any PTA rules for radio-equipped devices, then keep spare batteries and chargers on site. Large refineries typically run contractor induction before work, so agree device approval at the start of planning.
The Pakistan Telecommunication Authority, set up in 1996, regulates telecom systems and spectrum, with zonal offices in cities including Karachi, Lahore and Quetta. Device import and approval rules change over time, so check current PTA requirements with your importer before shipping.
Summer ambients there can pass 45 degrees. The certified ambient range is stated on the certificate and will be published when issued, so check it against your site maximum before planning summer use. IP68 and a rugged build help with dust but do not extend the certified range.
