Indonesia: background
Pertamina was created in August 1968 by merging Pertamin, founded in 1961, and Permina, founded in 1957 from nationalised Shell assets, and it is headquartered in Jakarta.
A Zone 1 and Zone 21 handset for Indonesian operators, mechanics, inspectors and contractor crews working across an archipelago where the nearest replacement device is often a flight away. This page explains what to look for in a hazardous area smartphone for Indonesia, 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 Indonesia: 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Indonesia. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The main operators, industrial areas and sites that the SAMS Indonesia market guide covers.
Pertamina was created in August 1968 by merging Pertamin, founded in 1961, and Permina, founded in 1957 from nationalised Shell assets, and it is headquartered in Jakarta.
Pertamina operates six oil refineries with a combined capacity of around 1 million barrels a day, as of 2013, and has not built a new refinery since Balongan opened in West Java in the mid-1990s.
Radio and telecom equipment certification by SDPPI is compulsory in Indonesia, with a three-year validity, local testing and a local representative required, and a marking requirement.
Technical requirements for 5G devices follow Perdirgen No. 5/2021, so 5G-capable phones are tested against that rule as part of SDPPI certification.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Indonesia. Indonesian classified areas include Pertamina refineries, the Rokan block gathering stations, LNG trains at Bontang and Tangguh, the Cepu field, crackers at Cilegon and fertiliser plants. The operator classifies each area, not SAMS. The IS-04Z1 is designed for Zone 1 and Zone 21.
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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.

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.
Tropical sites typically combine heat, high humidity, heavy rain and, near the coast, salt air, so check ingress protection, corrosion resistance and operating temperature range. Confirm site-specific requirements with the operator, including any area classification and approved-device lists.
With thousands of islands, many sites are reached by sea or air, and delays are common. Plan extra lead time and spares for devices, chargers and batteries, and ask the operator or contractor about shipping, customs and site approval rules for each island location.
Supply after certification would be through authorised distributors, and none has been appointed yet. For remote sites, ask about spares, replacement time and training before purchase, and agree the logistics route with the operator. Trial units can be tested to check connectivity and battery use first.
