IECEx Cell Phone in Indonesia
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 an IECEx cell phone for Indonesia, and where the IS-04Z1 stands against that list today.

WhereIndonesia
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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Field notes · Indonesia
More about Indonesia that matters for portable equipment
Indonesia: infrastructure
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.
Indonesia: rules and approvals
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.
Indonesia: rules and approvals
Technical requirements for 5G devices follow Perdirgen No. 5/2021, so 5G-capable phones are tested against that rule as part of SDPPI certification.
The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Indonesia. Indonesian refineries, LNG plants and fields work with international operators and EPCs, for which IECEx is the common reference. A certificate of conformity names the equipment, and its schedule of conditions sets the conditions of use. IECEx certification for the IS-04Z1 is in progress; local type approval and TKDN work is also in progress.

Specifying an IECEx cell phone for Indonesia
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 · Indonesia
Frequently asked questions
Can we buy an IECEx cell phone in Indonesia today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an IECEx cell phone in Indonesia cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which sites in Indonesia does this cover?
The market guide for Indonesia covers Cilacap, Central Java, Balikpapan, East Kalimantan, Dumai, Riau, Balongan, West Java, 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 conditions should devices handle at Indonesian industrial sites?
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.
How does Indonesia's island geography affect equipment logistics?
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.
How would a remote island site get support?
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.
