Hungary: infrastructure
Four operating reactors built between 1982 and 1987 form the Paks Nuclear Power Plant, and nuclear is the main domestic energy source, with almost half of Hungary's energy imported as of 2024.

Short answer. An explosion proof cell phone for Hungary cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
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.

More about Hungary that matters for portable equipment
Hungary: who works there
MOL is active in exploration and production, refining, distribution, petrochemicals, power generation, trading and retail, with operations in over 30 countries and 2,400 service stations in ten countries as of 2025.
Hungary: industry on the ground
MOL's Danube Refinery at Százhalombatta started up in 1965 and has a capacity of about 8.1 million tonnes a year, making it one of the largest refineries in Central and Eastern Europe.
Hungary: industry on the ground
The Matra power plant, the last coal electricity producer, supplied about 9% of Hungary's electricity in 2020 and was served by coal mines in Visonta and Bükkábrány, with a gas combined-cycle replacement planned.
The term · explosion proof
What “explosion proof” means for a smartphone
“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 Hungary. In Hungary explosion-proof is a common phrase, but refinery units, polymer plants and pharmaceutical solvent suites use different protection concepts. Flameproof Ex d suits some fixed equipment, while a handset moving between rooms is better served by intrinsic safety. The IS-04Z1 is designed around intrinsic safety for that reason.

Questions · Hungary
Frequently asked questions
Can we buy an explosion proof cell phone in Hungary 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 explosion proof cell phone in Hungary 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
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.
Which sites in Hungary does this cover?
The market guide for Hungary covers Százhalombatta, Tiszaújváros, Kazincbarcika, Dorog, among others. Site-level pages are linked below.
How will SAMS supply Hungary?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
How does Hungary's winter weather affect Ex handheld devices?
Continental winters can bring sub-zero temperatures, which reduce battery capacity. Check the lowest rated ambient temperature on the certificate and whether touch input works with gloves. Plan spare batteries and warm storage for outdoor work at refineries and pipeline stations.
Which Hungarian companies run the main classified-area sites?
MOL is the largest integrated oil, gas and petrochemical group, and the Paks plant and gas network operators also have hazardous areas. Each company runs its own supplier approval, so contact its procurement and HSE teams for current device and contractor requirements.
Can one device cover both a refinery and a pharmaceutical plant?
Gas groups, dust and temperature needs differ between a refinery and a solvent suite. A device would need a marking that suits each classification. Check each plant's zone documents, since the answer depends on the operator's classification rather than the device alone.
