Industrial Mobile Phone in Surabaya
Surabaya is the capital of East Java and home to Tanjung Perak, Indonesia's second-largest port. The Surabaya Industrial Estate Rungkut and neighbouring Gresik, with a fertiliser plant and cement works, hold the chemical, fuel and process areas where Zone 1 and Zone 21 equipment applies. This page explains what to look for in an industrial mobile phone for Surabaya and the Gresik industrial area, and where the IS-04Z1 stands against that list today.

The term · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Surabaya and the Gresik industrial area. Surabaya has many plants of varied size, from large operators such as Petrokimia Gresik to the estate's roughly 300 companies, so fleets range widely. MDM or EMM enrolment, contractor rules and safe-area charging should be agreed with each site.

Questions · Surabaya
Frequently asked questions
Can we buy an industrial mobile phone in Surabaya 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 industrial mobile phone in Surabaya cost?
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.
Is the IS-04Z1 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
Which areas at Surabaya and the Gresik industrial area would use it?
Likely candidates are port fuel and chemical handling, fertiliser and chemical plants, cement plant dust areas, industrial estate chemical plants. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
How do I move equipment between Surabaya and Madura or other East Java sites?
The Suramadu Bridge links Surabaya and Madura by road, and Tanjung Perak serves sea freight to eastern Indonesia. Allow time for customs clearance and for any site gate checks on electronic devices at plants and terminals.
Why is Surabaya a useful base for marine and shipyard work?
It has Indonesia's second-busiest seaport, a large shipyard and naval facilities, plus freight forwarders and customs brokers. Marine work typically involves tank entry and hot work, so confirm each yard's permit rules for portable electronic devices.
Can one handset serve both chemical plants and cement works around Surabaya?
Not necessarily. Chemical and fuel areas are gas hazards, while cement works are dust areas, and each needs a suitable marking. The IS-04Z1 target marking covers gas only. Check each area's classification with the operator.
