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 Pekanbaru and the Rokan block, Riau. Procurement follows Pertamina group processes since the block passed from Chevron's Indonesian subsidiary. A fleet would need MDM or EMM enrolment, contractor and operator ownership rules and safe-area charging. Coverage across a large block should be tested before rollout.

Questions · Pekanbaru Oil Field
Frequently asked questions
Can we buy an industrial mobile phone in Pekanbaru Oil Field 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 industrial mobile phone in Pekanbaru Oil Field 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 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 Pekanbaru and the Rokan block, Riau would use it?
Likely candidates are gathering stations, wellheads and flowlines, oil treatment and storage, steam generation and power facilities. 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.
Why does steamflood production matter for equipment used at Duri?
Steamflood means hot steam lines and wells operate close to oil and gas handling, so surface temperatures can be higher than at conventional wells. Handheld devices should respect the site's temperature limits and classification, so ask the operator for its rules on portable electronics.
Which company operates the large oil fields around Pekanbaru today?
The Rokan block, including the Minas and Duri fields, has been run by Pertamina Hulu Rokan since August 2021. Contractors and suppliers typically register through Pertamina's vendor processes and follow the site's own induction and permit rules, so confirm current requirements.
Who approves suppliers for the Rokan block?
Suppliers are normally approved by the operator and its contractors, following Pertamina group processes since the 2021 operator change. Ask PT Pertamina Hulu Rokan about current registration requirements before offering any equipment. Confirm with the site operator.
