The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Al-Ahsa (Hofuf). Associated gas handling and wellsites suggest Zone 1 gas areas, so a marking check reads the zone, gas group and temperature class from the operator's classification. Fuels and gas are often in the lower groups, but the operator decides. The IS-04Z1 target marking is II 2 G Ex ib IIC T4.

Distributing the IS-04Z1 in Al Ahsa
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Al-Ahsa (Hofuf) yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Al-Ahsa (Hofuf).
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.

Questions · Al Ahsa
Frequently asked questions
Can we buy an Ex-proof smartphone in Al Ahsa 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 Ex-proof smartphone in Al Ahsa 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Al-Ahsa (Hofuf) would use it?
Likely candidates are oil wellsites and gathering, associated gas handling, water injection facilities, pipeline pump stations. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Al-Ahsa (Hofuf)?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Al-Ahsa (Hofuf).
Are Al-Ahsa oil facilities close to towns and farmland?
Often yes. The Al-Ahsa oasis and Hofuf sit on the eastern flank of the Ghawar field, so wellsites, gas handling and pipelines can be near settlements and agricultural land. Follow the operator's access and gate procedures rather than assuming open public roads lead to sites.
Why are Ghawar facilities spread over such a wide area?
Ghawar is divided into five production areas running north to south, and the governorate covers about 375,000 square km. Teams often travel long distances between sites, so plan device charging, spare batteries and offline documentation rather than relying on constant connectivity.
Will a phone work across such a large field?
Ghawar is divided into several zones and sites are widely spread, so coverage and travel time vary. Ask the site operator about network coverage and whether devices need to work offline. Device management through EMM or MDM should be planned around that, and handsets are best charged at a safe base.
