Ex-Proof Smartphone Distributor in United Kingdom
The IS-04Z1 is an intrinsically safe Android smartphone designed for Zone 1 and Zone 21 work, from a North Sea deck to a gas governor kiosk at the end of a street. Since 1 October 2024 CE marking has been recognised in Great Britain without an end date, so ATEX-certified products can be sold there without UKCA, while Northern Ireland still requires CE. Distribution partners for United Kingdom are being identified ahead of the Q4 2026 launch of the IS-04Z1.

WhereUnited Kingdom
Short answer. United Kingdom has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
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.

More about United Kingdom that matters for portable equipment
United Kingdom: industry on the ground
UK crude oil and condensate production had fallen to about 630,000 barrels a day by 2024, so much of the current work is maintenance, life extension and decommissioning of mature installations.
United Kingdom: industry on the ground
About 98 per cent of UK oil and gas production comes from offshore fields, and the services industry in Aberdeen has been a leader in offshore technology.
United Kingdom: rules and approvals
The Dangerous Substances and Explosive Atmospheres Regulations 2002 require employers to identify and classify areas where explosive atmospheres may occur and to avoid ignition sources from unprotected equipment in them.
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 United Kingdom. A UK marking check reads II 2 G Ex ib IIC T4 and compares it with the zone on the permit. Zone 1 and Zone 2 areas at gas networks, water and waste sites are common inland, and the IS-04Z1 target covers Zone 21 dust as well. The gas group needed depends on the process on site.

Distributing the IS-04Z1 in United Kingdom
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for United Kingdom 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 United Kingdom.
- 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.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · United Kingdom
Frequently asked questions
Can we buy an Ex-proof smartphone in United Kingdom today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an Ex-proof smartphone in United Kingdom 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.
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 sites in United Kingdom does this cover?
The market guide for United Kingdom covers Aberdeen, St Fergus, Sullom Voe, Grangemouth, among others. Site-level pages are linked below.
How do I become a SAMS distributor for United Kingdom?
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 United Kingdom.
What does DSEAR mean for choosing a phone for UK plants?
DSEAR places duties on employers to classify areas where explosive atmospheres may occur and to avoid ignition sources from unprotected equipment. A site will therefore expect devices used in classified areas to be suitable for the zone, gas group and temperature class stated in its area classification records.
Is CE-marked ATEX equipment accepted in Great Britain?
Yes. Since 1 October 2024 CE marking has been recognised in Great Britain without an end date, so an ATEX-certified product can be sold there without UKCA, although a UKCA route with a UK approved body also exists. Northern Ireland still requires CE. Check the current rules before shipping.
How does the IS-04Z1 cope with patchy coverage on a UK platform or rural site?
It combines 4G LTE, Wi-Fi and four-constellation GNSS to hold a position and a connection where one network is not enough. Actual coverage depends on the site, so test the unit on your own route before relying on it.
