Rugged phones are built for trades, logistics, construction and other site work, where a standard handset can have a short life. But rugged spec sheets are full of ratings that are easy to misread, and some tough-looking phones stop getting security updates long before they wear out. This roundup compares the rugged models a UK business can buy in October 2026, explains how to read their ratings, and treats the security support end date as the deciding factor it should be.
Prices are Samsung's launch RRPs or Crosscall's UK store prices on 27 October 2026, and are indicative only.

Do you need a rugged phone at all?
Not always. Most mainstream phones in our best business mobile phones 2026 guide are rated IP68, and in a protective case a standard phone is enough for many field roles. A rugged phone earns its place when phones are often dropped onto hard ground, used in rain and dust all day, washed down, or need a swappable battery. Our guide to business mobile devices for field staff covers the operational side, such as data and rural coverage.
How to read a rugged spec sheet
Three kinds of claim appear on almost every rugged phone.
IP ratings: IP68 and IP69K
Ingress protection (IP) codes come from IEC 60529, with the extra "K" codes defined in ISO 20653, a road-vehicle standard. The first digit covers dust, where 6 means dust-tight. The second covers water: 7 is temporary immersion, 8 is continuous submersion and 9K is high-pressure, steam-jet cleaning. IP68 sets no fixed depth; the maker states the conditions, such as Samsung's "up to 1.5 meters of freshwater for up to 30 minutes". IP69K is a separate high-pressure, high-temperature wash-down test and does not by itself prove a phone can be submerged, which is why rugged phones quote "IP68/IP69K".
MIL-STD-810H
MIL-STD-810H is a US defence test method standard. In its own words it "does not impose design or test specifications"; instead it tells users to tailor which tests they run and at what levels. So there is no single MIL-STD-810H pass. Ask which test methods were used (drop, vibration, temperature and so on), at what levels, and whether an independent lab did the testing. Watch the wording too: Samsung says "built to MIL-STD-810H standards", while Crosscall describes the CORE-Z5 as "designed according to" it.
Drop claims
Drop figures only compare if the height, surface and number of drops match: drops from 1.5m onto steel are a different test from 40 drops from 2m onto concrete. Treat them as each maker's own claims.
Samsung Galaxy XCover7 Pro
On the published facts, the XCover7 Pro is the safest default for a business fleet. Samsung released it in the UK in April 2025 at £559 (Samsung's launch RRP, indicative).
- Toughness: IP68 and built to MIL-STD-810H, with Samsung citing drops onto steel from 1.5m.
- Battery: 4,350mAh and user-replaceable, rated for a minimum of 2,000 charge cycles, so staff can carry a charged spare.
- Connectivity: 5G, a physical SIM plus an eSIM, and a microSD slot (up to 2TB).
- Hardware: a 6.6-inch LCD at up to 120Hz, Snapdragon 7s Gen 3, 6GB of memory and 128GB of storage.
- Security updates: until 31 May 2032, according to Samsung's UK product page.
Currys Business lists an Enterprise Edition and describes it as Android Enterprise Recommended; we could not confirm that status in Google's own directory.

Samsung Galaxy XCover7
The cheaper XCover7 launched in January 2024 at £349 (Samsung's launch RRP, indicative). It shares the essentials: IP68, MIL-STD-810H, drops onto steel from 1.5m, a user-replaceable 4,050mAh battery, 5G, SIM plus eSIM and a 6.6-inch screen.
The catch is support. Samsung's UK page offers up to four OS upgrades and up to five years of security updates, valid until 28 February 2029. A Samsung Switzerland business document lists a longer period, but the UK page is the one to plan around. That leaves about two years and four months from today (our calculation), so it suits short projects or spares rather than a new three-year fleet. Check it is still available before you budget for it.
Crosscall CORE-M6 and CORE-Z5
Crosscall is a French rugged specialist with a UK online store. Its security update page lists the month after which each model's updates are "not guaranteed".
CORE-M6
Launched in December 2025 and listed at £299.90 on Crosscall's UK store on 27 October 2026 (store price, indicative), the CORE-M6 has the lowest price in our comparison table and one of the latest support dates.
- Crosscall quotes 40 drops from 2m onto concrete (plus 300 from 1.2m) and MIL-STD 810H. Its marketing says IP68/IP69K, but its own specification table lists IP68 only.
- A 5.99-inch screen, 6GB of memory, 128GB of storage and a 4,950mAh battery, plus a battery-free mode that runs the phone from a USB-C cable.
- 5G, two nano-SIM slots (one can take a microSD card instead) and an eSIM.
- Android 15 at launch, with Android 16, 17, 18 and 20 planned, subject to Crosscall's compatibility checks.
- A five-year manufacturer's warranty, battery included.
- Security updates until December 2033 on the security page, although the December 2025 launch release said December 2032. The earlier date is the safer one to plan around.
CORE-Z5
The older CORE-Z5 costs more, at £564.90 on Crosscall's UK store (store price, indicative), but its support ends sooner, in December 2032. Crosscall quotes 2m drops onto concrete on all six faces, IP68 and a design "according to" MIL-STD-810H. It has a 6.08-inch screen, 128GB of storage plus microSD, a 4,950mAh battery and two nano-SIM slots, but no eSIM is listed. The page gives 6GB of memory in its table and 4GB in its marketing text, so confirm which version you are quoted. It launched on Android 12, now runs Android 14 and has one more upgrade, to Android 16, planned.
Crosscall STELLAR-X5s and STELLAR-M6
The STELLAR-X5s has a 6.497-inch screen, 8GB of memory, 256GB of storage and a 4,500mAh battery. It is IP68 and MIL-STD 810H, survives 40 drops from 1.5m onto concrete on all six sides by Crosscall's account, and has 5G with nano-SIM and eSIM. It was listed at £629.90 on Crosscall's UK store on 27 October 2026 (store price, indicative).
Its support date is the most confusing in this roundup. The product page says updates are guaranteed until December 2031, with three Android upgrades to Android 18, while Crosscall's security page says December 2033. Until Crosscall clarifies, plan on December 2031.
The cheaper STELLAR-M6, at £359.90 (Crosscall UK store price, indicative), has the latest date in Crosscall's table, December 2034. It has a 6.1-inch screen, a 4,500mAh battery rated for a minimum of 1,000 cycles, eSIM, IP68 and 24 drops from 1.5m onto concrete.

HMD XR21
The HMD XR21 began life as the Nokia XR21 in May 2023 and was relaunched under the HMD name in May 2024. It is tough on paper: HMD lists IP68/IP69K and MIL-STD-810H, and the original Nokia datasheet states MIL-STD-810H certified drop protection up to 1.5m. It has a 6.49-inch screen, 5G, 128GB of storage, a non-removable 4,800mAh battery, an eSIM plus two nano-SIM slots and a warranty of up to three years.
The problem is age. It launched on Android 13 with two years of OS upgrades, and HMD's own pages put the end of updates at July 2027, August 2027 or "summer 2027". Whichever is right, that is less than a year away, so we would not choose it for a new deployment. We could not confirm its current UK price.
Budget import brands and Cat phones
Online marketplaces sell cheaper rugged phones from brands such as Doogee, Blackview and Ulefone, often with very large batteries and IP68/IP69K claims. For a business, the issue is support:
- We found no published security update period for Doogee, Blackview or Ulefone phones. Ulefone commits only to "at least two Android OS updates" for eligible new models.
- Spec pages can contradict themselves: Doogee's S200 page says IP68 in one place and IP68/IP69K in another.
- Some are 4G only: the Blackview FORT 5 has no 5G.
- We could not confirm UK availability through official channels for these brands.
Cat phones are a different story. Bullitt Group, which made Cat-branded phones, went into administration on 28 February 2024. The Cat brand has since been licensed to Orbic, which showed new Cat models only as mock-ups at MWC 2025, and we found no evidence of Orbic-built Cat phones on sale in the UK, so check the age and update status of any Cat phone you are offered. Sonim's XP Pro, sold in the US, publishes a May 2030 security end date, but we could not confirm UK availability.
Rugged phones side by side
| Phone | Price (indicative) | Rugged claims, as stated | Security updates, as stated |
|---|---|---|---|
| Galaxy XCover7 Pro | £559 launch RRP | IP68, MIL-STD-810H, 1.5m onto steel | Until 31 May 2032 |
| Galaxy XCover7 | £349 launch RRP | IP68, MIL-STD-810H, 1.5m onto steel | Until 28 Feb 2029 |
| Crosscall CORE-M6 | £299.90 store price | IP68 (IP69K in marketing), MIL-STD 810H, 2m onto concrete | Dec 2033 (launch release: Dec 2032) |
| Crosscall CORE-Z5 | £564.90 store price | IP68, designed to MIL-STD-810H, 2m onto concrete | Dec 2032 |
| Crosscall STELLAR-X5s | £629.90 store price | IP68, MIL-STD 810H, 1.5m onto concrete | Dec 2031 or Dec 2033 (Crosscall pages differ) |
| Crosscall STELLAR-M6 | £359.90 store price | IP68, MIL-STD 810H, 1.5m onto concrete | Dec 2034 |
| HMD XR21 | Not confirmed | IP68/IP69K, MIL-STD-810H, 1.5m | Mid-2027 |
On these figures, the XCover7 Pro and CORE-M6 stand out: both combine strong drop claims, eSIM and support well into the 2030s, at very different prices. The XCover7 Pro adds a user-replaceable battery; the CORE-M6 adds a longer warranty.
Buying and managing rugged phones
- Batteries. Samsung's two XCover models are the only phones here whose maker lists a user-replaceable battery. HMD says the XR21's is non-removable, and Crosscall's pages do not say either way, so ask before you assume.
- Warranty and replacement. Crosscall gives the CORE-M6 a five-year warranty including the battery, and HMD offers up to three years on the XR21. Samsung's Enterprise Edition terms include a three-year warranty and a next-business-day replacement service.
- Device management. Samsung's Knox Suite Base Plan, including Knox Mobile Enrolment, comes with Galaxy purchases at no extra cost, and Crosscall lists zero-touch enrolment support on its models. Enrol every phone in mobile device management (see our Intune guide) so a lost handset can be locked or wiped; our guide to a lost or stolen business mobile covers the rest.
- eSIM. Every phone in the table except the CORE-Z5 lists eSIM, which lets you activate a line remotely for staff who rarely visit the office. Our eSIM for business guide explains how.
- Support dates. Record each phone's end date and plan its replacement before then. Google's Android Enterprise Recommended requirements for rugged devices ask makers to publish a security support end date, a sensible bar for any supplier. Our guide to business phone security update periods explains why the date matters for Cyber Essentials.
- Coverage. Check coverage where your teams work with our business network comparison.
