Sonim XP3plus 4G Rugged Flip Phone
The Sonim XP3plus is a rugged clamshell phone designed for clear, crisp communication and built-for-work features, without the cost or distraction of a smartphone. Its simple, reliable design ensures the job gets done right, backed by an industry-leading three-year comprehensive warranty.
Rugged credentials. Sealed to IP68 and tested to MIL-STD-810H, the XP3plus resists water, dust and drops and runs reliably from -20C to +55C. The flip design protects the keypad and main display, while a secondary external display shows calls and notifications at a glance.
Tailored to how you work. A larger dynamic internal screen with programmable buttons lets you adapt the device to your workflow, and a front-facing 100dB+ speaker with noise cancellation stays loud and clear in the noisiest environments.
Practical and dependable. A removable 2300mAh battery, dual-SIM support, expandable storage up to 256GB, an 8MP camera, FM radio and dedicated Push-to-Talk and emergency keys make the XP3plus ideal for construction, utilities, logistics, agriculture and field service. A non-camera variant is available for secure environments.

Yes. Sonim’s current range includes ultra rugged 5G smartphones and a 5G mobile rugged hotspot, bringing modern high speed connectivity to hardened field devices. This means teams in industrial and public safety roles can benefit from 5G performance without sacrificing the durability their environment demands. The 5G hotspot extends resilient connectivity to other devices in the field, useful where reliable network access is critical and conditions are tough. Exact network bands, carrier support and configuration vary by model and region, so buyers should confirm the specific connectivity details on the individual product page to ensure the device matches their network and operational requirements.
Yes. Alongside its ultra rugged smartphones, Sonim offers a rugged 5G mobile hotspot for resilient field connectivity and a thermal imaging rugged handset for specialised applications. The hotspot provides durable, portable network access where reliable connectivity is needed in tough conditions, while the thermal imaging device adds capability for inspection, safety and field tasks that benefit from heat detection. These products complement Sonim’s core handset range, allowing teams to source rugged communications and connectivity hardware from a single specialist. Exact specifications, network support and features vary by model, so confirm the full details on each individual product page when matching a device to your application.
A rugged case adds limited protection to a phone that was never engineered for harsh use, whereas a Sonim handset is built ultra rugged from the inside out, with a sealed and reinforced design engineered to ingress protection and durability standards across the device, not just the casing. That means resistance to drops, dust and water is part of the hardware rather than an accessory bolted on afterwards. For workers who depend on their phone as critical field equipment, this matters, because the weak points of a cased consumer phone, such as ports, screen and seals, remain vulnerable. Sonim’s purpose built approach delivers reliability that a case cannot match.
Sonim is a United States manufacturer known for ultra rugged smartphones built for industrial and public safety users. Where most phones are designed for everyday consumer use, Sonim handsets are engineered to survive drops, dust, water and harsh handling on the front line and in the field. The range includes ultra rugged 5G smartphones, an ATEX certified model for hazardous areas, a thermal imaging handset and a rugged mobile hotspot. Sonim is a recognised choice for utilities, construction, manufacturing, logistics and emergency services teams who need a phone that keeps working in conditions that would quickly destroy a standard consumer device.
Sonim specialises in ultra rugged smartphones and connectivity devices for demanding industrial and public safety environments. Its catalogue centres on ultra rugged 5G handsets engineered to withstand drops, ingress, dust and rough handling, and extends to an ATEX certified smartphone for hazardous areas, a thermal imaging handset, and a rugged 5G mobile hotspot for resilient field connectivity. This focus on hardened handheld communications sets Sonim apart from consumer phone makers. The devices are built for workers who rely on their phone as critical field equipment, where a cracked screen or water damaged handset is not a minor inconvenience but a genuine operational and safety risk.
Yes. Sonim’s range includes an ATEX certified 5G ultra rugged smartphone designed for use in potentially explosive atmospheres, such as those found in oil and gas, chemical processing and other hazardous area operations. ATEX certified handsets are engineered and certified to operate safely in classified zones where standard phones are not permitted. Because zone suitability and certification details differ by model, buyers should confirm the specific ATEX rating, approved zones and configuration on the individual product page before purchase. For teams working in hazardous environments, a correctly certified Sonim handset provides rugged communications without compromising on the safety compliance those areas demand.
Sonim phones are engineered as ultra rugged devices, a different class to a consumer smartphone. Where an ordinary handset is built for careful everyday use, Sonim handsets are designed to survive repeated drops, dust, water exposure and rough handling in the field, commonly engineered to recognised ingress protection and MIL-STD-810 style durability testing. Exact ratings vary by model and should be confirmed on each product page. The practical difference is dramatic in harsh settings, where a consumer phone may crack, fail or suffer water damage quickly, while a Sonim device is built to keep working. That resilience is why frontline and field teams choose Sonim.
Sonim ultra rugged smartphones are used across utilities, energy, construction, manufacturing, logistics, transport and public safety, including emergency services. These are environments where workers handle their phone in dusty, wet, cold or high impact conditions, and where a failed device disrupts communication and safety. Sonim’s ATEX certified handset extends suitability into hazardous areas such as oil and gas and chemical processing, while its thermal imaging model and rugged hotspot serve more specialised field needs. Across all of these sectors, organisations choose Sonim because its handsets are engineered as durable field tools rather than consumer phones, keeping critical communications running in demanding daily use.
