The Sonim Xp3 and Xp3Plus are small compact modern day flip phones that do what they are designed to do well, call and be used for PTT apps.
Whether it's on a job site or in a city work truck, you may be surprised at what a big difference such a small device can make for your fleet.
The Sonim XP3: Rugged, Compact, and Work-Ready
The Sonim XP3 is a purpose-built tool for the modern jobsite, backed by US-based customer service and an industry-leading 3-year warranty. It offers a no-nonsense approach to connectivity for those who need a device that won't shatter on concrete.
Design and Durability
Built like a tank, the XP3 features a tactile grip and a compact form factor engineered to withstand drops, dust, and water.
• The Build: A large flat-head screw secures the battery door for a water-tight seal, while rear contact pins support professional chargers and vehicle mounts.
• Interface: It includes a clear display and a full numerical keypad for functional, tactile dialing.
• Controls: A dedicated Push-to-Talk (PTT) button and volume rockers are on the left. These may be difficult to manipulate by feel alone when wearing heavy work gloves.
Streamlined Communication
The XP3 runs a specialized, locked-down version of Android to ensure stable mission-critical communication.
• Optimized Apps: It is limited to specific tools like Zello and Zello Work, which are tuned for Sonim hardware.
• Zello Integration: Because there is no Google Play Store, the specific APK must be sideloaded. Once configured, it functions like a traditional radio even when the flip is closed.
Performance and Battery Life
The XP3 consistently delivers 2+ days of battery life with light Zello activity and standard calling, easily lasting through a hard day's work.
Accessories: The Speaker Mic Experience
Wired speaker mics used via the 3.5 mm jack can be inconsistent. In several tests, the mic remained "hot" after the button was released. A Bluetooth PTT accessory is recommended for a reliable hands-free experience.
Final Thoughts
The Sonim XP3 is an excellent fleet device where durability and domestic support are non-negotiable.
Pros:
• US-based customer service and 3-year warranty.
• Compact, highly durable form factor.
• Exceptional battery life.
Cons:
• Side buttons can be tricky with heavy gloves.
• Wired speaker mic integration is inconsistent.
