Need a duty belt holster for the new Crosscall Core-P6? Turtleback makes one, custom-molded around the Core-P6's exact dimensions so it stays secure on a 2.25 inch duty belt.

AT&T launched the Core-P6 in June 2026 as a new FirstNet-approved push-to-talk device for fire, police, EMS, and enterprise customers. It's Crosscall's first device built specifically for the US and Canada market, after years as an established radio brand in Europe, particularly France.

If your department is issuing these or you're picking one up for field work, we’ll go over what the device actually offers, and how to carry it on duty.

What Is the Crosscall Core-P6?

The Core-P6 is a rugged push-to-talk radio that combines classic radio ergonomics with Android-powered broadband features. It's built around a T-shaped body with a large, glove-friendly PTT button and a top-mounted rotary channel selector, so it handles like a radio even though it runs on Android underneath.

Is It FirstNet Approved?

Yes. The Core-P6 is FirstNet approved through AT&T, and it's compatible with FirstNet Fusion, AT&T Enhanced Push-To-Talk, and FirstNet Rapid Response. That makes it a direct option for fire, police, EMS, and enterprise customers already operating on AT&T's public safety network.

What Communication Features Does the Core-P6 Have?

The Core-P6 pairs a large glove-friendly PTT button with a 16-position rotary channel selector, a dedicated SOS button, and three-microphone audio pickup with AI noise reduction.

• Large-format PTT button (29.6 x 10.2mm), calibrated for reliable activation even with thick gloves
• 16-position rotary channel selector, top-mounted for quick access without looking down
• SOS button, positioned on the upper part of the device
• 360° audio capture via three internal digital microphones protected by a GORE membrane
• AI noise reduction up to -60dB, plus anti-feedback, echo cancellation, and wind noise suppression
• Speaker output up to 105dB, front-facing for clear communication in loud environments

How Rugged Is the Crosscall Core-P6?

The Core-P6 is rated IP68 and IP69K, meets MIL-STD-810H military durability standards, and is built to survive drops of up to 6.6 feet onto concrete. It also carries an IPX8 saltwater rating for 2 meters of exposure over 30 minutes.

• IP68 and IP69K rated for dust and water resistance
• MIL-STD-810H military durability standard
• Drop-tested to 6.6 feet (2 meters) onto concrete
• IPX8 saltwater resistance, 2 meters for 30 minutes
• Operating range of -4°F to 140°F (-20°C to 60°C), extending to -22°F to 158°F (-30°C to 70°C) when powered externally via USB-C or X-LINK

The 2-inch non-touch LCD is protected by reinforced Corning Gorilla Glass. The removable, IP68-rated battery uses a mechanical locking system so it stays in place in the field.

Battery, Connectivity & Extras

The Core-P6 runs on a 4,000 mAh removable battery, rated for up to 58 hours 32 minutes of PTT use, up to 21 hours 36 minutes of continuous talk time on 4G/5G, and up to 15 days 8 hours on standby. Apple-style fast charging isn't the focus here, but it does reach 80% in about an hour.

Beyond voice, the device includes front and rear 8MP cameras for evidence collection and video calls, an instant Wi-Fi hotspot for sharing data with up to 10 connected devices, 5G connectivity, dual-SIM support, and a lockable USB-C port for secure accessory connections. It's also built around the X-LINK and Klick Fast accessory ecosystems, giving departments options for mounting, charging, and carrying beyond a standard belt holster.

Crosscall backs the Core-P6 with a 3-year warranty that includes the battery — notable for a device this rugged, where battery wear is often the first real point of failure.
