The Crosscall STELLAR-M6 is a rugged yet elegant 5G smartphone for mobile professionals who look up and share a lot of information, such as service engineers, retail and logistics staff and customer-facing employees. It is compact enough for one-handed use and does not need an extra case under normal conditions.
The STELLAR-M6 is IP68 dust and waterproof (1.5 metres of salt water, 30 minutes), withstands drops from 1.5 metres onto concrete (24 times, six sides) and meets MIL-STD-810H. The 6.1-inch HD+ display is protected by Corning Gorilla Glass 5 and works with wet fingers and gloves. A top-mounted SOS button and three programmable buttons allow quick operation.
The phone runs on a Qualcomm QCM4490 octa-core processor with 6 GB RAM and 128 GB storage, and supports 5G, Wi-Fi 6/6E with 2x2 MIMO (up to 1.6 Gb/s), VoWi-Fi as a DECT replacement, private networks, dual SIM with eSIM and contactless payment via NFC (EMVCo). An EAL5+ certified Secure Element protects sensitive data.
The 4500 mAh battery delivers up to 35 hours of talk time and up to 400 hours of standby. AI noise reduction of up to -60 dB keeps calls clear. With X-LINK, X-SPACE and X-SCAN, the STELLAR-M6 can also be used as a computer, scanner or PTT device. Crosscall provides a 5-year manufacturer warranty, including the battery.
