Networks, connectivity, SAR

Ulefone Armor 21 has a triple-slot tray with two slots for the Nano-SIM cards and a third one for a microSD card. It is positioned on the left frame and can be directly pulled out with a pick or similar tool. Both Nano-SIM cards support 4G connectivity and the following network bands: 2G GSM (2/3/5/8), 3G WCDMA (1/2/4/5/8), 4G FDD-LTE (B1/2/3/4/5/7/8/12/17/19/20/28A/28B/66), and 4G TDD-LTE (34/38/39/40/41). The Armor 21 SAR is as follows: 0.638 W/kg at the head and 0.947 W/kg at the body (EU). The rest of the connectivity options include NFC, Bluetooth 5.2, Wi-Fi 5, Wi-Fi Direct, Wi-Fi Hotspot, and Cast Display. The device also has a built-in antenna that does not require headphones in order to listen to the radio. Furthermore, the Armor 21 has an IR blaster that turns it into a convenient remote control, a USB Type-C 2.0 port, and a headphone jack. The smartphone works with GPS, GLONASS, Galileo, and Beidou. Our review unit managed to detect a huge number of satellites from all positioning systems with excellent accuracy of up to 1 meter. Running on Android 13, the Armor 21 also arrives with Nearby Share and Android Auto on board. Finally, the model features a uSmart connector via which you can plug in an endoscope, magnifier, night vision camera, etc.
