Both cards support 4G connectivity simultaneously as well as the following network bands: 2G GSM (2/3/5/8), 2.5G (BC0/BC1), 3G WCDMA (1/2/4/5/8), 4G TDD-LTE (34/38/39/40/41), and 4G FDD-LTE (1/2/3/4/5/7/8/12/13/17/18/19/20/25/26/28A/28B/66). The EU SAR is 0.155 W/kg at the head and 0.683 W/kg at the body. The USA SAR is 0.227 W/kg at the head and 0.793 W/kg at the body. The wireless connectivity options of the model include Bluetooth 5.3, dual-band Wi-Fi 802.11ac, Wi-Fi Direct, Wi-Fi Hotspot, and Wi-Fi Display. The smartphone also supports NFC and has an IR blaster that turns the device into a TV remote controller. The handset works with GPS, GLONASS, Galileo, and Beidou. Our review unit has detected plenty of satellites with excellent accuracy of up to 1 meter. The smartphone is fitted with a USB Type-C 2.0 port with OTG that allows it to serve as a power bank and a 3.5 mm jack. Running on Android 12, the Tank also arrives with Nearby Share and Android Auto on board.
