Networks, connectivity

The 8849 Tank 3 Pro by Unihertz has a triple-slot tray for two Nano-SIM cards and a microSD card. Both SIM cards support 5G connectivity simultaneously. The network bands supported by both cards are as follows: 2G GSM (B2/3/5/8), 2.5G (BC0/BC1), 3G WCDMA (B1/2/4/5/6/8/19), 4G TDD-LTE (B34/38/39/40/41), 4G FDD-LTE (B1/2/3/4/5/7/8/12/13/17/18/19/20/25/26/28A/28B/66), and 5G (N1/2/3/5/7/8/12/20/25/28/38/40/41/66/77/78). The wireless connectivity options of the model include Bluetooth 5.3, Wi-Fi 6E (802.11ax), Wi-Fi Direct, Wi-Fi Hotspot, and Cast Display. The smartphone also supports NFC and has an IR blaster. The latter allows you to use the device as a remote controller of household appliances and electronics. The model also works with GPS, GLONASS, Galileo, and Beidou. Our review unit managed to detect an impressive number of satellites with an excellent accuracy of up to 1 m. It is also fitted with a USB Type-C 2.0 port with OTG (10W reverse charging is supported) and a 3.5 mm jack.
