Cubot King Kong 3 Review

Networks, calls and connectivity

Cubot King Kong 3 has a hybrid, dual-SIM tray placed on the left frame. With it, you can use either two Nano-SIM cards or a Nano-SIM and a microSD card with up to 128GB capacity. The two SIM cards work in a dual-standby mode and should both support simultaneous 4G connections. However, our review unit shows that it offers 2G, 3G and 4G support for the first card and only 2G bands for the second card. We have Cubot's confirmation that the final version of the software will make sure that the handset will indeed support dual 4G. The supported network bands include 2G GSM (850, 900, 1800, 1900 MHz), 3G W-CDMA (900 MHz, 2100 MHz), and 4G FDD-LTE (700 MHz Class 17, 800, 850, 900, 1700/2100, 1800, 1900, 2100, 2600, 700 MHz (B12)). LTE speeds are Cat. 6 ones. The smartphone works with GPS and GLONASS. Our review unit was very quick in finding a good number of satellites from both with an excellent accuracy of up to 2 meters. The wireless connectivity options of the model include Bluetooth 4.2, dual-band Wi-Fi 802.11 a/b/g/n, Wi-Fi Direct, Wi-Fi Hotspot. The handset is equipped with a USB Type-C 2.0 port and does not have a 3.5 mm jack. However, the model supports NFC with a full set of options, including P2P mode for sending and receiving Android content, Android Beam, tag reading and writing, card emulation, Tap & pay.
