Gretel GT6000 Review

Networks, calls and connectivity

Gretel GT6000 sports a hybrid, dual-SIM tray. The first slot is for a Nano-SIM or a microSD/TF card, and the second is used for a Nano-SIM card. Both work in a dual standby mode. The first SIM supports 2G GSM (850, 900, 1900, 2100 MHz), 3G WCDMA (900 and 2100 MHz) and 4G FDD-LTE (800, 900, 1800, 2100, 2600 MHz) networks bands. The MT6737 chipset is equipped with an LTE Cat. 4 modem. Our review unit performed perfectly in terms of call quality (especially in 4G) and reception. It did not experience any issues with the wireless connections either. The model supports Wi-Fi 802.11 b/g/n, Wi-Fi Hotspot, Wi-Fi Direct, Cast display, Bluetooth 4.0, and HotKnot. The micro-USB 2.0 port supports OTG and there's a 3.5 mm jack as well. As long as it concerns satellite positioning, the model works with GPS/A-GPS only. Our review unit has managed to detect a good amount of satellites with an excellent accuracy of up to 1 meter.
