Connectivity
Network technologies supported by the Cubot J20 include GSM, HSPA, and LTE, with a range of frequency bands ensuring decent coverage and connectivity. For local wireless connections, it employs Wi-Fi 802.11 b/g/n, Bluetooth 4.2 with A2DP, and offers GPS, GLONASS, and GALILEO for positioning services. The lack of NFC might be a drawback for those who use contactless payment systems. Moreover, while a 3.5mm audio jack is present for traditional audio connections, details about FM radio capability are unspecified.
