BLU G40 Connectivity and Other Features

Connectivity and Other Features

The BLU G40 offers a decent array of connectivity options. It supports GSM, HSPA, and LTE networks, making it compatible with a variety of service providers. Wi-Fi connectivity includes standards a/b/g/n with options for Wi-Fi Direct, and Bluetooth is available at version 4.2 with A2DP and LE support. The absence of NFC is notable, meaning users seeking mobile payment options may need to look elsewhere. An FM radio is included, providing entertainment without data consumption. The device charges and transfers data via a microUSB 2.0 port, a choice that feels dated but is expected within this price range. Audio needs are met with a loudspeaker and a 3.5mm headphone jack, catering to those who prefer wired audio solutions.
