Connectivity
In terms of connectivity, the Celkon A407 supports dual-SIM functionality, which is useful for users managing multiple numbers. It operates on GSM and HSPA network technologies, limiting its use to 3G speeds, which can be restrictive in areas where faster networks are the norm. It includes Wi-Fi 802.11 b/g/n, Bluetooth 2.0, GPS for basic location services, and FM radio, covering essential communication and entertainment needs. Lack of NFC and limited Bluetooth capabilities restrict its functionality compared to newer models.
