Celkon A403 Connectivity and Communication

Connectivity and Communication

For connectivity, the Celkon A403 includes Wi-Fi 802.11 b/g/n and Bluetooth 2.0, ensuring basic wireless communication and data transfer. The device supports 3G HSPA network technology, which was standard during its release period, but has become quite slow compared to current expectations of smartphone connectivity capabilities. The absence of NFC is notable, but it includes A-GPS for navigation, which is a useful feature. The inclusion of an FM radio and a 3.5mm headphone jack offers entertainment options listening to music or other broadcasts conveniently.
