An intelligent terminal that allows for replacement of a wireless communication device by a user is disclosed, which comprises an intelligent terminal body and the wireless communication device having a SIM card installed therein. A slot for accommodating the wireless communication device is disposed at a side of the intelligent terminal body, the wireless communication device is detachably inserted in the slot and connected to the intelligent terminal body via an interface, and the outer surface of the wireless communication device matches with the outer surface of the intelligent terminal body. Because the intelligent terminal adopts a wireless communication device whose outer surface matches with the outer surface of the body of the intelligent terminal, the wireless network accessing function of the ultra-thin intelligent terminal (e.g., a tablet computer) is ensured even when no WiFi or 4G network resources are available. Meanwhile, comparing with the external wireless network accessing devices which has protruding part, this intelligent terminal can prevent the wireless network accessing device from being subjected to external impact and the consequent damage on the interface, so the availability and the reliability of the product in use are greatly improved. Moreover, the detachable wireless communication device also makes it convenient for the user to choose different kinds of wireless network accessing devices freely.
