Abstract
A wireless device capable of using multiple SIM cards to simultaneously communicate with multiple cellular networks is presented. The wireless device is a dual-SIM dual-data active device that is capable of receiving and transmitting data packets over multiple cellular networks simultaneously or at substantially the same time. The wireless device may include a second set of antennas and internal hardware, including a second model and processor enabling the wireless device to communicate with at least two cellular networks. The wireless device may select a cellular network to perform a task, such as complete a call or download a video based on a difference in signal strength between the two or more cellular networks supported by the wireless device.
