FIELD: wireless communication.
SUBSTANCE: invention relates to wireless communications. A wireless device capable of using multiple SIM cards for simultaneous communication over multiple cellular networks is proposed. A wireless device is a device with two active dual-mode SIM modules that is capable of receiving and transmitting data packets over multiple cellular networks simultaneously or almost simultaneously. The wireless device may include a second set of antennas and internal equipment, including a second modem and a processor, allowing the wireless device to communicate with at least two cellular networks. The wireless device can select a cellular network to perform a task, for example, making a voice call or downloading a video based on the difference in signal strength values between two or more cellular networks supported by the wireless device.
EFFECT: ensuring the maintenance of communication channels over a variety of data transmission networks.
