Abstract: An electronic device includes a modem supporting a first SIM for using a service of a 5G network of a first telecommunications operator and a second SIM for using a service of a 5G network of a second telecommunications operator, at least one first antenna, and at least one second antenna. The modem may transmit a first signal to a first base station of the first telecommunications operator through the first SIM with a first transmission power by using the at least one first antenna, and while the first signal is transmitted with the first transmission power, transmit a second signal to a second base station of the second telecommunications operator through the second SIM with a second transmission power by using the at least one second antenna, such that a sum of the first and second transmission powers is less than or equal to a predetermined maximum power.
